20 BSPP BONDED SEAL 90 DUROMETER NBR

Description & Features

Designed for use with male BSPP threaded connections, this bonded seal provides a reliable face seal against the end face of the male thread port, conforming to ISO 1179 specifications. The seal suits Size 20 MBSPP threads and features an NBR (nitrile rubber) O-ring bonded to a straight steel washer, combining the compression seal of an elastomer with the structural rigidity of a metal carrier.

The 20 BSPP Bonded Seal 90 Durometer NBR is rated at 90 Shore A durometer, indicating a firm compound suited to withstand hydraulic fluid exposure and maintain sealing integrity under pressure. With an inner diameter of 38.96 mm and an outer diameter of 52.38 mm, it is sized for standard Size 20 BSPP port connections. NBR construction provides good resistance to petroleum-based hydraulic fluids, making it a practical choice for hydraulic manifolds, adapters, and valve bodies using BSPP ported connections.
