08FP-18MM ORR STRAIGHT. ORING/RET RING

Description & Features

Manufactured by Brennan Industries, this straight O-ring face seal fitting with retaining ring is sized for an 8 Femaleipe thread connection paired with an 18mm metric port. The 08FP-18MM ORR Straight O-Ring/Retaining Ring fitting is designed for use in hydraulic systems where a leak-free face seal connection is required between inch and metric port sizes. The integrated retaining ring holds the O-ring in place during assembly, reducing the risk of misalignment or displacement before the connection is fully seated.

This fitting suits applications where a straight, non-adjustable connection is needed at a metric boss port. The O-ring face seal design minimizes the potential for leakage under dynamic or high-pressure conditions, making it a reliable choice for mobile and industrial hydraulic assemblies.
