FS2408-04 ORFS Plug

FS2408-04 ORFS Plug | Steel Hydraulic O-Ring Face Seal Plug

The FS2408-04 ORFS Plug is a straight hydraulic sealing component designed to close unused 9/16-18 Male O-Ring Face Seal (ORFS) (-04) ports. Manufactured from high-strength steel, it provides a secure, leak-free seal in high-pressure hydraulic systems.

Built in compliance with SAE 520109 standards, this plug uses ORFS (O-Ring Face Seal) technology, where a precision-machined flat face and elastomer O-ring work together to prevent leakage, even under vibration and pressure spikes. It is widely used in hydraulic systems where reliability and long-term sealing performance are critical.
