BSP Female 60° Cone Fitting: 22613-W Series

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

A BSP female 60° cone fitting joins a braided hydraulic hose to a BSPP 60° cone connection: a swivel nut with an internal parallel G thread pulls the fitting’s 60° cone face onto the cone seat of the mating stud, and the two metal faces seal without an O-ring. The 22613-W series from HENGHUA is the large-size heavy-duty execution of this connection, built to ISO 12151-6 for hose fittings with ISO 8434-6 60° cone ends and covering five part numbers from -12 to -32 with G-series parallel threads from G3/4″ to G2″. 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 straight BSP 60° cone termination that carries the big return, pressure, and auxiliary lines on mobile and industrial machines.

• ISO 12151-6 / ISO 8434-6 60° cone geometry: the fitting body ends in a machined 60° cone that seats metal-to-metal against the mating 60° cone seat of the male stud. The G thread is parallel (ISO 228-1) and only holds the connection; the cone does the sealing. No O-ring and no thread sealant are needed at the joint in the standard version.
• Swivel nut design: the drawing shows a single hexagon, S2, on the swivel nut at the port end; the nut is captive on the body behind a retaining ring and rotates freely, so the hose can be oriented before final torque and is never twisted by the connection.
• Large-bore coverage: -12 to -32 with hose bores DN 20 to DN 50 covers the big lines on excavators, loaders, drilling rigs, presses, and plant hydraulics, where 60° cone BSP connections are specified.
• W heavy-duty execution: the W tail profile is the factory’s heavy-duty stem execution for the largest sizes of this family, machined for the reinforcement layers of the matched hose construction.
• 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. 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.
2. ISO 8434-6 pressure class: the 60° cone end is manufactured and tested per the standard (test practice ISO 19879), with heavy (S) class stud ends of this cone geometry rated to the pressure class of the size; the rating for your part number is confirmed on the datasheet.
3. One hex, one wrench: S2 is machined to the standard hex size for the G thread (32 to 70 mm across flats), so service tools are the same ones used across the rest of the BSP range.
4. -40°C to +120°C operating range: the steel cone seal holds across cold-start and hot-running circuits without elastomer ageing at the joint.
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 Fitting?

This fitting terminates a braided hose with the BSP 60° cone connection defined by ISO 8434-6 and used widely across European and Commonwealth hydraulic equipment. 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. When the nut is tightened onto a male G-threaded stud, the 60° cone is drawn into the mating 60° cone seat and the two cone faces meet metal-to-metal. The joint seals by cone contact alone, so no O-ring or thread sealant is used in the standard version. The G thread is parallel and does not seal by interference; it only pulls and holds the connection. This is why a 60° cone seat must never be interchanged with a BSPT taper thread, which seals by thread interference instead.

The 22613-W is the large-size member of the straight BSP 60° cone family. The base 22611 series covers the full spread from G1/8″ to G2″, while the 22613-W line concentrates on the heavy-duty executions from G3/4″ to G2″ with the W tail profile, which is why the -12 to -32 rows of the family appear here with their own part numbers and stem geometry. Where a second wrenching position on the body is needed, the 22611D double hexagon version adds the S1 body hex.

The -W suffix marks the heavy-duty execution on the factory drawing; the five part numbers in the table are the standard executions of the series. Use this straight fitting when the hose approaches the port in line with the port axis. The stem is serrated for a crimped termination; 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 pattern is 22613-[thread dash]-[hose dash]W: for example, 22613-16-16W has a G1″ thread and suits a -16 (25 mm) hose.

The dimensions shown are the standard executions of the 22613-W 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 cone seal and body hold full rated pressure across the whole temperature window. In a crimped assembly the working pressure is governed by the weakest component, normally the hose; use the hose derating curve for the system, and the fitting will not be the limiting part.

Selection and Ordering

The 22613-W BSP female 60° cone fitting series covers the large-bore 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 hose size, and the body configuration, then confirm the exact 22613-W 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 60° Cone End

On the BSP female 60° cone fitting, clean the 60° cone face and the cone seat of the mating stud 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 60° cone contact does the sealing, so no sealant is applied to the cone faces. 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 60° cone seal seals by cone contact; a taper thread seals by thread interference and needs sealant. The two are not interchangeable.
• ❌ 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.
• ❌ Never apply sealant to the 60° cone faces. It hardens, blocks metal-to-metal contact, and contaminates the circuit.
• ✔ After assembly, pressure-test the circuit at 1.5x working pressure and inspect all joints for weepage.

OEM Customization and Quality Traceability

Customization Options

• Size and thread customization: non-standard G thread and hose combinations and special stem lengths machined to your drawing.
• Surface treatment customization: trivalent zinc (96 h), zinc-nickel (720 h), or Dacromet (1000 h) salt spray grades, selected by your environment and corrosion specification.
• Laser marking: your logo, part number, and batch code laser-marked on the hex for full field traceability.
• Material options: 304/316L stainless for chemical, marine, and food-contact circuits, with passivation certificates.

Quality and Traceability System

Every batch follows a documented flow: incoming steel with mill certificate → cold forging → CNC machining → heat treatment → plating → 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, 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 fitting? A: It is a crimp-on fitting for braided hose whose port end is a swivel nut with a BSPP internal G thread (ISO 228-1) plus a body-end 60° cone that seals metal-to-metal against the mating cone seat, per ISO 8434-6 geometry.

Q: What sizes does the 22613-W series cover? A: Five large-bore executions from -12 to -32 (DN 20 to DN 50) with G3/4″ to G2″ threads: 22613-12-12W, 22613-16-16W, 22613-20-20W, 22613-24-24W, and 22613-32-32W.

Q: What is the difference between the 22613-W and the 22611 series? A: Both are straight BSP female 60° cone fittings with the same swivel nut and cone geometry. The 22611 series spans G1/8″ to G2″; the 22613-W is the heavy-duty W-execution line concentrated on the large sizes G3/4″ to G2″ with its own stem geometry and part numbers.

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 60° cone seal? A: When the nut is tightened onto a male G-threaded stud, the fitting’s 60° cone is drawn into the mating 60° cone seat and the two metal faces meet. The G thread is parallel and only holds the connection; the cone does the sealing, so no O-ring or sealant is used in the standard version.

Q: How does the 22613-W compare with the 22641/22691 elbows? A: The 22613-W 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.
