PEHEL/ 45 ORFS MALE/SAE O-RING BOSS
PEHEL Hydraulic Model: 1FO4-OG
QTY:
45 ORFS MALE/SAE O-RING BOSS ADAPTER
Material: Carbon steel
Brand: Pehel, OEM
Color: Silver
Connector Type: THREAD
Thread Type 1: MALE ORFS
Thread Type 2: MALE SAE O-RING BOSS
About the item:
1. This 45-degree elbow adapter complies with SAE J1453 (ORFS) and SAE J1926 (SAE O-Ring Boss/ORB) standards, acting as a transition connector to link ORFS flat face seal hose assemblies with standard ORB threaded valve ports, solving pipeline angle layout limitations in compact hydraulic systems.
2. Dual reliable O-ring sealing design: The ORFS male end adopts flat-face O-ring compression sealing, while the SAE ORB male end features under-thread O-ring boss sealing. Both structures deliver zero-leak performance under high pressure, frequent vibration and hydraulic pulsation loads.
3. Complete full-size specification range covering thread sizes from 9/16" up to 2", supporting cross-size transition combinations between ORFS and ORB ends. Each model matches dedicated standard O-rings with precisely controlled groove dimensions for stable sealing after repeated disassembly.
4. Manufactured from high-strength carbon steel with precision CNC machining, finished with uniform zinc plating anti-corrosion treatment. Integrated hexagonal wrench flats on both ends enable easy torque control during installation without scratching critical sealing faces.
5. Widely applicable to North American standard hydraulic equipment including construction machinery, injection molding machines, agricultural vehicles and industrial hydraulic power units. Its 45° angled design optimizes hose routing to reduce bending stress and extend hose service life.
