14211-RW ORFS Male O-Ring Seal Fitting

Our ORFS male O-ring seal fitting, series 14211-RW, is a crimp-on hydraulic hose fitting built to the American ORFS (O-Ring Face Seal) system, with a UNF male thread and an O-ring groove at the thread tip. It connects braided hydraulic hose to ORFS male ports on pumps, valves and cylinders made to SAE J1453. The range covers 9/16″-18 to 2″-12 UNF threads, dash size -04 to -24, hose bore DN6 to DN40. Every fitting ships with its matched O-ring and is 100% dimensionally inspected before packing.

Compliance and standards:

• SAE J1453 (O-ring face seal / ORFS system)
• ISO 8434-3 (O-ring face seal connectors)
• UNF threads (Unified National Fine, inch based)
• SAE J516 (general hydraulic hose fitting design reference)

Why buyers choose this fitting:

• Zero-leak face seal. The O-ring sits in the groove at the thread tip and seals against the flat face of the mating port. No metal-to-metal fit-up required, no leakage under impulse pressure.
• The leak-free American standard. ORFS is the preferred connection for high pressure, high impulse and mobile hydraulic applications where JIC connections weep.
• O-ring included with every fitting. Every 14211-RW fitting ships with the matched O-ring pre-installed. No tape, no paste, no guesswork at assembly.
• Full UNF thread range. 9/16″-18 through 2″-12, covering the complete SAE J1453 dash grid from -04 to -24.

ORFS Male O-Ring Seal Fitting Technical Specifications

The table below lists all 15 sizes of the 14211-RW ORFS male O-ring seal fitting. Dimensions are in millimeters. All threads are UNF (Unified National Fine) with an O-ring groove at the thread tip per SAE J1453.

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. O-ring sizes follow the SAE J1453 O-ring designation (O011 through O029). The -RW suffix denotes the braided-hose version; for spiral-wound hose, use series 14212-XX-XXRW.

How the ORFS Face Seal Works – and Why It Does Not Leak

The ORFS connection seals differently from every cone-type fitting in our catalog. Instead of a metal cone, the ORFS male fitting carries a groove at the thread tip with an O-ring. When the UNF thread is tightened, the O-ring is compressed between the flat face of this fitting and the flat face of the mating port. The O-ring, not metal, carries the seal.

This design gives three advantages that matter in the field. First, it tolerates surface scratches and minor nicks on the port face, where a cone or flare seal would start to weep. Second, it withstands high impulse pressure without loosening, because there is no cone to embed. Third, it can be repeatedly assembled and disassembled with a simple O-ring replacement. Our impulse testing found that ORFS assemblies hold pressure cycling significantly longer than equivalent JIC flare assemblies of the same size.

ORFS vs JIC – Which One Do You Need

JIC (37 degree flare) is the classic American connection, economical and widely available. ORFS is the upgrade: the O-ring face seal eliminates the metal-to-metal fit-up that causes JIC weeping under high impulse and high pressure.

Choose ORFS when the circuit runs at high pressure with sharp pressure spikes, such as pump discharge lines, pressure washing equipment and mobile hydraulic systems. Choose JIC when the application is standard pressure and cost matters most. This fitting is the ORFS male end; the matching female side is our 14221 series ORFS female 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 O-ring groove 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.
• O-ring elastomer: standard NBR (nitrile). FKM, EPDM and other elastomers are available on request for special fluids and temperatures.

Pressure and Temperature Ratings

The connection rating follows the SAE J1453 O-ring face seal 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 SAE J1453 O-ring face seal connection classes. Confirm the assembly rating with the HENGHUA crimp data sheet matched to your hose.

Temperature range: -40°C to +100°C with the standard NBR O-ring. At elevated temperature, apply the standard SAE J517 style derating to the assembly working pressure. The O-ring operating range can be extended with FKM material for high-temperature circuits.

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 ORFS Male O-Ring Seal Fitting

Selection is a three-step process. First, match the hose bore to the dash size. Second, match the UNF thread to your port. Third, confirm the hose construction version (-RW for braided, 14212 series for spiral).

Part Number Structure

Read any HENGHUA part number in three segments. Example: 14211-08-08RW.

Select by Hose Series

The 14211-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)

Select by Thread Size

The O-ring at the thread tip seals against the flat face of the mating ORFS port. All threads are UNF (Unified National Fine):

• Small sizes: 9/16″-18, 11/16″-16, 13/16″-16 (dash -04 to -08)
• Medium sizes: 1″-14, 1.3/16″-12 (dash -08 to -12)
• Large sizes: 1.7/16″-12, 1.11/16″-12, 2″-12 (dash -12 to -24)

Tightening is via the hex S1 with a standard wrench. The O-ring is pre-installed, so assembly is a simple screw-on operation.

Packaging and Logistics

Assembly Guide: Four Steps to a Safe Hose Assembly

Follow this process for every crimped assembly. It applies to every ORFS male O-ring seal 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.
• Never seal the ORFS face with tape. The O-ring carries the seal. Thread sealant tape or paste on the face or thread damages the O-ring and destroys the seal.
• Check the O-ring before assembly. A cut, pinched or hardened O-ring must be replaced. The O-ring is the sealing element; never assemble without it.
• Do not confuse ORFS with JIC. ORFS uses a flat face with an O-ring; JIC uses a 37 degree flare cone. The threads may be similar, but the sealing geometry is completely different.
• Tighten to spec. Use the hex S1 and tighten to the torque value on the data sheet. Over-tightening distorts the face. Under-tightening causes the O-ring to leak.
• 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 an ORFS male O-ring seal fitting?

It is a hydraulic fitting with a UNF male thread and an O-ring groove at the thread tip. The O-ring seals against the flat face of the mating port. The system follows SAE J1453 and ISO 8434-3.

Why does ORFS leak less than JIC?

ORFS seals with a compressed O-ring against a flat face, which tolerates scratches and surface imperfections. JIC seals with metal-to-metal 37 degree flare contact, which can weep under high impulse pressure. ORFS is the preferred connection for zero-leak requirements.

Is the O-ring included?

Yes. Every 14211-RW fitting ships with the matching O-ring pre-installed in the groove. Spare O-rings can be ordered by the size code listed in the specification table.
