BSP Female 60 Degree Cone Fittings (22611 Series): ISO 12151-6 Crimp Hose Fittings

Quick answer: A BSP female 60 degree cone fitting is a crimp-on hydraulic hose fitting with a female parallel G thread and a machined 60 degree internal cone seat. It seals metal-to-metal against a male 60 degree cone stud, which makes it the standard BSP connection for hydraulic hose in Europe, Asia and most export machinery markets.

BSP female 60 degree cone fittings connect hydraulic hose to machine ports, valves and adapters that terminate in a male 60 degree cone. Our 22611 series covers this connection as a complete, crimp-ready line: 26 part numbers from G1/8″ to G2″, hose bores DN 5 to DN 50 (dash -03 to -32). Every fitting is engineered to ISO 12151-6 for hose fittings with ISO 8434-6 60 degree cone ends, and the parallel G threads follow ISO 228-1.

Because the seal is a machined metal-to-metal 60 degree cone contact, the fitting does not depend on thread tape, sealant or O-rings at the cone. That means a repeatable, leak-free BSP joint every time you torque the nut onto a clean male cone. Zinc-plated carbon steel is the standard finish; 304 and 316L stainless steel versions serve marine and washdown environments.

Core Selling Points

These 60 degree cone hydraulic fittings are built for daily service in crimped hose assemblies, and every detail below is checked before packing.

• ISO 12151-6 compliant geometry. 60 degree cone seat matches ISO 8434-6 male cone studs, with parallel BSPP G threads per ISO 228-1. The 60 degree cone seal needs no O-ring at the joint, which removes a common leak point. This is the compliance gate for OEM buyers and a quality mark for the aftermarket.
• One series, 26 part numbers. Threads G1/8″ to G2″ and hose bores DN 5 to DN 50 mean this BSP female swivel range covers most BSP hydraulic circuits, from instrumentation lines to main return lines.
• Corrosion protection that lasts. Trivalent (Cr6-free) zinc plating passes 144 hours of neutral salt spray without red rust. Stainless steel 304/316L is available for saltwater and chemical washdown duty.
• Crimp-ready precision. Insert profiles are machined for 1SN and 2SN hose classes, and every fitting is gauge-checked before packing. Fittings are tested to ISO 19879; complete hose assemblies are impulse-tested to ISO 6605.

What Are BSP Female 60 Degree Cone Fittings?

The 60 degree cone system is one of the oldest and most widespread BSP sealing methods in hydraulics. The female half of the joint carries a parallel G thread (BSPP) plus an internal 60 degree cone seat. The male half carries a matching external 60 degree cone. When the nut is tightened, the two cones wedge together and form a metal-to-metal seal. The 60 degree cone metal-to-metal seal removes the soft element that fails first on flat-seat joints. No elastic seal element sits in the pressure path, so the joint resists high pressure, temperature swing and aging far better than thread-sealed connections. This is why 60 degree cone hydraulic fittings remain the default BSP choice for European and Asian machine builders: simple geometry, no soft seal to age, and easy hose-end orientation before tightening.

In a hose assembly, the female 60 degree cone end is combined with a barbed tail that is crimped onto the hose with a steel ferrule. The result is a factory-grade, permanent hose end. Because the nut is a BSP female swivel, you can orient the hose freely and tighten it without twisting the hose. This design is defined internationally:

• ISO 12151-6:2009 – Hose fittings with ISO 8434-6 60 degree cone ends (hose bores DN 5 to DN 51 per ISO 4397).
• ISO 8434-6:2009 – 60 degree cone connectors with or without O-ring for metallic tubes and ports.
• ISO 228-1 – Parallel G (BSPP) thread form and tolerances.

Note for spec writers: this 60 degree cone BSP system is not defined in SAE J516. If your project specification cites SAE J516 only, confirm with your engineer whether BSP 60 degree cone ends are accepted; if your machine base is European or Asian export equipment, ISO 12151-6 is the governing hose fitting standard.

BSP Female 60 Degree Cone Fitting Specifications

Material and Surface Finish

Material and finish values above are typical executions for this series. Confirm the exact grade, plating thickness and hardness target with our engineers when you place the order, and request the batch MTR with your shipment.

22611 Series Dimension Table (MPN Matrix)

Dimensions in mm, per the factory specification sheet. Part numbers use the pattern 22611 – [thread code] – [hose dash]. Rows marked T or W carry tail-profile variants for different hose constructions; select the stem profile together with your hose series.

A and C are the mounting dimensions shown on the sub-drawings for the 22611, 22611-T and 22611-W profiles. Request the certified dimensional drawing (DXF or PDF) for your exact part number before tooling up.

Crimp Parameters: Insert Depth and Crimp O.D.

Insert depth and crimped outside diameter are hose-series-specific, not fixed fitting constants. The correct values depend on the hose construction (for example EN 853 1SN or 2SN, SAE 100R1AT or R2AT) and the ferrule family.

Send us your hose brand and series, or the hose data sheet, and our engineers will return the matching crimp specification within 24 hours: insert depth, ferrule part number, crimp die number and target crimp O.D. with tolerance. For quality control in your workshop, always measure the crimp O.D. with a caliper after every crimp and record it against the target value.

Pressure and Temperature

A crimped hose end is only as strong as the weakest element. The working pressure of the complete assembly is governed by the hose and the ferrule, so the fitting is qualified for the full rated pressure of the matched hose series. Indicative maxima for common classes are shown below; confirm against the hose data sheet before design release.

Temperature range for the assembled connection is typically -40 C to +120 C, limited by the hose cover and inner tube material. The metal cone seal itself does not degrade with temperature within this band. Request our pressure-temperature derating chart for your exact hose selection.

Selecting the Right BSP Female 60 Degree Cone Fitting

Three Questions, One Part Number

1. Read the nut thread. The nut is marked or measured as G1/8″, G1/4″, G3/8″, G1/2″, G5/8″, G3/4″, G1″, G1-1/4″, G1-1/2″ or G2″. This is the thread code in the part number (02, 04, 06, 08, 10, 12, 16, 20, 24 or 32).
2. Read the hose bore. Match the hose inner diameter in mm (DN 5 to DN 50) to the dash column (-03 to -32).
3. Read the part number. The intersection of thread code and dash is your ordering code, for example 22611-08-08 = G1/2″ x DN 12. For T and W rows, confirm the tail profile against your hose series with our engineers.

Select by Thread Size

Every size in this matrix is supplied as a BSP female swivel nut over a fixed tail, so the fitting self-aligns during assembly and needs no thread sealant at the cone.

Identify a Replacement Fitting

If you are replacing an existing female BSP hose end, you do not need its old brand name. Measure three things and the part number falls out of the table:

• Hex across flats (S2) with a caliper: 14, 19, 22, 27, 30, 32, 41, 50, 55 or 70 mm.
• Thread size and pitch with a thread pitch gauge: G threads are parallel; pitch is 28, 19, 14 or 11 TPI depending on size.
• Cone seat angle: our seat is a true 60 degree cone. Never match it to a 30 degree JIS cone or a 24 degree DIN cone seat, and never pair it with a tapered BSPT male thread.

This series is the dimensional equivalent of the standard European BSP female 60 degree cone swivel hose fitting family (ISO 12151-6 design type SWSB). If the original fitting’s hex, thread and hose bore match the table above, our 22611 series is a drop-in replacement for the hose assembly.

Packaging and Logistics

Standard packaging is 10 pieces per poly bag with a label showing part number, batch and quantity, then export cartons with inner protection. Gross weight per carton and country of origin are stated on the commercial documents and can be provided in advance for your freight calculation. Mixed-size and mixed-thread kits are available for distributors.

How to Crimp BSP Female 60 Degree Cone Fittings

Assembly Guide (Four Steps)

1. Cut the hose square. Use a sharp hose cutter or a cutoff wheel. A square, burr-free cut is the difference between a seal that lasts and a weep that does not. Compare the cut face against a square reference before you continue.
2. Mark the insert depth. Push the ferrule onto the hose first, then mark the insert depth line on the hose cover with a pen. The depth value comes from the crimp specification for your hose series. Do not guess it.
3. Insert and push home. Lubricate the hose bore and the stem with a light assembly lubricant, then push the stem into the hose with a twisting motion until the hose cover reaches the depth mark. A rotary or bench press makes this step consistent.
4. Crimp and verify. Crimp with the matched die set, then verify with a caliper: measure the crimped O.D. at two points and compare both readings with the target value and tolerance from the crimp chart. Record the readings on the assembly sheet. A crimp outside tolerance must be cut off and re-made, never shipped.

Warnings (Read Before Crimping)

• Never mix hoses and fittings from different suppliers on one assembly, even when the dash size matches. Insert depth, stem profile and crimp O.D. are matched as a system; mixing them is the most common cause of hose pull-out and burst at the fitting.
• The 60 degree cone seal needs a clean, undamaged cone on the male side. A scratched or pitted cone will leak regardless of torque. Replace the male part if the cone is damaged.
• Do not use thread sealant tape on the cone itself. The G thread is a parallel fastening thread; sealing happens at the cone. Tape on the cone face prevents metal-to-metal contact and causes leaks.
• Parallel G (BSPP) threads seal by cone contact or by washer/O-ring where designed. Tapered BSPT threads seal by thread interference and need sealant. These two systems are not interchangeable. Confirm which one your port uses before ordering.
• Tighten the nut with the correct wrench size (S2) and moderate torque. The seal forms when the cones touch; excessive torque can distort the seat.

OEM Customization and Quality Traceability

Customization Services

• Tail profile customization. Non-standard stem profiles matched to your proprietary hose construction, including special insert depths for spiral hose.
• Surface treatment customization. Zinc-nickel or Dacromet coatings with defined salt spray grades for coastal and mining duty.
• Laser marking. Your logo, part number and batch code marked on the hex, giving you full field traceability and brand presence on every assembly.
• Packaging and kitting. Private-label packaging, set kits per machine model, and barcode labels for your warehouse system.

Quality Traceability

Every batch follows the same chain: incoming steel certificates are checked at the gate, forging and machining parameters are recorded, plating thickness is sampled per batch, and 100% of fittings are gauge-checked for thread and cone geometry before packing. Each carton carries a batch heat number, so we can pull the MTR and process records for any shipment within one working day. Third-party inspection reports from BV or SGS can be arranged before dispatch, and sample reports are available on request.

BSP Female 60 Degree Cone Fittings FAQ

Q1: What is a BSP female 60 degree cone fitting? A female hose fitting with a parallel G thread nut and an internal 60 degree cone seat. It crimps onto the hose and seals metal-to-metal against a male 60 degree cone stud, per ISO 12151-6 and ISO 8434-6. It is one of the most widely stocked 60 degree cone hydraulic fittings in BSP systems.

Q2: What is the difference between BSP female 60 degree cone and a flat-seat BSPP fitting? A flat-seat BSPP female needs a bonded washer or O-ring to seal. The 60 degree cone version seals by cone-to-cone metal contact, which handles higher pressure and repeated temperature cycles without a soft element to replace.

Q3: Can I use this fitting with BSPT (tapered) male threads? No. G threads here are parallel (BSPP). BSPT is a tapered thread with a different sealing concept and will not form the correct 60 degree cone joint.

Q4: Which hoses work with the 22611 series? The series covers hose bores DN 5 to DN 50. Standard stem profiles suit EN 853 1SN and 2SN classes; T and W variants extend coverage across heavier constructions. As with all hydraulic hose crimp fittings, the stem profile must match the hose series, so send your hose data sheet and we will confirm the match before you order.

Q5: What is the maximum working pressure? The fitting is qualified for the full rated pressure of the matched hose assembly, tested to ISO 19879 and ISO 6605. Typical 2SN assemblies range up to about 400 bar at -04 size and derate by size; see the indicative table above.

Q6: Do I need thread sealant or PTFE tape? No. The metal-to-metal seal is formed by the cone contact itself, so keep the cone clean and torque the nut correctly. Thread sealant is only relevant if the male end is tapered BSPT, which is a different system.

Q7: Is stainless steel available? Yes, 304 and 316L executions are produced on request for marine, food and washdown applications. Salt spray performance and MTR certificates are provided with each stainless batch.

Q8: What is the minimum order quantity and lead time? Standard sizes from stock or short production runs carry a low MOQ. OEM programs with custom marking and packaging are quoted with a schedule at inquiry. Email us your part number list for a same-day stock check.
