Product Overview

Rubber flat square gaskets should have an outline and thickness matched to the joint's supported sealing area. Corners and straight edges may experience different compression if the mating components are not flat or the closing force is uneven. The custom geometry should follow the actual receiving surfaces.

Material, dimensions, hardness and color options allow the gasket to match the application. Define the internal opening and outer boundary so neither leaves an unsupported edge in the working joint. Select the compound for the medium and operating environment.

Before installation, inspect both mating faces and keep them clear of residue. Position the gasket without stretching or wrinkling it, then close the joint through the intended sequence. Evaluate sealing under representative conditions. During maintenance, compare the imprint at the corners with the marks along the sides. A locally flattened or extruded section can identify an alignment or support issue. Correct the receiving condition before simply increasing thickness, which may create additional distortion if the available space is unchanged.

Material options
Rubber. Custom formulation and color for the intended contact conditions.
Hardness selection
Rubber: 30–90 Shore A. Corners and straight edges may experience different compression if the mating components are not flat or the closing force is uneven.
Custom dimensions
Rubber flat square gaskets should have an outline and thickness matched to the joint's supported sealing area.
Fit & assembly
Position the gasket without stretching or wrinkling it, then close the joint through the intended sequence.
Use & inspection
Before installation, inspect both mating faces and keep them clear of residue.

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.
