One-Piece ORFS Hydraulic Hose Fitting: Series 24211-RW

Why This One-Piece ORFS Hydraulic Hose Fitting Passes the Compliance Gate

This one-piece ORFS hydraulic hose fitting (series 24211-RW) uses an ORFS female flat face end with the O-ring face seal geometry of SAE J1453 / ISO 8434-3, crimped to SAE J516 / ISO 12151-1. One-piece construction means the swivel nut and hose tail are formed as a single body, so there is no separate stem joint to leak or fatigue. OEM buyers, hydraulic distributors and repair shops choose series 24211-RW for high-pressure and impulse-cycled circuits. The matrix below covers 27 part numbers from DN6 to DN40.

主な強み

• One-piece body removes the stem joint, cutting leak paths and improving impulse life, the key benefit of an ORFS one-piece crimp fitting.
• Flat face O-ring seal needs no tape or sealant and holds in high-pressure service.
• Female swivel nut allows the hose to be re-clocked after the joint is tightened.
• Cold-forged carbon steel, heat treated and trivalent zinc plated, 100% pressure tested.

技術仕様

What Is a One-Piece ORFS Hydraulic Hose Fitting?

A one-piece ORFS hydraulic hose fitting is made as a single forged body that combines the hose tail and the ORFS female swivel nut. Crimping the tail onto the hose forms the joint directly in the body, so the assembly has fewer interfaces than a two-piece design.

The ORFS end still seals at the flat faces. The mating male end carries an O-ring in its face groove, and torquing the swivel nut compresses the ring between the two flat faces. This O-ring face seal is not interchangeable with JIC 37 degree (SAE J514), ORB (SAE J1926 / ISO 11926) or SAE 45 degree (SAE J513).

寸法データ

全寸法表（部品番号マトリックス）

Printed header (bilingual on the sheet): PART NO. | THREAD E | HOSE BORE DN | HOSE BORE DASH | DIMENSIONS A | C | S2. Series 24211-RW is drawn as 24211-RW and 24211-TRW. Code logic: 24211-<thread dash>-<hose dash>RW; a “T” before the RW marks the drawing variant T, and the “W” variant appears on the largest sizes. The standard printed on the sheet is ISO 12151-1 – SAE J516.

Note (printed footnote): 1. For use with braided hoses. 2. If use with spiral hoses, change the hose fitting series number to 24212-XX-XXRW.

材料および熱処理

使用圧力および動作範囲

Working pressure is set jointly by the ORFS end connection and the hose grade, so always use the lower of the two ratings. The one-piece body is well suited to impulse-cycled circuits because it has no separate stem joint. 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 is governed by the hose and the O-ring.

選定と発注

部品番号マトリックスの読み方

Each code follows 24211-<thread dash>-<hose dash>RW. The “RW” marks the one-piece body. A “T” before the RW is the T-variant shown on the drawing, and a “W” is the W-variant. Example: 24211-08-08RW uses a 13/16″X16 thread with a -08 hose.

相互参照サービス

Send us an OEM drawing or an old part number and we will map it to the closest one-piece ORFS hydraulic hose fitting 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 makes a drop-in retrofit simple even when the incumbent number is not in our catalogue.

包装・物流

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 one-piece crimp fitting order.

組み立て・使用ガイド

4段階の圧着手順

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.

For a one-piece ORFS hydraulic hose fitting the crimp is formed straight onto the fitting body, so the dimension in the data sheet must be followed exactly. Never compensate a poor crimp by over-torquing the swivel 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.

インストールに関する注意事項

• 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 the one-piece ORFS hydraulic hose fitting without the correct data sheet setting.
• Do use clean faces, a fresh O-ring and the specified torque every time.

OEMカスタマイズと品質トレーサビリティ

カスタマイズオプション

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.

品質およびトレーサビリティ体制

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.

よくある質問

What is a one-piece ORFS hydraulic hose fitting? It is an ORFS female hose end whose swivel nut and hose tail are forged as one body. Crimping forms the joint directly in the body, so there is no separate stem joint to leak.

How is it different from the two-piece 24211 series? The two-piece 24211 uses a separate stem under a crimped nut, while series 24211-RW is a single forged ORFS one-piece crimp fitting. The one-piece design has fewer interfaces and better impulse resistance.

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.

What does the T or W in the part number mean? They mark drawing variants shown on the sheet, for example 24211-08-05TRW or 24211-20-20WRW. Always order with the exact suffix printed on the drawing.

Can I use it on spiral hose? The printed note states the code is for braided hose, and for spiral hose the series becomes 24212-XX-XXRW. 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.
