Product Overview

Silicone rubber end caps tips cover the ends of components with a custom molded rubber profile. Size and color can be adapted to the product, allowing the cover to follow the receiving shape while remaining visually coordinated with the assembly. The internal fit should be established before choosing the visible outline.

Check the end diameter or other cross section, the available insertion length, and any lip or taper. A cap that stops too early may leave the intended area exposed, while an overly deep socket can place the closed end where it lacks support. The outer shape also needs clearance from adjoining parts.

Fit the cap onto a clean surface without rolling its edge or overstretching the rubber. Inspect the position after assembly and confirm it remains located during the intended handling. Select the compound for the actual contact conditions and cleaning products. Color can help distinguish versions, but replacements should match the dimensions and material as well as appearance. Replace damaged caps before the underlying end becomes exposed.

Material options: Custom silicone or rubber formulation, with dimensions and color adapted to the mating component.
Hardness range: Silicone: 20–80 Shore A; rubber: 30–90 Shore A. Compare firmness under load at the intended contact face. The outer shape also needs clearance from adjoining parts.
Custom profile & fit: Check the end diameter or other cross section, the available insertion length, and any lip or taper.
Assembly considerations: Inspect the position after assembly and confirm it remains located during the intended handling.
Design check: Select the compound for the actual contact conditions and cleaning products.

FIND THE RIGHT FIT

End Cap Size Catalog

Compare inside diameter A with the outside of the part being covered. Check inside depth C and overall dimensions B and D for available clearance. These RSE references show a round cap with one closed end.

RSE End Caps

43 closed-end cap sizes. A is the inside diameter and C is the usable internal depth; B and D describe the outside envelope.

Installation

Check access, mating dimensions and the fitting sequence.

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.
