Product Overview
A rubber blanking plug closes an unused opening with a solid rubber section and a profile that retains against the surrounding component. FKM or Viton selection should follow the substances and temperatures at that location. The intended blanking role also needs to be clear, since a cover used to keep debris out has different requirements from a closure exposed to pressure.
Check the hole geometry, supporting thickness, and space behind the opening. The retaining region should engage without relying on excessive stretch or an exposed edge pressed against nearby hardware. Leave the intended removal access where the opening may be needed during maintenance.
Seat the plug on a smooth, clean edge and inspect the perimeter for a folded lip. Avoid piercing the center to help installation or removal. If the opening later carries a cable or pipe, replace the blank with a suitable passage component. During service, inspect the rubber for contact damage and changes in shape, preserving the specified compound when a replacement is fitted.
- Material options
- FKM compound options, customized alongside the profile and contact conditions.
- Hardness selection
- Solid rubber options: 30–90 Shore A. Avoid piercing the center to help installation or removal.
- Custom geometry
- Check the hole geometry, supporting thickness, and space behind the opening.
- Fit evaluation
- FKM or Viton selection should follow the substances and temperatures at that location.
- Color & OEM
- Custom colors; OEM identification positioned outside closure contact surfaces.

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.
