Product Overview
A Flat Rectangular Rubber Gasket suits a joint whose sealing path follows a rectangular outline across flat mating faces. Its thickness and perimeter should be chosen together, especially in a shallow assembly where a small change in gasket height affects how the cover or frame closes.
Custom cutting or molding can define the opening, outer boundary and any required clearance features. Compare the narrowest section of the sealing land with the gasket width rather than measuring only the longest sides. The selected compound should reflect the substances and temperatures at that joint.
Position the gasket with its long edges relaxed and its corners aligned before fastening. Avoid sliding the upper face across it, which can draw one side into the opening. Inspect the completed edge for a section protruding farther than the rest. During disassembly, note where the old gasket contacted each face; an uneven imprint can help identify a seating or alignment problem that should be corrected before fitting the replacement.
- Material options
- Rubber. Custom formulation and color for the intended contact conditions.
- Hardness selection
- Rubber: 30–90 Shore A. Set the flat rectangular section and rubber grade for the available closing space, then compare compression along the long and short sides.
- Custom dimensions
- Compare the narrowest section of the sealing land with the gasket width rather than measuring only the longest sides.
- Fit & assembly
- Position the gasket with its long edges relaxed and its corners aligned before fastening.
- Use & inspection
- During disassembly, note where the old gasket contacted each face; an uneven imprint can help identify a seating or alignment problem that should be corrected before fitting the replacement.

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.
