Expanding inside pipe repair clamps

Internal Pipe Seal - Repair - Expansion Seals

WA-Internal repair clamps mount inside the pipe to repair pipe leaks. Pipe joint leaks are repaired from inside the pipe.

The units are a very low profile system that do not affect optimum water flow through the pipe.

WA internal expansion pipe seals may be used for water distribution pipes, storm water and sewer pipe repair.


The expanding clamps are full width passivated 316L stainless steal pressure plates and EDPM seals.The seal is completely compressed against the leak section.

Special tools are not required. The clamp can be used on pipes of various materials.

WA-units repair pipe sizes from 20 inch and larger.

The EDPM rubber gasket's special profile ensure a complete seal across the surface.



The expansion clamps provide a distribution of forces on the entire rubber seal, creating watertight sealing.
