Klein Tools D502-12 Tongue and Groove Pliers 12 in

Product Description

The KLEIN TOOLS D502-12 is a 12-inch tongue and groove plier designed for gripping, tightening, and fastening across a wide range of jaw-opening sizes. The groove-locking mechanism holds the jaw position securely under heavy pressure, reducing slip during torquing tasks. The yellow handle provides visual identification and a comfortable grip during extended use. These pliers are non-insulated and are not rated for high-voltage or electrical work. Plumbers, pipefitters, HVAC technicians, and general trade professionals reach for this tool when working on fittings, nuts, and couplings that require adjustable jaw capacity.

The D502-12 is suited for residential and light commercial trade applications where an adjustable gripping tool is needed for pipe fittings, plumbing connections, conduit locknuts, and similar fastening tasks. The 12-inch overall length gives added leverage compared to shorter tongue and groove designs, making it practical for working in confined mechanical rooms or at overhead installations. This plier size is a standard carry item on service vans for HVAC, plumbing, and general mechanical trades.

Installation Notes

These pliers are intended for use by plumbers, HVAC technicians, pipefitters, and general mechanical tradespeople. Because the D502-12 is non-insulated, it must not be used on or near energized electrical conductors. Always confirm power or service is shut off before working in panels or near live circuits. Keep jaw contact surfaces clean to maintain secure grip on fittings.
