Rubber washer filter thick silicone sealing washer

A thick silicone sealing washer provides a compliant ring within a matching assembly. If that assembly also includes a filter, the sealing section and filtering element have different functions. The washer alone does not establish a mesh size, filtration efficiency or compatibility with a particular fluid system.

Check the bore, outside diameter and installed thickness against the receiving faces. The rubber should seal or cushion its intended area without obstructing the required passage. Any associated filter must remain positioned through the arrangement designed to support it, rather than be held accidentally by excessive washer compression.

Select the silicone formulation for the actual medium and cleaning conditions, then evaluate the complete joint for its duty. During maintenance, inspect the washer independently of the filter for cuts, swelling and uneven flattening. Replace using the intended geometry so changing the seal does not alter the position or clearance of the adjacent filtering component within the assembly.

Material options

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

Hardness selection

Silicone: 20–80 Shore A. Any associated filter must remain positioned through the arrangement designed to support it, rather than be held accidentally by excessive washer compression.

Custom dimensions

Check the bore, outside diameter and installed thickness against the receiving faces.

Fit & assembly

If that assembly also includes a filter, the sealing section and filtering element have different functions.

Use & inspection

During maintenance, inspect the washer independently of the filter for cuts, swelling and uneven flattening.
