Proto J836HD Straight Pipe Wrench 36 in Steel

Product Description

The PROTO J836HD is a straight pipe wrench built for heavy-duty plumbing and pipefitting work. It measures 36 inches in overall length and handles pipe up to 5 inches in diameter. The wrench is constructed from steel throughout, giving it the durability needed for repeated use on iron, steel, and black pipe in demanding jobsite conditions. Its full-length design provides the extended leverage required when breaking loose large-diameter fittings or making up threaded connections on main supply lines and commercial piping systems. Plumbers, pipefitters, and mechanical contractors reach for a wrench this size when smaller tools lack the torque advantage the job demands.

The J836HD is well suited for residential and commercial plumbing installations, industrial pipefitting, HVAC hydronic piping, and general mechanical contracting. It is particularly useful on larger-diameter threaded pipe connections found in main water service lines, gas mains, steam piping, and drainage systems. The 36-inch length gives a technician the mechanical advantage needed on stubborn or heavily corroded connections that shorter wrenches cannot break free. This wrench is intended for professional use and is sized for tasks that go beyond what standard 14-inch or 18-inch wrenches can accomplish.

Installation Notes

This wrench is intended for use by licensed plumbers, pipefitters, and qualified mechanical trades. Always shut off the water supply or gas service and relieve system pressure before working on any threaded pipe connection. Inspect the jaw teeth and adjustment mechanism before each use and do not use a wrench with damaged or worn teeth on pressurized systems. Follow all applicable IPC and IFGC guidelines when making or breaking connections on gas or water supply piping.
