ORFS Female Hydraulic Hose Fitting: Series 24211

Why This ORFS Female Hydraulic Hose Fitting Passes the Compliance Gate

This ORFS female hydraulic hose fitting (series 24211) is built to the O-ring face seal geometry of SAE J1453 / ISO 8434-3 and crimped to SAE J516 / ISO 12151-1. The female swivel end presses a flat metal face against the mating port face, squeezing an O-ring in the face groove to seal with no tape and no sealant. OEM buyers, hydraulic distributors and repair shops specify series 24211 for leakage-sensitive circuits that need a dependable flat face joint. The complete part-number matrix below covers DN6 through DN40 in one page.

Основные преимущества

• Flat face O-ring seal for high-pressure and vacuum service, with no sealant or thread tape, and a true flat face O-ring hydraulic fitting design.
• Female swivel nut allows the hose to be re-clocked and routed after the joint is torqued.
• Cold-forged carbon steel, heat treated and trivalent zinc plated for a long field life.
• 100% factory pressure test and thread inspection, shipped with batch traceability.

Технические характеристики

What Is an ORFS Female Hydraulic Hose Fitting?

ORFS (O-Ring Face Seal) seals on the flat end faces, not on the threads. An ORFS female hydraulic hose fitting carries a swivel nut, while the mating male end is a flat face with a machined O-ring groove. When the nut is torqued, the two faces meet and the O-ring is compressed, so sealing does not depend on thread interference.

As with all SAE J1453 fittings and ISO 8434-3 fittings, ORFS is not interchangeable with JIC 37 degree (SAE J514), ORB (SAE J1926 / ISO 11926) or SAE 45 degree (SAE J513). To identify an ORFS end, confirm that it is a flat face with an O-ring groove, then measure the thread. ORFS thread sizes usually run about 1/16″ larger than the same JIC size.

Full Dimension Table (Part Number Matrix)

Printed header (bilingual on the sheet): PART NO. | THREAD E | HOSE BORE DN | HOSE BORE DASH | DIMENSIONS A | C | S2. Series 24211 is drawn in three configurations, 24211, 24211-T and 24211-W. Code logic: 24211-<thread dash>-<hose dash>; rows whose part number ends in “T” are the drawing variant marked T. The standard printed on the sheet is ISO 12151-1 – SAE J516.

Note: the printed sheet carries no footnote below the table. Series 24211 is listed for braided-hose applications; for spiral (interlock) hose the family is referenced by series 24213-W. Confirm the exact hose construction with our team before ordering.

Material and Heat Treatment

Рабочее давление и рабочий диапазон

Working pressure is set jointly by the ORFS end connection and the hose grade, so always use the lower of the two ratings. Every fitting is 100% pressure tested at the factory, and torque and crimp data sheets are supplied with each order. Typical service temperature is -40°C to +120°C, and any derating for the system is governed by the hose and the O-ring, not the fitting. Match the fitting series to the hose construction before you finalize a circuit, and confirm the ORFS female hydraulic hose fitting series against the hose grade.

Selection and Ordering

How to Read the Part Number Matrix

Each code follows 24211-<thread dash>-<hose dash>. The first dash is the ORFS thread size and the second is the hose bore. Example: 24211-08-06 uses a 13/16″X16 thread with a -06 hose. Rows ending in “T” are the T-variant shown on the drawing and are ordered with that suffix.

Thread Size and Dash Chart

Cross Reference Service

Send us an OEM drawing or an old part number and we will map it to the closest series 24211 code. We translate thread size, hose dash and end style, then quote a like-for-like replacement. Where the original used a special variant, we confirm the T or W drawing before production. This keeps a retrofit simple even when the incumbent number is not in our catalogue, whether you need a standard ORFS female hydraulic hose fitting or an ORFS female swivel hose fitting.

Packaging and Logistics

Standard packing is 10 pcs per box with a batch box label on every carton. Origin is marked Made in China – HENGHUA, and an MTR is included with the shipment when required. Cartons are palletized for container loading and can be labelled to your own SKU scheme on request. Lead time is confirmed at quotation, with 24-hour response on price and availability for every ORFS female swivel hose fitting order.

Assembly and Use Guide

Four-Step Crimping Procedure

1. Cut the hose square with a cut-off saw and clean any debris from the bore.
2. Mark the insertion depth on the hose cover using the data sheet.
3. Lubricate the hose tail and push the fitting in to the mark without twisting.
4. Crimp to the specified dimension, then verify the crimp OD with a vernier caliper.

Always match the crimp setting to the hose and fitting combination in the data sheet. A wrong setting will not be corrected later by over-torquing the nut.

Connecting the ORFS End

Clean the flat face and check the O-ring before every assembly. Replace the O-ring if it is cut, flattened or hardened, then seat it fully in the groove. Thread the swivel nut on by hand until the faces touch, then torque to the value in the data sheet. The female swivel can be backed off to align the hose without breaking the seal, but never wrap the threads with tape or apply sealant.

Installation Warnings

• Do not mix fittings from different manufacturers on one joint.
• Do not join ORFS to JIC 37 degree, ORB or SAE 45 degree ends.
• Do not reuse or omit the O-ring, and do not install a cut or hardened ring.
• Do not scratch or dent the flat face, since a damaged face will leak.
• Do not crimp without the correct data sheet setting.
• Do use clean faces, a fresh O-ring and the specified torque every time.

OEM Customization and Quality Traceability

Customization Options

We offer laser marking and private labelling, plus custom threads and custom surface finishes. Special O-ring compounds, non-standard lengths and mixed kits can be produced to drawing. Tooling and sampling are quoted per project, with 24-hour response on enquiry.

Quality and Traceability System

Every batch is pressure tested and thread gauged, and each lot carries a batch number traceable through the full production flow. Material test reports are available on request, and third-party inspection by BV or SGS can be arranged. This lets OEM buyers and distributors close their own quality file with confidence.

Часто задаваемые вопросы

What is an ORFS female hydraulic hose fitting? It is a hose end with a female swivel nut that seals on a flat face with an O-ring groove, per SAE J1453 / ISO 8434-3. Series 24211 is the crimped version for braided hose.

How do I tell ORFS from JIC or ORB? Look at the end face: ORFS is flat with an O-ring groove. JIC 37 degree is a cone, and ORB is a straight thread with an O-ring on a boss face. ORFS threads also run about 1/16″ larger than the same JIC size.

Do I need sealant or thread tape? No. The O-ring in the face groove does the sealing, so tape or paste can actually cause a leak. Keep the face clean and torque to the data sheet.

How do I read the thread size? Measure the thread OD and count the threads per inch, then match to the E column, for example 9/16″X18 or 1.3/16″X12.

Can I replace the O-ring? Yes. Use a fresh ring of the correct size and material, seat it fully and inspect the face before reassembly. Never reuse a flattened or hardened ring.

Is there a spiral-hose version? Yes. For spiral (interlock) hose the family is referenced as series 24213-W, and the drawing shows a W configuration. Keep the ORFS female swivel hose fitting on braided hose unless you specify the interlock series. Confirm the hose construction with us before ordering.

Can you customise or private label the fitting? Yes. We offer laser marking, custom threads and custom finishes to your drawing, with 24-hour quotation.
