One-Piece 45 Degree ORFS Female Elbow Hydraulic Hose Fitting: 24241-RW Series

Why This 45 Degree One-Piece ORFS Female Fitting Passes the Compliance Gate

The 24241-RW series is a 45 degree one-piece ORFS female fitting machined as a single integral body, so there is no brazed or welded elbow joint to fatigue or leak. The flat face and captured O-ring seal metal to metal on the port face, holding pressure and vibration without thread sealant. OEM engineers, distributors, and repair shops choose the one-piece design for high-vibration mobile and industrial circuits where a jointed elbow would be a weak point. Every unit is traceable by heat number and pressure tested before it ships.

Core Advantages

• One-piece integral body: no braze or weld seam on the elbow, improving fatigue life under pulsation.
• O-ring face seal reliability: machined flat face plus elastomer O-ring seals repeatably on SAE J1453 and ISO 8434-3 ports.
• Full size range: twenty-six catalog numbers span 9/16″X18 to 2″X12 threads and -04 to -24 hose dashes.
• Spiral-ready code: order the same geometry under 24242-XX-XXRW for spiral (interlock) hose assemblies.
• Traceable quality: batch numbering, material certificates on request, and third-party inspection per order.

Technical Specifications

What Is a One-Piece ORFS Female Hydraulic Hose Fitting?

ORFS means O-Ring Face Seal, the flat-face connection standardized as SAE J1453 and ISO 8434-3. A flat metal face presses against the flat port face and compresses an O-ring set in the face groove; there is no 37 degree cone and no thread sealant. The swivel nut turns freely on the body, letting the installer index the elbow before final torque. A 45 degree one-piece ORFS female fitting such as the 24241-RW turns the flow path diagonally in one solid body, which removes the extra joint that a two-piece elbow would otherwise add.

The suffix RW denotes the one-piece ORFS hydraulic hose fitting construction, where the bent body and the hex are formed from a single piece of steel. Threads run about one sixteenth larger than the equivalent JIC 37 degree flare, so an ORFS nut will not seat on a JIC port. This family is not interchangeable with ORB (SAE J1926), JIC 37 degree (SAE J514), or SAE 45 degree (SAE J513); always confirm the flat face and O-ring groove.

Dimensional Data

Dimensions for this 45 degree one-piece ORFS female fitting follow the drawing for the 24241-RW and 24241-TRW variants. Where a symbol carries no printed note, treat the value as dimensioned on the drawing.

The 24241-RW drawing lists A, H, C, E, S1, and S2; the tabulated dimensions are A, H, C, and S2, read directly from the specification drawing.

Full Dimension Table (Part Number Matrix)

All part numbers below for this 45 degree one-piece ORFS female fitting are for braided hose. Read each code as series-thread dash-hose dash plus the RW construction suffix: 24241-08-08RW is the 13/16″X16 one-piece 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-XXRW. Part-number suffixes TRW and RW appear as printed on the drawing for the one-piece variants.

Matériaux et traitements thermiques

Working Pressure and Operating Envelope

Rated pressure comes from the end connection standard and the hose rating together, not from the fitting alone; use the lower value. Because this one-piece ORFS hydraulic hose fitting is machined as a single body, there is no braze seam to derate the elbow, but the hose and seal still set the limit. The 45 degree one-piece ORFS female fitting is 100% factory pressure tested, and a torque and crimp data sheet for the exact part number ships with each order. Typical service temperature is -40 degree C to +120 degree C; derate for extremes per the hose and seal selected.

Selection and Ordering

How to Read the Part Number Matrix

Choose the ORFS thread E first, then the hose dash that matches your bore, and keep the RW suffix to specify the one-piece ORFS hydraulic hose fitting body. The trailing dash is the hose dash: 24241-10-12RW couples a 1″X14 ORFS female end to a -12 hose in one-piece form. Do not interpolate between listed thread and dash combinations without engineering review. For spiral hose, order the same size under the 24242-XX-XXRW code.

Thread Size and Dash Chart

Cross Reference Service

Send a photo of the old fitting, the OE part number, or the thread measurement, and we will map it to the closest 24241-RW size. Our team translates legacy and OEM part numbers into the standard HENGHUA code and notes when a one-piece body is not available in the required angle. Cross-reference turnaround is typically within 24 hours.

Emballage et logistique

The 45 degree one-piece ORFS female 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.

Assembly and Use Guide

Four-Step Crimping Procedure

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 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 supplied data sheet value. Because the one-piece nut turns freely, index the 45 degree body to your routing, then hold it while torquing. Do not wrap the threads with PTFE tape or apply sealant.

Installation Warnings

• ❌ 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 Customization and Quality Traceability

Customization Options

We laser-mark private labels, cut custom thread sizes, and specify surface finishes such as trivalent zinc, zinc-nickel, or Dacromet to match your corrosion requirement. Mixed thread and hose dash combinations can be produced to drawing in the one-piece RW construction. OEM packaging and printed box labels are available for volume programs.

Quality and Traceability System

Each batch carries a lot number that follows the parts from raw material through machining, heat treatment, plating, and final test. A 100% pressure test and thread gauge check precede packing, and material test reports ship with the order. Third-party inspection by BV or SGS can be scheduled, and quotes are typically returned within 24 hours.

FAQ

What does the RW suffix mean? RW denotes a one-piece ORFS hydraulic hose fitting: the bent 45 degree body and the hex are formed from a single piece of steel instead of being joined, so there is no braze or weld seam.

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.

Is a 45 degree one-piece ORFS female fitting available for spiral hose? Yes; for spiral (interlock) hose the code changes to 24242-XX-XXRW while the sealing face, thread, and one-piece body stay the same.

How do I order a one-piece ORFS female elbow matching an old part? Send the OE number, a photo, or the thread measurement; we cross-reference it to a 24241-RW 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.
