250-400mm Chrome Vanadium Groove Joint Water Pump Pliers

When the job calls for serious grip on large pipes and fittings, this 400 mm (15.7 in) Teng Tools plier delivers the leverage and jaw capacity that shorter tools cannot match. Built from chrome vanadium, the jaws resist deformation under heavy torque so you can trust them on corroded unions, oversized couplings, and stubborn nuts.

The adjustable jaw shifts between multiple groove positions, letting you match the opening to each fastener without swapping tools. A proven mechanism holds the selected position firmly, keeping the jaw stable while you apply force. At 1135 g, the tool is substantial enough to absorb reaction loads yet balanced for extended use overhead or in tight quarters.

Professional plumbers, HVAC technicians, and facility maintenance crews count on plumbing tools that work the first time and last through years of daily service. This plier fits that role whether you are assembling new supply lines, breaking loose aged drain fittings, or gripping conduit connectors on a commercial build-out. The long handle multiplies your hand force, reducing strain on repetitive tasks and letting you reach deeper into wall cavities and mechanical chases.

Add this to your toolbox alongside your existing mid-size pliers and you gain immediate capability on the large-diameter work that would otherwise require a pipe wrench or oversized adjustable. One tool, multiple jaw positions, built to professional standards.
