Product Overview

Heat resistant silicone plugs close suitably matched openings in applications where the selected silicone formulation can accommodate the thermal conditions. The relevant temperature is the exposure at the plug itself, including heating duration and the way the surrounding part transfers heat. A generic silicone designation does not establish a universal temperature limit.

Choose the insertion profile around the opening and its required engagement depth. Heating can affect both the receiving part and the rubber fit, so evaluate the plug through the actual process cycle rather than judging only a room-temperature insertion. Any sealing or pressure requirement needs separate consideration within that arrangement.

Keep sharp burrs away from the plug's contact surface and seat it without folding an edge. Removal and handling must suit the process and the condition of the surrounding part. Inspect reusable plugs for cuts, permanent distortion and changes in fit before the next cycle. A plug that still enters the opening may no longer maintain the same contact after repeated thermal exposure.

Material options: Custom silicone compound; formulation and geometry developed together.
Hardness selection: Silicone options: 20–80 Shore A. Choose the insertion profile around the opening and its required engagement depth.
Custom geometry: A plug that still enters the opening may no longer maintain the same contact after repeated thermal exposure.
Fit evaluation: Heating can affect both the receiving part and the rubber fit, so evaluate the plug through the actual process cycle rather than judging only a room-temperature insertion.
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.
