Gasket & Seal Material Compatibility Lookup

This tool draws on the preserved material records of Bentley Manufacturing — a precision gasket, washer and diaphragm maker since 1955 that worked in TPE, TPR, Teflon and elastomers. It is a preliminary screening reference, not a substitute for testing.

Fluid / chemical

Excellent Good Fair (limited) Not recommended

Preliminary screening only. Compatibility depends on fluid concentration, temperature, pressure and exposure time. Always confirm a specific grade with the material supplier and, for critical seals, run an immersion or coupon test before production.

References. The four-level ratings follow the public elastomer-compatibility consensus consolidated from the Parker O-Ring Handbook (ORD 5700) and the RMA Rubber Handbook — IP-3 Rubber Product Selector, cross-checked against published supplier chemical-resistance charts (DuPont, Dow, ExxonMobil). Where the literature disagrees, the more conservative rating is shown.
