O-Ring For Bspp Thread 90 Nbr

Description & Features

Designed for use with G 1/8 - 28 Bspp threaded connections, this 1/8" sealing component from Adaptall provides a reliable face seal at the thread interface. Made from 90 durometer Nbr (nitrile butadiene rubber), it offers solid resistance to petroleum-based hydraulic fluids, making it well suited to hydraulic and fluid power assemblies where a consistent, leak-free thread seal is required.

The O-Ring For Bspp Thread 90 Nbr is a component-type fitting element, intended to seat against the face of a Bspp port rather than relying on thread deformation alone for sealing. The 90 Shore A hardness rating reflects a firmer compound appropriate for higher-pressure sealing duties typical of hydraulic circuit connections.
