high temperature silicone washer round rubber washer

A silicone washer provides a round rubber layer within a custom assembly. Its inside diameter, outside diameter, and thickness should follow the receiving faces and available compression space. For a high-temperature application, the compound must suit the actual conditions at the washer rather than a general equipment temperature.

Consider the duration of exposure and any changes during cleaning, operation, or cooling. The adjoining parts may transfer heat directly into the rubber, so the local contact conditions matter. The selected silicone compound also needs to suit the medium present at the joint.

Install the washer flat on clean surfaces and keep it centered while the assembly closes. Avoid forcing an unsuitable section into the available gap through extra tightening. The complete joint determines the required sealing or spacing performance under its operating conditions. During maintenance, inspect for cuts, permanent flattening, and damage to the mating faces. A replacement should restore the original profile and selected compound so the intended contact remains consistent throughout the use cycle.
