Eight elastomers against twelve industrial fluids. Ratings follow the public elastomer-compatibility consensus compiled from the Parker O-Ring Handbook (ORD 5700) and the RMA Rubber Handbook — IP-3 Rubber Product Selector.
Pick a fluid or a material above. Recommended and unsuitable pairings are highlighted below.
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.
