Nitrile Rubber, Black, 90 Duro Premium Sheet is a hard-grade NBR (nitrile butadiene rubber) engineered for demanding industrial sealing, gasketing, and protective lining applications. Formulated from 100% nitrile polymer, this premium rubber sheet delivers exceptional resistance to petroleum-based oils, fuels, grease, and mechanical wear.
With a high durometer hardness rating of 90 Shore A (IRHD), it provides firm compression resistance under heavy clamping loads, preventing seal extrusion and deformation in high-pressure environments.
