Product Overview
A rectangular plug closes a shaped opening with a custom molded rubber profile. The length, width, corner radii, and seating depth should follow the receiving feature. A square cover version uses its own corresponding geometry; similar area does not make the two outlines interchangeable.
Check the corners as carefully as the straight sides. A part that fits the overall dimensions can still fold or lift where the opening radius differs from the molded profile. The receiving depth also needs to allow the body to seat without bottoming out prematurely.
Fit the plug into a clean, smooth opening and inspect the complete perimeter. Select the silicone compound for the actual medium, temperature, and cleaning conditions. Any required water seal must be evaluated on the complete assembly under its intended exposure. Keep the accessible portion clear for the planned removal method. During reuse, check the corners and retaining edges for damage, replacing the part with the matching outline rather than forcing a similar rectangular closure into an incompatible seat.
- Material options
- Custom silicone compound; formulation and geometry developed together.
- Hardness selection
- Silicone options: 20–80 Shore A. Keep the accessible portion clear for the planned removal method.
- Custom geometry
- The length, width, corner radii, and seating depth should follow the receiving feature.
- Fit evaluation
- Check the corners as carefully as the straight sides.
- Color & OEM
- Custom colors; OEM identification positioned outside closure contact surfaces.
Photos illustrate structure or material appearance only. The length, width, corner radii, and seating depth should follow the receiving feature. ETOL directly manufactures custom-shaped silicone and rubber parts to your requirements.

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.
