BSP Male 60° Cone Seat Fitting: 12613 Series

Why This BSP Male 60° Cone Seat Fitting Passes the Compliance Gate

A BSP male 60° cone seat fitting terminates a braided hydraulic hose in a male G-threaded stud whose tip carries an internal 60° cone seat. It is the male half of the BSPP 60° cone connection: a female swivel fitting with a 60° cone (as on our 22613-W series) is screwed onto the male thread, and its cone is drawn into this fitting’s cone seat to form a metal-to-metal seal. The 12613 series from HENGHUA is the large-size heavy-duty execution of the male cone seat line, 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 male cone seat termination that carries the big lines on mobile and industrial machines.

• Internal 60° cone seat: the tip of the male thread carries a machined internal (concave) 60° cone seat. When a female swivel 60° cone end is tightened onto the thread, the mating cone seats into this recess and the two metal faces seal without an O-ring.
• BSPP G thread: the thread is parallel (G series, ISO 228-1) and only holds the connection; the cone seat does the sealing. G threads must never be interchanged with BSPT taper threads, which seal by thread interference.
• Wrenching hexagon: the drawing shows one hexagon, S1, between the threaded section and the hose tail, so the fitting can be held firmly while the female nut is torqued against it.
• 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, and pairs size-for-size with the 22613-W female heavy line.
• OEM gate check: full dimensional and material conformance with G thread form per ISO 228-1, with material test reports (MTR) available for every batch.

Core Advantages

1. The cone seat side of the large-bore joint: if your big lines mate female swivel 60° cone ends, this fitting provides the matching male thread and cone seat in the heavy size range.
2. Metal-to-metal cone seal: the cone-to-seat contact seals without washers or O-rings in the standard version, removing a soft element from the pressure path.
3. Five part numbers cover the big lines: G3/4″ to G2″ with DN 20 to DN 50 hose bores, matched to the 22613-W female executions.
4. Single hexagon for installation: the S1 hex sits between thread and tail, giving a solid wrenching point when you tighten the mating female nut.
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 Male 60° Cone Seat Fitting?

This BSP male 60° cone seat fitting terminates a braided hose in the male stud side of the BSP 60° cone connection. The port end is a male parallel G thread (G series, thread form per ISO 228-1); at the tip of the thread, the fitting carries a machined internal (concave) 60° cone seat. The other end is a serrated hose tail that is crimped onto the hose. When a female swivel fitting with a 60° cone is tightened onto the male thread, the mating cone is drawn into this fitting’s internal cone seat and the two metal faces meet in a metal-to-metal seal. The G thread is parallel and does not seal by interference; it only pulls the cone into the seat. This is why a 60° cone seat must never be paired with a BSPT taper thread, which seals by thread interference instead.

The 12613 is the large-size member of the male cone seat family. The base 12611 series covers the full spread from G1/8″ to G2″, while the 12613 line concentrates on the heavy-duty executions from G3/4″ to G2″ with its own stem geometry and part numbers. The 12613 male line pairs size-for-size with the 22613-W female heavy line in the same catalog: when you build a big hose assembly with a 22613-W female end, the matching 12613 male end carries the stud side of the next joint. Buying both halves from the same catalog means the cone geometry, thread sizes, and seal faces are matched by design.

Use this male fitting when the mating component is a female swivel 60° cone end. The single hexagon S1 sits between the threaded section and the hose tail, giving a firm wrenching point while the female nut is torqued. The serrated hose tail is engineered 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 S1 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 12613-[thread dash]-[hose dash]: for example, 12613-16-16 has a G1″ thread and suits a -16 (25 mm) hose.

The dimensions shown are the standard executions of the 12613 series as drawn on the factory specification sheet. If your hose construction needs a different stem profile, a custom BSP male 60° cone seat 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 seat 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 12613 BSP male 60° cone seat fitting series covers the large-bore male 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 seat geometry, the hose size, and the body configuration, then confirm the exact 12613 equivalent before you place the order. The service covers 60° cone fittings, BSP hydraulic hose fittings, and the male stud ends of your inventory, and interchange confirmation is free. The cross reference sheet is returned in PDF for your records.

Packaging and Logistics

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 Seat End

On the BSP male 60° cone seat fitting, clean the internal cone seat and the cone of the mating female swivel fitting with a lint-free cloth. Hold the S1 hexagon with a wrench and thread the female nut onto the male G thread by hand until the cone touches the seat, then tighten to the torque listed for the thread size. The 60° cone contact does the sealing, so no sealant is applied to the cone faces. If your circuit uses the O-ring variant of the 60° cone family, fit the correct O-ring before assembly; do not mix the O-ring and plain cone versions.

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 seat seals by cone contact; a taper thread seals by thread interference and needs sealant. The two are not interchangeable.
• ❌ Never match a cone seat to a scratched or pitted mating cone. The metal-to-metal seal needs an undamaged sealing surface on both sides.
• ❌ 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.

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 male 60° cone seat fitting? A: It is a crimp-on fitting for hose whose port end is a male parallel G thread (ISO 228-1); the tip of the thread carries an internal 60° cone seat that receives the cone of a female swivel 60° cone end.

Q: How does the connection seal? A: A female swivel fitting with a 60° cone is screwed onto the male thread, and the cone is drawn into the internal cone seat. The two metal faces meet in a metal-to-metal seal; the G thread only holds the connection.

Q: What is the difference between the 12613 and the 12611 series? A: Both are male BSPP 60° cone seat fittings with the same thread and cone geometry. The 12611 series spans G1/8″ to G2″; the 12613 is the heavy-duty execution line concentrated on the large sizes G3/4″ to G2″ with its own stem geometry and part numbers.

Q: How does the 12613 pair with the 22613-W female series? A: The 22613-W female swivel fittings carry the nut with the internal G thread and the convex cone. The 12613 male fittings carry the external G thread and the concave cone seat that receives it. The two are the matching halves of the same large-size heavy joint.

Q: Which hoses work with the 12613 series? A: The part numbers in the table suit braided hose from -12 to -32 (DN 20 to DN 50). Confirm your exact hose construction with our engineers, and the matching crimp data sheet will be supplied with the order.

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.
