Factory custom molded heat resistant silicone seals rubber gasket

Silicone seals provide custom compressible interfaces between adjoining parts. The profile should follow the receiving joint, with thickness and compound selected for its working conditions. In a heated assembly, the seal needs to suit the actual temperature cycle as well as the mechanical fit.

Check the medium, exposure duration, and cleaning stages. The temperature at the seal may differ from the surrounding environment, and the selected compound should be chosen accordingly. The mating parts also need to support the rubber evenly as the joint reaches its final position.

Install the seal onto clean surfaces without stretching it around an incompatible outline. Inspect for trapped edges as fasteners are secured in the sequence required by the assembly. Any required sealing performance must be evaluated on the complete joint under its intended conditions. During maintenance, look for cuts, permanent deformation, and damage to the receiving faces. A replacement should restore the designed profile and compound rather than use additional compression to compensate for an unsuitable seat.
