Working Condition Guide
A quick decision aid for buyers and engineers who need to shortlist materials based on actual service conditions.
Recommended: FKM, ACM, selected VMQ
FKM and ACM are common choices for hot oils and lubricants; silicone is used more for wide-temperature static service than for hydrocarbon-rich media.
Recommended: NBR, HNBR, ACM
NBR is the standard choice for many oil seals, HNBR adds durability, and ACM is often used where hot lubricants are a main concern.
Recommended: PTFE
Well suited for aggressive media, clean process systems, and sealing applications that prioritize chemical resistance and low friction.
Recommended: PU
Best matched with hydraulic and dynamic sealing systems that require strong wear resistance.
Recommended: EPDM
Well suited for outdoor exposure, water-related systems, and ozone-resistant applications.
Recommended: NBR
A cost-effective default option for broad sealing applications in manufacturing and maintenance.
