Product Overview

A silicone washer gasket for food-related equipment should be selected for the actual contents, cleaning method, and temperature cycle. Custom dimensions and material formulation allow it to follow the intended joint. The finished use determines the required food-contact suitability and operating conditions.

Define the supported contact width and closing gap before choosing the section. The washer should stay within its seat rather than extend into an unsupported area where residue can collect or the edge can be displaced. Include any change in temperature during cleaning as well as normal operation.

Install the washer cleanly and check that it lies flat before the mating component closes. Use the assembly's intended fastening or closure method to control compression. During care, clean the recessed seat as well as the exposed gasket surfaces. Inspect for tears or persistent distortion and replace with the required compatible formulation and profile. A similar-looking silicone ring should not be substituted solely because it fits around the opening, especially when it was selected for a different contact environment.

Material options: Silicone. Custom formulation and color for the intended contact conditions.
Hardness selection: Silicone: 20–80 Shore A. Define the supported contact width and closing gap before choosing the section.
Custom dimensions: A similar-looking silicone ring should not be substituted solely because it fits around the opening, especially when it was selected for a different contact environment.
Fit & assembly: Use the assembly's intended fastening or closure method to control compression.
Use & inspection: Inspect for tears or persistent distortion and replace with the required compatible formulation and profile.

Photos illustrate structure or material only. A washer edge should stay supported without extending into a recess beside the sealing face. ETOL directly manufactures custom-shaped silicone and rubber parts to your requirements.

Ordering this custom component

Can the shape be adjusted to my mating parts?

Yes. Show the receiving opening, contact surfaces and clearance limits. We can review the dimensions and retaining features around the intended fit.

Which details should be agreed before tooling?

Agree the critical dimensions, material, hardness, visible surfaces and sample requirements. Explain how the part is installed and which interfaces control its function.

Can a sample help define the replacement?

A sample can help explain the structure. Compare it with the assembly because wear, swelling or compression may have changed its original dimensions.

How is the quotation for this part determined?

The material, part geometry, tooling, quantity and finishing affect the quotation. Include the intended batch size and delivery destination when describing your requirements.
