McMaster 4570K118 Low-Pressure Pipe Repair Clamp, Partial-Coverage Buna-N Gasket, 3" Long, 3-1/2" Pipe OD
Repair pinholes and cracks in low-pressure applications without having to disassemble your system. All clamps are 304 stainless steel for very good corrosion resistance. Choose a clamp that’s long enough to cover your damaged area with at least 1” on both sides.
Buna-N Gasket—Most Buna-N gaskets work with a variety of media, such as water, oil, and hydraulic fluid.
Partial-Coverage Gasket—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.
NSF/ANSI 61—Clamps that meet NSF/ANSI 61 are safe for use with drinking water systems.
