Metric Male 24 Degree Cone Seat Fitting Technical Specifications

The table below lists all 18 sizes of the 10411-RW metric male 24 degree cone seat fitting. Dimensions are in millimeters. All threads are metric fine (ISO 725 based) with a 24 degree inner cone seat per DIN 3865.

Notes: Dim. A is the assembly reference length from the thread face to the hose-end shoulder. Dim. C is the thread zone length. Hex S1 is the wrench size across flats. The -RW suffix denotes the braided-hose version; for spiral-wound hose, use series 10412-XX-XXRW.

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

For this metric male 24 degree cone seat fitting, insert depth is the length of the barbed tail that enters the hose bore. It determines how much grip the crimped ferrule zone has on the hose reinforcement. Crimp O.D. is the outside diameter of the ferrule after crimping. It is the single most important process control value for a leak-free assembly.

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. Never rely on feel or visual judgment. 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 seat 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 for corrosion resistance. 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, chemical lines and food-grade washdown systems. Stainless versions are supplied with a clean, pickled surface.

Pressure and Temperature Ratings

The connection rating follows the DIN 2353 light series 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 DIN 2353 light series. 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 Metric Male 24 Degree Cone Seat Fitting

Selection is a three-step process. First, match the hose bore to the dash size. Second, match the thread to your port. Third, confirm the hose construction version (-RW for braided, 10412 series for spiral).

Part Number Structure

Read any HENGHUA part number in three segments. Example: 10411-22-08RW.

Select by Hose Series

The 10411-RW fitting is designed for braided hydraulic hose. Recommended matching constructions:

• SAE 100 R1AT (one wire braid) – for -04 to -24 sizes
• SAE 100 R2AT (two wire braid) – for -04 to -24 sizes
• EN 853 1SN and 2SN (equivalent European constructions)
• DIN EN 857 1SC and 2SC (compact constructions, confirm insert depth)

Select by Thread Size

The 24 degree cone seat accepts the 24 degree outer cone of the mating connector. All threads are metric fine:

• Small sizes: M12x1.5, M14x1.5, M16x1.5, M18x1.5 (dash -04 to -06)
• Medium sizes: M22x1.5, M26x1.5, M27x1.5, M30x2 (dash -06 to -12)
• Large sizes: M36x2, M45x2, M52x2 (dash -16 to -24)

Tightening is via the hex S1 with a standard wrench. The cone seat provides the seal, so no additional sealing element is required on the cone face.

Assembly Guide: Four Steps to a Safe Hose Assembly

Follow this process for every crimped assembly. It applies to every metric male 24 degree cone seat fitting size from dash -04 to -24. 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. A correct crimp O.D. is the difference between a 10-year assembly and a field failure.

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. Mixing brands voids any performance claim.
• Never seal the 24 degree cone with tape. The cone seat seals by metal-to-metal 24 degree cone contact. Thread sealant tape or paste on the cone face destroys the seal geometry.
• Tapered threads need sealant. When this fitting is adapted to a tapered thread port (NPT or BSPT), the adapter requires thread sealant. Parallel thread connections with O-ring seals must never receive tape. Do not confuse the two sealing methods.
• Tighten to spec. Use the hex S1 and tighten to the torque value on the data sheet. Over-tightening distorts the cone seat. 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.
