Product Overview

A flat food grade rubber seal is a shaped gasket for a selected joint, with the outline and compound tailored to the application. The silicone gasket offering concerns the fitted rubber part, so its dimensions should follow the mating faces and the space available when they close. The finished material must suit the actual food contact and cleaning conditions.

Identify the sealing path and keep the internal opening aligned with the passage it surrounds. Avoid leaving unsupported rubber projecting into that passage or beyond the outer seating face. A cut or molded construction can be chosen for the required shape. Fit the gasket without stretching its corners and keep residue off the contact faces. Evaluate the completed joint under the intended use rather than relying on material naming alone. During cleaning or service, inspect for a folded edge or a narrow cut where the joint has contacted the rubber. Replace damaged material after correcting the seating issue, and keep the evaluated compound consistent when the seal is reordered or its outline revised.

Material options: Silicone. Custom formulation and color for the intended contact conditions.
Hardness selection: Silicone: 20–80 Shore A. Set firmness for the flat seal outline and intended closing gap, allowing the corners to compress while remaining located on the sealing land.
Custom dimensions: The silicone gasket offering concerns the fitted rubber part, so its dimensions should follow the mating faces and the space available when they close.
Fit & assembly: Identify the sealing path and keep the internal opening aligned with the passage it surrounds.
Use & inspection: During cleaning or service, inspect for a folded edge or a narrow cut where the joint has contacted the rubber.

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.
