WASHER

Description & Features

Designed for use with size 08 male BSPP threaded connections, this bonded seal washer conforms to ISO 1179 and provides a reliable face seal at the port interface. The bonded construction combines a straight steel carrier with a 90 durometer NBR sealing element, giving the assembly the rigidity needed to seat consistently under torque while the elastomer accommodates surface variation to prevent leakage.

With an inner diameter of 18.64 mm and an outer diameter of 28.58 mm, this Washer is sized for standard 08 MBSPP ports commonly found in hydraulic manifolds, valves, and cylinder end caps. NBR compound at 90 durometer offers good resistance to petroleum-based hydraulic fluids across a broad service temperature range. Manufactured by Brennan Industries under the 9900 Series. California residents should note that this product is subject to Prop 65 warning requirements.
