Product Overview
Custom rubber products for heat or oil exposure should be developed around the function and conditions of each individual part. NBR, EPDM and silicone are different material families, so a group of components should not be assigned one broad resistance claim simply because they share a supplier or a similar appearance.
Define the contact medium, temperature cycle and mechanical role before choosing the formulation. Custom shapes can follow openings, support points or other interfaces, with the geometry selected for the actual mating parts. Color and suitable markings can help identify configurations within an assembly.
Evaluate each selected part in its intended position and operating sequence. A sealing component, protective cover and mount may need different profiles and material characteristics even within the same machine. During production and maintenance, keep those configurations clearly distinguished. If service exposure changes, reassess the relevant formulation rather than replacing parts only by size. Preserve the designated geometry and material together so a repeat order reproduces the component that was evaluated for that particular use.
- Material options
- EPDM / NBR / Silicone. Custom formulation and color for the intended contact conditions.
- Hardness selection
- Rubber: 30–90 Shore A. Silicone: 20–80 Shore A. Define the required deformation for the particular molded part before comparing compounds; retain the evaluated geometry when changing the formulation.
- Custom dimensions
- Custom shapes can follow openings, support points or other interfaces, with the geometry selected for the actual mating parts.
- Fit & assembly
- Color and suitable markings can help identify configurations within an assembly.
- Use & inspection
- If service exposure changes, reassess the relevant formulation rather than replacing parts only by size.

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.
