Product Overview
A rubber seal ring/washer for a warm installation needs its compound selected around both heat and chemical exposure. EPDM and FKM are different material options, and the appropriate choice depends on the medium, temperature cycle, and required contact conditions. The custom geometry can then be developed for the joint.
Consider the full operating cycle, including warm-up, sustained operation, cooling, and cleaning. A seal may encounter different substances during maintenance from those present during normal use. Those conditions should be combined with the required hardness and compression when selecting the formulation.
Dimension the ring from its functional seat. The inside opening, outside boundary, and section thickness determine whether the rubber is supported when the mating parts close. Install it without twisting or pinching the edge, and use the assembly's intended closing method. During maintenance, examine the contact area for lasting deformation or damage. A replacement should match the specified material as well as the visible dimensions, since an apparently identical ring may behave differently in the same environment.
- Material options
- EPDM / FKM. Custom formulation and color for the intended contact conditions.
- Hardness selection
- Rubber: 30–90 Shore A. Install it without twisting or pinching the edge, and use the assembly's intended closing method.
- Custom dimensions
- The inside opening, outside boundary, and section thickness determine whether the rubber is supported when the mating parts close.
- Fit & assembly
- A rubber seal ring/washer for a warm installation needs its compound selected around both heat and chemical exposure.
- Use & inspection
- During maintenance, examine the contact area for lasting deformation or 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.
