Product Overview
A round rubber washer with grooves includes recessed features that must be interpreted as part of the working profile. A groove may correspond to a locating or contact feature in the receiving assembly; it should not be assumed to serve as a fluid channel simply because it forms a recess in the rubber.
Establish which side faces each mating component. The groove's position relative to the bore and outer edge can make orientation important even when the loose washer appears symmetrical from a distance. Compare the whole cross section with the intended seat, including the lands beside the groove that will make contact.
During fitting, ensure those lands reach their mating faces without the groove being flattened by an incompatible projection. Keep residue out of the recess so its geometry remains available for the intended function. For replacement, inspect the old groove under good visibility and distinguish trapped deposits from damaged rubber. The custom material and dimensions should match the actual joint duty. A flat washer with the same diameter cannot reproduce the recessed profile or its locating relationship.
- Material options
- Rubber. Custom formulation and color for the intended contact conditions.
- Hardness selection
- Rubber: 30–90 Shore A. Choose the rubber response with the groove correctly oriented to the bore; a recessed face can change local compression despite a symmetric outline.
- Custom dimensions
- A flat washer with the same diameter cannot reproduce the recessed profile or its locating relationship.
- Fit & assembly
- Compare the whole cross section with the intended seat, including the lands beside the groove that will make contact.
- Use & inspection
- For replacement, inspect the old groove under good visibility and distinguish trapped deposits from damaged rubber.

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.
