Factory price custom silicone FKM rubber seals o ring

Custom FKM rubber seals o ring designs should be matched to the actual medium, temperature and contact conditions of the joint. A silicone alternative requires its own material assessment rather than being treated as interchangeable because it shares the same shape.

ETOL offers custom dimensions and colors with selected elastomer constructions. Define the seat and intended assembled compression alongside the compound. Keep the inner and outer contact regions supported by their mating surfaces.

Install the ring without twisting it and use the joint's prescribed assembly method. Evaluate the completed interface under its intended duty. During maintenance, inspect for material changes and localized mechanical damage, comparing the contact pattern with the mating hardware. A swollen or altered profile may point to exposure, while a cut at one location may identify a sharp edge or fitting obstruction. Correct the cause before replacement, and remove old fragments from the seat so the next ring does not rest on debris that changes its contact.

Material options

FKM / Silicone. Custom formulation and color for the intended contact conditions.

Hardness selection

Rubber: 30–90 Shore A. Silicone: 20–80 Shore A. Define the seat and intended assembled compression alongside the compound.
