45 Degree ORFS Elbow Hydraulic Hose Fitting: 24241 Series

Why This 45 Degree ORFS Female Elbow Fitting Passes the Compliance Gate

The 24241 series is a 45 degree ORFS elbow hydraulic hose fitting engineered for O-ring face seal circuits where routing space is tight and a straight fitting will not clear. The flat face and captured O-ring seal metal to metal on the port face, so the joint holds under vibration and pressure cycling without thread sealant. OEM engineers, distributors, and repair shops use the series to replace worn elbows and to standardize assemblies across braided and spiral hose builds. Every shipment travels with heat-number traceability and a 100% pressure test record.

主な強み

• Tight-radius 45 degree routing: the bent body solves clearance problems without forcing a hose bend beyond its minimum radius.
• O-ring face seal reliability: a machined flat face and elastomer O-ring deliver repeatable, weep-free sealing on SAE J1453 and ISO 8434-3 ports.
• Wide thread and dash coverage: twenty-six catalog part numbers cover 9/16″X18 through 2″X12 threads and -04 through -24 hose dashes.
• Braided and spiral readiness: the same body is offered under the 24242-XX-XX code for spiral (interlock) hose assemblies.
• Traceable quality: batch numbers, material certificates on request, and third-party inspection available per order.

技術仕様

What Is an ORFS Female Hydraulic Hose Fitting?

ORFS stands for O-Ring Face Seal, a flat-face connection standardized as SAE J1453 and ISO 8434-3. Sealing happens when a flat metal face on the fitting presses against the flat port face, compressing an O-ring seated in the face groove; there is no 37 degree cone. Because the nut is free to spin on the fitting body, installers can index the elbow and then torque it to spec. The sealing surface must stay clean and scratch-free, and the O-ring must be intact and correctly sized.

A 45 degree ORFS elbow hydraulic hose fitting like the 24241 directs flow at a diagonal angle to ease plumbing around valves, manifolds, and frames. Threads run one to two sixteenths larger than an equivalent JIC 37 degree flare, so an ORFS nut will not thread onto a JIC seat. This family is not interchangeable with ORB (SAE J1926), JIC 37 degree (SAE J514), or SAE 45 degree (SAE J513); confirm the flat face and the O-ring groove before ordering.

寸法データ

Dimensions for this 45 degree ORFS elbow hydraulic hose fitting follow the drawing for the 24241, 24241-T, and 24241-W variants. Where a symbol has no printed note, treat the value as dimensioned on the drawing.

The 24241 drawing lists A, H, E, S2; the 24241-T drawing lists the same set; the 24241-W drawing adds the C dimension. Values are read directly from the specification drawing.

全寸法表（部品番号マトリックス）

All part numbers below for this 45 degree ORFS elbow hydraulic hose fitting are for braided hose. Read each code as series-thread dash-hose dash: 24241-08-08 is the 13/16″X16 thread body crimped to a -08 hose. Thread E, hose bore DN, dash size, and dimensions A, H, C, and S2 are transcribed exactly as printed.

Drawing notes (transcribed): (1) the part numbers in the table are for braided hose; (2) for spiral hose, change the code to 24242-XX-XX. Part-number suffixes -T and -W appear as printed on the drawing for the corresponding body variants.

材料および熱処理

使用圧力および動作範囲

Rated pressure is set by the end connection standard and the hose rating together, not by the fitting alone; always use the lower of the two. Every 45 degree ORFS elbow hydraulic hose fitting in the series is 100% factory pressure tested, and a torque and crimp data sheet for the exact part number is supplied with each order. Typical service temperature is -40 degree C to +120 degree C, and the system must be derated for extremes according to the hose and seal selected. Confirm the working pressure of the assembled hose before commissioning.

選定と発注

部品番号マトリックスの読み方

When specifying a 45 degree ORFS elbow hydraulic hose fitting, pick the ORFS thread E first, then the hose dash that matches your hose bore. The trailing dash in the part number is the hose dash: 24241-10-12 couples a 1″X14 ORFS female end to a -12 hose. Interpolation between listed thread and dash combinations is not permitted without engineering review. For spiral hose, order the same size under the 24242-XX-XX code.

ねじサイズとダッシュ表

相互参照サービス

Send us a photo of the old fitting, the OE part number, or the thread measurement and we will map it to the closest 24241 size. Our team translates legacy and OEM part numbers into the standard HENGHUA code, and flags any case where a 45 degree body cannot replace the original angle. Turnaround on cross-reference requests is typically within 24 hours.

包装・物流

Every 45 degree ORFS elbow hydraulic hose fitting ships at 10 pcs per box with batch box labels. Cartons carry the country of origin as Made in China, HENGHUA, and each box lists the batch number for traceability. Material test reports travel with the shipment, and third-party inspection can be arranged before dispatch. Custom carton printing and private labeling are available for volume orders.

組み立て・使用ガイド

4段階の圧着手順

1. Cut square: cut the hose perpendicular with a fine-tooth saw and blow out debris.
2. Mark insert depth: mark the insertion depth on the hose cover using the fitting as a gauge.
3. Lubricate and insert: apply compatible lubricant and push the hose fully onto the insert until it bottoms.
4. Crimp and verify: crimp with the correct die, then measure the crimped outside diameter with a caliper against the data sheet.

Connecting the ORFS End

Clean the flat face and the port face of all oil, grit, and paint before assembly. Inspect the O-ring for cuts or swelling and replace it if damaged; never reuse a hardened or nicked O-ring. Hand-thread the swivel nut until it seats, then torque it to the value in the supplied data sheet. Because the nut spins freely, index the 45 degree body to the routing you need, then hold it while torquing. Do not wrap the threads with PTFE tape or apply sealant.

インストールに関する注意事項

• ❌ Never mix an ORFS flat-face fitting with JIC 37 degree, ORB, or SAE 45 degree seats.
• ❌ Never install without a correct, undamaged O-ring in the face groove.
• ❌ Never reuse an O-ring that is compressed, cut, or aged.
• ❌ Never scratch, dent, or paint the flat sealing face.
• ❌ Never crimp without the part-specific crimp data sheet.
• ✔ Do clean both faces, verify the O-ring, and torque to the published value.

OEMカスタマイズと品質トレーサビリティ

よくある質問

What is an ORFS fitting? ORFS means O-Ring Face Seal, a flat-face connection per SAE J1453 and ISO 8434-3. A flat metal face compresses an O-ring into the port face to seal without tape or sealant.

How do I tell ORFS apart from JIC or ORB? Look for the flat face with an O-ring groove; JIC 37 degree has a cone and ORB uses a straight thread with an O-ring at the boss. ORFS threads also run about one sixteenth larger than the same-size JIC thread.

Do I need sealant on the threads? No. The seal is made at the flat face by the O-ring, so PTFE tape or thread sealant is unnecessary and can contaminate the system.

Can I reuse the O-ring? Only if it is soft, clean, and free of cuts. Replace any O-ring that is hardened, flattened, or nicked to avoid a leak.

What is the difference between the braided and spiral versions? The listed 24241 part numbers are for braided hose; for spiral (interlock) hose the code changes to 24242-XX-XX while the sealing face and thread stay the same.

Can the 45 degree angle be customized? Fixed 45 degree bodies are standard, and our engineering team can quote alternative angles or dimensions against your drawing.

How do I order a 45 degree ORFS elbow hydraulic hose fitting matching an old part? Send the OE number, a photo, or the thread measurement; we cross-reference it to a 24241 size within about 24 hours.

What pressure does this elbow hold? Pressure is governed by the end connection standard and the hose rating together, plus a 100% factory test on every unit.
