BSP Female 60° Cone O-Ring Fitting: 22613-ORW Series

Why This BSP Female 60° Cone O-Ring Fitting Passes the Compliance Gate

A BSP female 60° cone O-ring fitting joins a braided hydraulic hose to a BSPP 60° cone connection with an elastomer seal: a swivel nut with an internal parallel G thread pulls the fitting’s 60° cone face into the mating seat, and an O-ring seated on the cone does the sealing. The 22613-ORW series from HENGHUA is the large-size O-ring execution of the BSP 60° cone family, referenced to BS 5200 on the factory drawing and built to the ISO 12151-6 hose fitting geometry with ISO 8434-6 60° cone ends. It covers four part numbers from -12 to -24 with G-series parallel threads from G3/4″ to G1.1/2″. Every unit is cold-forged from carbon steel, heat-treated, plated, and 100% pressure tested before shipment. For OEM buyers this fitting is a compliance gate; for maintenance teams it is the O-ring cone termination that seals positively even when the mating seat shows service wear.

• O-ring cone sealing: an O-ring is seated on the 60° cone face of the fitting body; when the nut is tightened, the cone centres the joint and the O-ring compresses against the mating seat. The seal is elastomer, not metal-to-metal, so it tolerates minor seat surface marks better than a plain cone joint.
• ISO 12151-6 / ISO 8434-6 geometry: the 60° cone end and G thread follow the ISO 8434-6 cone system with the O-ring variant, and the hose fitting end is built per ISO 12151-6. The G thread is parallel (ISO 228-1) and only holds the connection.
• Swivel nut design: the drawing shows a single hexagon, S2, on the swivel nut; the nut is captive on the body and rotates freely, so the hose can be oriented before final torque and is never twisted by the connection.
• Four large-bore sizes: -12 to -24 with hose bores DN 20 to DN 40 and G3/4″ to G1.1/2″ threads, each row carrying its O-ring reference code for one-line ordering.
• OEM gate check: full dimensional and material conformance per ISO 12151-6 and ISO 8434-6, with material test reports (MTR) available for every batch.

Core Advantages

1. O-ring positive seal: the elastomer seal gives a forgiving, repeatable joint that is less sensitive to seat surface condition than a plain metal cone, which helps on machines with frequent coupling and uncoupling.
2. Swivel nut, no hose twist: the nut turns independently on the body, so the hose keeps its natural lay and the assembly is not wound up when you tighten the connection.
3. O-ring reference on every part number: each row in the table carries its O-ring code (O171 to O351), so the seal element is ordered with the fitting and never guessed in the workshop.
4. ISO 8434-6 pressure class: the 60° cone end is manufactured and tested per the standard (test practice ISO 19879); the rating for your part number is confirmed on the datasheet.
5. 96 to 1000 h salt spray options: trivalent zinc (96 h), zinc-nickel (720 h), or Dacromet (1000 h), matched to your environment.

Technical Specifications

What Is This BSP Female 60° Cone O-Ring Fitting?

This fitting terminates a braided hose with the O-ring variant of the BSP 60° cone connection. The port end is a swivel nut carrying a BSPP parallel thread (G series, thread form per ISO 228-1). Inside the nut, the fitting body ends in a machined 60° cone, and an O-ring is seated on the cone face. When the nut is tightened onto a male G-threaded stud, the cone centres the joint in the mating cone seat and the O-ring is compressed to form the seal. The G thread is parallel and does not seal by interference; it only pulls and holds the connection. This is why the 60° cone system must never be interchanged with a BSPT taper thread, which seals by thread interference instead.

The O-ring variant is the soft-seal member of the ISO 8434-6 cone family, which the standard defines both with and without O-ring. Where the plain cone version seals metal-to-metal, the O-ring version seals on an elastomer element. That gives two practical differences. First, the joint is more tolerant of small scratches and surface marks on the mating seat, because the O-ring fills the imperfection instead of demanding a perfect cone contact. Second, the service temperature and fluid compatibility of the joint follow the O-ring compound, not the steel, so the compound must be matched to your system. The factory drawing references BS 5200 for this O-ring execution; send us your fluid and operating temperature and our engineers will confirm the compound before shipment.

The 22613-ORW is the large-size member of the O-ring cone line, sharing the body geometry of the 22613-W metal-cone series: the four part numbers in the table cover G3/4″ to G1.1/2″ with hose bores DN 20 to DN 40. The single hexagon S2 on the swivel nut is machined to the standard hex size for the G thread, so service tools are shared with the rest of the BSP range. Use this straight fitting when the hose approaches the port in line with the port axis; it complements the 22641 (45°) and 22691 (90°) elbows on the same cone geometry. Confirm your exact hose construction with our engineers and the matching crimp data sheet is supplied with the order.

Dimensional Data and Threads

Full dimension drawings with A, C, and S2 callouts are supplied as PDF and CAD (STEP/DWG) files. Because this is a crimp fitting, the two process-critical parameters are the hose insert depth and the crimp outside diameter; both are hose-series specific and are listed in the crimp data sheet that accompanies every order.

Full Dimension Table (Part Number Matrix) {#by-thread-size}

Read the table with your BSPP thread (E) and your hose size (dash). The part number is the order code; copy it directly into your inquiry or purchase order. The O-ring code in the same row is the seal element supplied with the fitting. The pattern is 22613-[thread dash]-[hose dash]ORW: for example, 22613-16-16ORW has a G1″ thread and suits a -16 (25 mm) hose.

The dimensions shown are the standard executions of the 22613-ORW series as drawn on the factory specification sheet. If your hose construction needs a different stem profile, a custom BSP female 60° cone fitting is machined on request.

Select by Hose Dash Size {#by-hose-size}

Match your hose bore first, then confirm the thread for that bore:

Material and Heat Treatment

Cold forging preserves the grain flow of the steel, which raises fatigue resistance under pressure pulsation. Each heat-treatment batch is hardness-tested and recorded, so the hardness number on the MTR matches the parts you receive.

Working Pressure

The exact rating for your part number and hose combination is confirmed on the datasheet and by our engineers before shipment.

Pressure-Temperature Operating Envelope

The steel body and cone hold their strength across the full temperature window, but in this O-ring execution the practical service limit is set by the elastomer compound. Confirm the compound for your fluid and temperature range with our engineers, and the fitting will not be the limiting part of the assembly.

Selection and Ordering

The 22613-ORW BSP female 60° cone O-ring fitting series covers the large-bore O-ring segment of BSP hydraulic hose fittings for straight terminations, so most orders can be placed directly from the table above.

BSPP Thread Size Chart

Use this chart to identify the thread on your port. BSPP G threads are parallel; they are identified by measuring the thread outside diameter and counting the threads per inch.

Cross Reference Service {#by-oem-part-number}

Most maintenance teams buy against a legacy part number printed on the old drawing. Send us the OEM or distributor part number you currently use, with a photo of the fitting if possible. Our engineers identify the thread, the cone geometry, the O-ring execution, the hose size, and the body configuration, then confirm the exact 22613-ORW equivalent before you place the order. The service covers 60° cone fittings, BSP hydraulic hose fittings, and BSPP elbows in your inventory, and interchange confirmation is free. The cross reference sheet is returned in PDF for your records.

Assembly and Use Guide

Four-Step Crimping Procedure

1. Cut the hose square: use a hose cutter, never a hacksaw or an angle grinder. A square, clean end is the precondition for a uniform ferrule grip.
2. Mark the insert depth: read the insert depth for your hose series from the crimp data sheet and mark the line on the hose cover.
3. Lubricate and insert: apply a thin film of assembly lubricant to the stem and the hose bore, then push the fitting into the hose until the mark meets the ferrule.
4. Crimp and verify: select the die per the crimp table, crimp in one continuous stroke, then measure the crimp outside diameter with a caliper and compare with the tolerance.

Connecting the O-Ring Cone End

On the BSP female 60° cone O-ring fitting, check that the O-ring is seated correctly in its groove on the cone face and that the ring is clean and undamaged; replace it if cut or flattened. Clean the mating cone seat with a lint-free cloth. Screw the swivel nut onto the male G-threaded stud by hand until the cone face touches the seat, then tighten to the torque listed for the thread size, wrenching the S2 nut hex. The cone centres the joint and the O-ring does the sealing, so no thread sealant is used. The nut swivels on the body, so position the hose routing first and tighten last; the hose will not be twisted by the connection.

Installation Warnings

• ❌ Never mix fittings and ferrules from different suppliers, even when the thread and hose sizes look identical. Stem geometry, ferrule hardness, and crimp parameters differ, and a mixed joint will leak or blow off under pressure.
• ❌ Never confuse G (BSPP parallel) threads with R (BSPT taper) threads. A G thread with a cone seal seals by cone and O-ring contact; a taper thread seals by thread interference and needs sealant. The two are not interchangeable.
• ❌ Never reuse a damaged or hardened O-ring, and never fit a ring of the wrong compound. The O-ring is the sealing element of this joint.
• ❌ Never crimp without the matching crimp data sheet. An under-crimped joint weeps, and an over-crimped joint damages the hose reinforcement.
• ❌ Never recrimp a fitting after a failed attempt, and never reuse a fitting removed from a hose.
• ✔ After assembly, pressure-test the circuit at 1.5x working pressure and inspect all joints for weepage.

Quality and Traceability System

Every batch follows a documented flow: incoming steel with mill certificate → cold forging → CNC machining → heat treatment → plating → O-ring compound verification → 100% thread gauge and dimension inspection → pressure test → laser marking → packing. The batch number on the carton links back to the raw material lot, the heat-treatment record, the O-ring lot, and the inspection report. Material test reports (MTR) are provided with every order on request, and third-party inspection reports (BV/SGS) can be arranged before shipment.

FAQ

Q: What is a BSP female 60° cone O-ring fitting? A: It is a crimp-on fitting for hose whose port end is a swivel nut with a BSPP internal G thread (ISO 228-1); the body ends in a 60° cone with an O-ring seated on the cone face. When the nut is tightened onto a male G-threaded stud, the cone centres the joint and the O-ring seals against the mating seat.

Q: What is the difference between the O-ring version and the plain metal cone version? A: The plain 60° cone version seals metal-to-metal on the cone faces. The O-ring version seals on an elastomer ring, which tolerates small seat surface marks better and is the soft-seal variant defined by ISO 8434-6. The trade-off is that the O-ring compound sets the fluid and temperature limits of the joint.

Q: How does the 22613-ORW compare with the 22613-W series? A: Both share the same large-size body geometry and G3/4″ to G1.1/2″ coverage. The 22613-W is the plain metal-cone execution; the 22613-ORW is the O-ring cone execution referenced to BS 5200 on the factory drawing, with the O-ring code in every part number.

Q: Which O-ring compound should I use? A: The compound must match your fluid and operating temperature. NBR suits mineral oils in standard duty, FKM covers higher temperatures and aggressive fluids, and EPDM suits water and brake-fluid systems. Send us your fluid and temperature and our engineers will confirm the compound before shipment.

Q: Why does the nut swivel, and what does it give me? A: The nut with the internal G thread is captive on the body and rotates freely. You can orient the hose to its natural routing before final torque, and tightening the connection will not twist or wind up the hose assembly.

Q: How does the 22613-ORW compare with the 22641/22691 elbows? A: The 22613-ORW is a straight termination: the hose approaches the port in line with the port axis. The 22641 (45°) and 22691 (90°) are elbows that turn the hose when the port axis and the hose run are not in line. All use the same BSPP 60° cone geometry.

Q: Can you provide crimp data for my hose? A: Yes. Every order includes the crimp data sheet for your hose construction, with insert depth, crimp outside diameter, and die selection. Send us your hose series and brand, and our engineers will confirm the crimp parameters before shipment.
