China supplier factory price EPDM rubber washer

An EPDM rubber washer should be selected for the conditions on both of its contact faces and around its exposed edge. The inside of a joint may encounter a different medium from the outer face, so those exposures belong in the same material review.

ETOL offers custom dimensions, hardness and color. Match the inner opening to the locating component and the outer diameter to the available supporting face. Define the space provided for the washer in the assembled joint rather than judging only its loose thickness.

Fit it flat on a clean seat and keep the hole centered as the mating parts come together. Follow the assembly's specified compression or fastening condition, then evaluate the intended function under actual service conditions. During disassembly, inspect both faces rather than only the accessible outside edge. An uneven impression or local cut can identify a mating problem that needs correction. Remove old fragments before replacement and avoid stacking a new washer over remnants that alter the available space and contact pattern.
