Product Overview

A silicone rubber screw plug should engage its matching opening without a tilted start or excessive twisting of the flexible body. The engagement profile and final seating surface must correspond with the intended mating component.

ETOL can customize dimensions, material, hardness and color. Compare the available engagement depth and clearance around the handling region before selecting the shape. Keep the closure accessible after surrounding parts are installed so removal does not require gripping a thin edge with a sharp tool.

Clean the interface and begin insertion squarely. If movement becomes unexpectedly difficult, inspect for contamination or a profile mismatch rather than forcing the plug farther. Evaluate the assembled closure for its specified medium and service conditions. During removal, follow the intended release direction and inspect the engaged surface for tearing or permanent distortion. Correct any damage to the mating opening before fitting a replacement. A soft closure should not be relied on to absorb an incompatible engagement merely because it can deform enough to enter the hole.

Material options
Custom silicone compound; formulation and geometry developed together.
Hardness selection
Silicone options: 20–80 Shore A. A soft closure should not be relied on to absorb an incompatible engagement merely because it can deform enough to enter the hole.
Custom geometry
Compare the available engagement depth and clearance around the handling region before selecting the shape.
Fit evaluation
Evaluate the assembled closure for its specified medium and service conditions.
Color & OEM
Custom colors; OEM identification positioned outside closure contact surfaces.

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.
