Product Overview
A gasket seal ring for concrete pump parts should be selected for the exact component and joint it serves. This custom Buna-N option can be dimensioned around the mating interface. The material formulation needs to suit the substances and temperatures at that location, which may differ between parts of the machine.
Identify the seat and closing arrangement before choosing the ring. The center opening, section, and supported width determine how it fits. Pressure capability and operating conditions belong to the complete pump connection and should follow the equipment's requirements rather than being inferred from the gasket material.
Service the joint using the machine's intended procedure and conditions for access. Clean the mating faces and remove deposits without damaging the sealing path. Position the ring without twisting or stretching it into place, then close the assembly with the specified hardware arrangement. During inspection, note repeated wear or uneven deformation and check the corresponding seat. Replace the correct profile and formulation instead of adding thickness to compensate for a damaged or misaligned component.
- Material options
- Rubber. Custom formulation and color for the intended contact conditions.
- Hardness selection
- Rubber: 30–90 Shore A. Pressure capability and operating conditions belong to the complete pump connection and should follow the equipment's requirements rather than being inferred from the gasket material.
- Custom dimensions
- The center opening, section, and supported width determine how it fits.
- Fit & assembly
- Position the ring without twisting or stretching it into place, then close the assembly with the specified hardware arrangement.
- Use & inspection
- Replace the correct profile and formulation instead of adding thickness to compensate for a damaged or misaligned component.

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.
