Product Overview

A transparent waterproof rubber gasket should be selected as part of the complete joint it is intended to protect. The clear component can make positioning easier to inspect where its edge remains visible. Custom dimensions and material choices allow the shape to follow the assembly's contact path.

The mating surfaces need to support the gasket continuously. Check corners, openings, and changes in section for areas where the rubber could lift or become pinched. Thickness should relate to the designed closing gap so that the parts reach their intended assembled position.

Fit the gasket cleanly and examine the perimeter before applying the final closing force. Transparency can help reveal a folded edge or trapped particle, but the completed assembly still needs assessment under its intended water exposure. Include nearby joints and openings in that assessment. During servicing, clean the seat and inspect the gasket for tears or lasting distortion. Replace it with the matching profile if it no longer lies naturally in position, rather than stretching it back into a damaged seat.

Material options
Silicone. Custom formulation and color for the intended contact conditions.
Hardness selection
Silicone: 20–80 Shore A. Thickness should relate to the designed closing gap so that the parts reach their intended assembled position.
Custom dimensions
Check corners, openings, and changes in section for areas where the rubber could lift or become pinched.
Fit & assembly
Transparency can help reveal a folded edge or trapped particle, but the completed assembly still needs assessment under its intended water exposure.
Use & inspection
During servicing, clean the seat and inspect the gasket for tears or lasting distortion.

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.
