Product Overview

A custom rubber plug can be developed in EPDM, FKM or another selected formulation for a particular opening. The medium, temperature and contact duration should guide the material choice. Compounds with different exposure behavior may also differ in their installed handling, so the fit should be checked using the intended formulation.

Define the receiving bore or seat, available depth and removal access before choosing the body profile. Custom dimensions, hardness and color allow the closure to follow the assembly. Any required sealing or pressure duty should be assessed with the complete retained arrangement.

Keep the mating region clean during fitting and inspect the plug for cuts or particles. Seat it at its developed position without forcing a changed or swollen body into the opening. During maintenance, look for altered insertion resistance, permanent distortion and uneven contact marks. If a material substitution is considered, review both exposure suitability and installed geometry rather than assuming that an identical outside shape provides the same closure behavior.

Material options: EPDM / FKM compound options, customized alongside the profile and contact conditions.
Hardness selection: Solid rubber options: 30–90 Shore A. Any required sealing or pressure duty should be assessed with the complete retained arrangement.
Custom geometry: Define the receiving bore or seat, available depth and removal access before choosing the body profile.
Fit evaluation: If a material substitution is considered, review both exposure suitability and installed geometry rather than assuming that an identical outside shape provides the same closure behavior.
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.
