FS4000 O-Ring Face Seal Adapters | Buna-N (NBR) Face Seal O-Rings

Product Description:

The FS4000 O-Ring Face Seal (ORFS) Adapters are designed to deliver reliable, leak-free sealing in high-pressure hydraulic systems. These adapters use Buna-N (Nitrile) face seal O-rings with a 90-durometer hardness, engineered specifically for use with SAE O-Ring Face Seal fittings. ORFS sealing technology is widely used in industrial and mobile hydraulics due to its superior resistance to vibration, pressure spikes, and fluid leakage.

Pressure Ratings
