22641-RW 45 Degree BSP Female 60 Degree Cone Fitting

Our 45 degree BSP female 60 degree cone fitting, series 22641-RW, is a one-piece crimp-on elbow that connects braided hydraulic hose to BSP female ports at a fixed 45 degree angle, with a 60 degree outer cone end and a BSP parallel (G) thread. It is built to the British standard sealing system, where the metal cone carries the seal. The range covers G1/4″ to G2″ threads, dash size -04 to -32, hose bore DN6 to DN50. Every elbow is formed in one piece, without welding, and 100% dimensionally inspected before shipment.

Compliance and standards:

• BS 5200 (BSP 60 degree cone sealing system)
• ISO 8434-6 (60 degree cone connectors with BSP threads)
• BSP parallel threads (G series, ISO 228 based)
• SAE J516 (general hydraulic hose fitting design reference)

Why buyers choose this elbow:

• One-piece 45 degree elbow. Formed from a single forging or cold-headed blank. No weld at the bend, no weak point under impulse pressure.
• 60 degree outer cone end. The cone end mates into the 60 degree cone seat of the receiving port. Metal-to-metal cone contact carries the seal, exactly as the British standard intends.
• Full British port coverage. G1/4″ through G2″ covers the complete BSP female port grid, including the large G1.1/2″ and G2″ sizes.
• Wide temperature range. Rated for -40°C to +100°C continuous duty, verified in our production line tests.

45 Degree BSP Female 60 Degree Cone Fitting Technical Specifications

The table below lists all 17 sizes of the 22641-RW 45 degree BSP female 60 degree cone fitting. Dimensions are in millimeters. All threads are BSP parallel (G series, ISO 228 based) with a 60 degree outer cone end. Dim. A is the horizontal distance from the elbow axis to the hose-end shoulder, Dim. H is the height from the elbow axis to the nut face, Dim. C is the cone zone length, and S2 is the wrench size across flats.

*Row 22641-20-16TRW: the A and H values read slightly below the 16-16RW row in the scanned source. Confirm these dimensions against the original HENGHUA spec sheet before large orders.

Notes: The -RW suffix denotes the braided-hose version; for spiral-wound hose, use series 22642-XX-XXRW. The 22641 series is the 45 degree elbow counterpart of the 22611D straight BSP female fitting.

Why a One-Piece 45 Degree Elbow

A 45 degree outlet is the preferred routing angle where a hose must change direction without a sharp 90 degree turn. This 45 degree BSP female 60 degree cone fitting replaces a straight fitting plus a separate elbow adapter, removing two potential leak points and extra length.

The elbow body is formed in one piece by hot forging or cold heading, then machined to tolerance. There is no welded seam at the bend. Our impulse testing found that a one-piece elbow survives pressure cycling significantly longer than a welded two-piece elbow of the same size. The 45 degree outlet also keeps the hose away from sharp edges on the machine frame, which reduces cover wear and extends hose life.

How the 60 Degree Cone End Seals

This fitting carries a 60 degree outer cone at the threaded end. When the BSP parallel thread (G) is tightened into a port with a matching 60 degree cone seat, the cone end seats into the cone and the metal-to-metal contact carries the seal. The thread itself only positions and tightens the connection.

This is the classic British sealing philosophy: a metal cone joint that tolerates repeated assembly and disassembly without replacing a sealing element. There is no O-ring, no bonded washer and no thread sealant on the cone. Keep the cone surface clean and undamaged, and the seal repeats every time. The matching receiving side is our 12611 series BSP male 60 degree cone seat fitting.

Insert Depth and Crimp O.D. – The Two Numbers Engineers Ask For

Insert depth is the length of the barbed tail that enters the hose bore. Crimp O.D. is the outside diameter of the ferrule after crimping. Together they decide whether the assembly holds pressure or leaks at the crimp zone.

HENGHUA publishes the matched insert depth and crimp O.D. for every hose construction we supply, including SAE 100 R1AT, R2AT and EN 853 1SN / 2SN. The values are hose-specific because reinforcement thickness changes the stack-up. Request our crimp data sheet with your hose model and we will return the exact crimp O.D. and die selection within one working day.

Our production testing found that a verified crimp O.D. within the published tolerance (typically +/- 0.2 mm) gives a burst safety margin of 4:1 or higher on the complete assembly. Measure with a digital caliper after every crimp.

Material and Heat Treatment

• Carbon steel (standard): high-strength cold-headed or hot-forged carbon steel (20# / 35# / 45# grades). The tail and cone are case-hardened with a carburizing and quenching process for fatigue resistance. Reference hardness range is HRC 20-28 on the core with a hardened case.
• Surface finish: white zinc or color (yellow) zinc plating with passivation. Optional zinc-nickel and Dacromet coatings are available for higher salt spray requirements.
• Stainless steel (option): 304, 316 or 316L stainless steel for corrosive media and washdown environments.

Pressure and Temperature Ratings

The connection rating follows the BSP 60 degree cone sealing system reference table below. These are reference values (§) for the fitting connection itself. The final working pressure of a hose assembly is set by the hose construction and the approved crimping specification.

§Reference values per the BSP 60 degree cone system (BS 5200 class). Confirm the assembly rating with the HENGHUA crimp data sheet matched to your hose.

Temperature range: -40°C to +100°C for the fitting in continuous service. At elevated temperature, apply the standard SAE J517 style derating to the assembly working pressure. Our technical data sheet includes a pressure-temperature derating chart; contact us and we will send it with your quotation.

Pressure testing: HENGHUA can supply assemblies proof-tested up to 100% of the rated working pressure, with test certificates on request.

How to Select the Right 45 Degree BSP Female 60 Degree Cone Fitting

Selection is a four-step process. First, confirm the port needs a 45 degree outlet. Second, match the hose bore to the dash size. Third, match the G thread to your port. Fourth, confirm the hose construction version (-RW for braided, 22642 series for spiral).

Part Number Structure

Read any HENGHUA part number in three segments. Example: 22641-12-12RW.

Select by Hose Series

The 22641-RW elbow is designed for braided hydraulic hose. Recommended matching constructions:

• SAE 100 R1AT (one wire braid) – for -04 to -32 sizes
• SAE 100 R2AT (two wire braid) – for -04 to -32 sizes
• EN 853 1SN and 2SN (equivalent European constructions)

Select by Thread Size

The 60 degree outer cone end mates into a 60 degree cone seat. All threads are BSP parallel (G series):

• Small sizes: G1/4″, G3/8″ (dash -04 to -06)
• Medium sizes: G1/2″, G5/8″, G3/4″ (dash -06 to -12)
• Large sizes: G1″, G1.1/4″, G1.1/2″, G2″ (dash -12 to -32)

The nut rotates freely before tightening, which lets you align the 45 degree outlet in any direction around the port axis.

45 Degree vs Straight vs 90 Degree – Which One Do You Need

Use a straight fitting when the hose leaves the port in line with the port axis. Use a 45 degree elbow when the hose must change direction but a 90 degree elbow would create too sharp a bend. Use a 90 degree elbow when the hose must turn immediately. When in doubt, send us a sketch of your routing and our engineers will confirm the correct angle and size within one working day.

Assembly Guide: Four Steps to a Safe Hose Assembly

Follow this process for every crimped assembly. It applies to every 45 degree BSP female 60 degree cone fitting size from dash -04 to -32. Skipping one step is the most common cause of early fitting failure.

Step 1 – Cut the hose square. Use a sharp hose cutter. A square cut face lets the fitting seat evenly inside the hose. A beveled or ragged cut leaves voids that become leak paths.

Step 2 – Mark the insert depth. Measure the insert depth from the HENGHUA crimp data sheet. Mark a line on the hose cover at that distance. The mark must remain visible after insertion.

Step 3 – Lubricate and insert. Apply a thin layer of compatible assembly lubricant to the hose bore and the barbed tail. Push the fitting in with a twisting motion until the depth mark aligns with the tail end. Stop at the mark. Do not force past it.

Step 4 – Crimp and verify. Select the correct die set for your hose and fitting size. Crimp in one continuous stroke. After crimping, measure the crimp O.D. with a digital caliper and compare it with the tolerance on the crimp data sheet. Record the value on your quality log. Then align the nut and tighten it to the torque value on the data sheet.

Safety Warnings – Read Before Crimping

• Never mix brands. Hoses and fittings from different manufacturers may share the same dimensions but use different crimp parameters. Always use a matched hose, fitting and crimp data sheet.
• Never seal the 60 degree cone with tape. The cone end seals by metal-to-metal 60 degree cone contact. Thread sealant tape or paste on the cone surface destroys the seal geometry.
• Do not confuse G threads with R threads. BSP parallel (G) threads seal at the cone. BSP taper (R) threads seal on the thread itself and need sealant. Never mix the two systems.
• Align the nut before final tightening. Rotate the 45 degree outlet to its final direction, then tighten. Do not use the hose to twist the nut into position after tightening.
• Tighten to spec. Tighten to the torque value on the data sheet. Over-tightening distorts the cone. Under-tightening causes vibration loosening.
• Never reuse a crimped fitting. Once crimped, the ferrule zone is work-hardened. A re-crimp cannot restore the original grip.

Frequently Asked Questions

What is a 45 degree BSP female 60 degree cone fitting?

It is a one-piece elbow fitting with a BSP parallel (G) female thread and a 60 degree outer cone end. The cone mates into a 60 degree cone seat and seals by metal-to-metal contact. The 45 degree outlet redirects the hose at a shallow angle to the port axis.

Why choose a 45 degree elbow instead of a straight fitting?

A 45 degree elbow removes the need for a separate elbow adapter, saves routing space, and keeps the hose bend radius within safe limits. It is the best choice when the hose must leave the port at a shallow angle.

What is the difference between BSP parallel and BSP taper?

BSP parallel (G) threads are straight and seal at the cone. BSP taper (R) threads are tapered and seal on the thread flank itself with sealant. This fitting is the parallel cone-seal type.

Which hose works with the 22641-RW fitting?

The 22641-RW version is designed for braided hydraulic hose such as SAE 100 R1AT, R2AT and EN 853 1SN / 2SN. For spiral-wound hose, use the 22642 series.

Do you supply stainless steel versions?

Yes. 304, 316 and 316L stainless steel versions are available for the full size range, with the same dimensions and crimp behavior.

What is the minimum order quantity?

Stock sizes start from 100 pcs. Customized versions start from 500 pcs per size. OEM annual contracts can be discussed directly with our factory team.
