Product Overview

A rubber pipe seal creates a flexible interface within a pipe connection or opening. For a heat-exposed arrangement, the selected compound should suit the temperature at that interface, the medium being handled and the duration of contact.

ETOL customizes the profile, dimensions, hardness, material and color. Compare the mating surfaces and the available assembled space before choosing the seal's cross-section. A part that fits loosely on the bench may be compressed differently once the pipe connection reaches its specified position.

Keep the contact surfaces clean and use the assembly method designated for the system. Check that the rubber has not rolled or been displaced while the joint closes. Evaluate the complete connection under its intended operating conditions. During service, follow the appropriate cooling and release procedure before opening the joint. Inspect the seal for hardening, cuts or an uneven impression and compare any marks with the mating surfaces. Correct a sharp edge or misalignment before installing a replacement so the new component is not exposed to the same concentrated contact.

Material options: Silicone. Custom formulation and color for the intended contact conditions.
Hardness selection: Silicone: 20–80 Shore A. A part that fits loosely on the bench may be compressed differently once the pipe connection reaches its specified position.
Custom dimensions: ETOL customizes the profile, dimensions, hardness, material and color.
Fit & assembly: Compare the mating surfaces and the available assembled space before choosing the seal's cross-section.
Use & inspection: Correct a sharp edge or misalignment before installing a replacement so the new component is not exposed to the same concentrated contact.

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.
