Medium-Pressure Pipe Repair Clamps
Use these clamps to repair pinholes and cracks in medium-pressure applications. They slip over your pipe, so there's no need to disassemble your system. Choose a clamp that’s long enough to cover your damaged area with at least 1” on both sides.
Clamps with partial-coverage gaskets, also known as patch clamps, repair pinholes and small cracks. The gasket on these clamps wraps around as much as 40% of the pipe. Unlike clamps with full-coverage gaskets, you'll need to line up the gasket so it completely covers the damaged area on both sides.
Fluoroelastomer gaskets resist most chemicals. They can be used with steam and other high-temperature applications.
Iron clamps are often called emergency clamps.
