Product Overview

An Oil Resistant Rubber Gasket needs a compound suited to the specific oil and operating conditions of the joint. HNBR and other available rubber families should be assessed individually, including temperature, contact duration and cleaning substances encountered during service.

The gasket may be cut or molded to the required profile. Match its outline and cross-section to the mating surfaces so material compatibility is accompanied by a sound mechanical fit. A suitable compound cannot compensate for a seat that cuts the edge or leaves part of the gasket unsupported.

Clean the joint, locate the gasket without stretching it and follow the defined assembly condition. Evaluate the completed connection under the required exposure. During service, inspect for swelling, hardening or changes in thickness as well as localized mechanical damage. Compare any uneven marks with the mating faces to identify the cause. Select the replacement around that assessment rather than using the same appearance as the only guide, and remove all old fragments before the joint is assembled again.

Material options: HNBR. Custom formulation and color for the intended contact conditions.
Hardness selection: Rubber: 30–90 Shore A. Choose HNBR firmness for the joint deformation required under its specific oil exposure; oil compatibility and compression behavior both need assessment.
Custom dimensions: Match its outline and cross-section to the mating surfaces so material compatibility is accompanied by a sound mechanical fit.
Fit & assembly: A suitable compound cannot compensate for a seat that cuts the edge or leaves part of the gasket unsupported.
Use & inspection: During service, inspect for swelling, hardening or changes in thickness as well as localized mechanical damage.

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.
