Product Overview
A rectangular rubber seal gasket follows a straight-sided sealing path with a defined length and width. The custom natural rubber configuration should match the mating outline, corner radii, and closing gap. The long sides need to remain supported and correctly positioned as the joint is assembled.
Place the gasket without stretching it from corner to corner. A stretched side may pull away from its intended seat, while excess length can form a wave that becomes trapped during closure. Check the inner opening and any locating features against the actual mating component. Square and rectangular outlines require their own dimensions rather than a scaled visual approximation.
Material selection should reflect the medium and local environment. Natural rubber should not be assumed interchangeable with other compounds solely because the shape matches. Clean the contact faces before fitting and inspect the perimeter as the joint reaches its intended position. During service, look for repeated damage along a long side or corner that may indicate uneven support or alignment in the surrounding assembly.
- Material options
- Natural rubber. Custom formulation and color for the intended contact conditions.
- Hardness selection
- Rubber: 30–90 Shore A. A stretched side may pull away from its intended seat, while excess length can form a wave that becomes trapped during closure.

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.
