The Clamp-All coupling was designed to fulfill a need in the plumbing industry for a heavy duty coupling to join storm and sanitary DWV piping systems above and below grade. Since the company was formed, Clamp-All not only has met the need to design and produce a high reliability coupling for hubless cast iron pipe, but has been an advocate for the development and adoption of realistic performance standards and independent third party testing.

We believe that pipe couplings should be as durable as the pipe they join. Ours is. We have built a solid tradition, through independent testing, to demonstrate the performance of our products. We have also demonstrated our commitment to quality and reliability by offering you the strongest written guarantee in the industry.

Clamp-All Corp. guarantees its hubless couplings, Approved to Factory Mutual Standard FM-1680 Class 1 at 15 PSI rated working pressure, to be free from defects in material and workmanship. Clamp-All further warrants that these couplings will not fail due to rust, rot or corrosion for the normal life expectancy of the materials joined, when installed in a normal building environment or in naturally occurring soils.

Installation must be in accordance with our printed installation instructions and in conformance with local code requirements.

Clamp-All Corp. must be notified of a suspected problem at the earliest point of detection, and prior to any removal or dismantling of the surrounding structure.

Clamp-All Corp. will, subject to the above conditions:

1. Make a full replacement for the number of couplings acknowledged by mutually agreeable independent third party analysis to have failed;
2. Clamp-All Corp. will pay for any direct material damage, excluding labor, deemed by mutually agreeable independent third party analysis, to have been caused by coupling failure;
3. Clamp-All Corp. shall not be responsible for any direct or consequential damages beyond the provisions of (1 ) and (2) above.
