FS2501 ORFS to Pipe 90° Elbow | Hydraulic Elbow Adapter Fittings
Collection Description
The FS2501 ORFS to Pipe 90° Elbow collection comprises industrial-grade hydraulic adapters that convert a SAE O-Ring Face Seal (ORFS) male connection to a male pipe thread (commonly NPT/NPTF) at a 90-degree angle.
These forged steel elbows provide dependable, leak-resistant performance in fluid power systems requiring a directional change between a flat-face ORFS sealing surface and a tapered pipe connection.
Pressure Ratings
- Engineered for high-pressure hydraulic environments
- ORFS flat-face O-ring sealing provides robust leak resistance under pressure cycling and vibration
- NPT/NPTF pipe threads require proper thread sealant for full pressure performance
- Working pressures vary according to fitting size and system assembly
Design & Material Overview
- Material: Forged carbon steel for structural strength and reliability
- Shape: 90-degree elbow configuration for directional fluid routing
- Thread 1: Male ORFS — flat-face O-ring seal per SAE J1453 / ISO 8434-3
- Thread 2: Male pipe thread — typically NPT or NPTF per ASME B1.20.1
- Precision machined sealing surfaces for consistent engagement
- Protective finish for corrosion resistance in industrial environments
