The OATEY PP8401 is a universal pipe repair clamp designed to stop leaks on small-diameter pipe quickly and without cutting out the damaged section. The clamp adjusts to fit 3/8 inches through 3/4 inches IPS pipe and 1/2 inch through 1 inch copper pipe, making it one of the most versatile single-clamp solutions a plumber can carry on the truck. Each unit ships complete with nuts, bolts, and a pre-cut gasket so the technician can go straight to work. It is well suited for residential and light commercial plumbing repairs where a fast, reliable mechanical fix is needed.
This clamp is used on water supply lines, drain lines, and other low-pressure piping where a pinhole, split, or crack has developed. Its adjustable range covers the most common small-bore pipe sizes found in residential construction, including both threaded IPS and copper tubing. Plumbers and service technicians reach for this style of clamp when a permanent repair needs to happen fast and pipe replacement is not immediately practical.
Designed as an OEM-style mechanical repair clamp for residential and light commercial plumbing pipe in the 3/8 inches to 3/4 inches IPS range and 1/2 inch to 1 inch copper tubing range.
Installation should be performed by a licensed plumber or qualified service technician following local plumbing code requirements. Shut off water supply and relieve line pressure before applying the clamp. Center the gasket over the damaged area, wrap the clamp body around the pipe, and tighten the bolts evenly to compress the gasket against the pipe surface. Do not overtighten, as uneven bolt torque can cause the gasket to seat improperly and result in continued leakage.
