Package Information

Product Packaging

Q: What dimensions do you need to quote, and what about tolerance?

A: Please provide the pipe outside diameter (OD), clamp type, width and quantity. For custom or special applications, a drawing, photo or sample can help us confirm the dimensions and tolerances.

Q: Can the clamps be customised?

A: Yes. We support custom clamps based on your size, material, application and other requirements, including branding and packaging. You can send us a drawing, photo or sample, and we’ll help confirm the details.

Q: How long do the clamps last, and can they be reused?

A: Service life depends on the material, application, environment and installation. Clamps may be reused if they are still in good condition and the band, bolts, threads and other key parts are not damaged or deformed. For safety-critical or heavily used applications, replacing the clamp is recommended.

Q: Why does the joint still leak after installation?

A clamp alone does not seal a joint — fit, pipe-end condition and joint type also matter. Make sure the clamp is seated evenly around the joint and avoid over-tightening, which can deform the clamp or pipe and affect sealing. If the joint still leaks, check the pipe fit and condition before tightening further.

Q: How should an exhaust clamp be installed?

A: Make sure the clamp is correctly positioned and fully seated around the joint before tightening. Tighten the fastener evenly and avoid over-tightening. After installation, check that the joint is secure and properly aligned.
