Knipex 87 51 250 Cobra Adjustable Gripping Pliers

Product Description

The KNIPEX 87 51 250 is a Cobra adjustable gripping plier designed for professional tradespeople who need secure, repeatable grip across a wide range of fastener and fitting sizes. Built from chrome vanadium steel, this tool features an extra-slim long nose V-jaw profile with a self-gripping jaw design that locks onto the workpiece under load. The box joint provides smooth, precise adjustment across 19 positions, accommodating capacities up to 1-1/4 inches (32 mm). Weighing 0.72 pounds, it balances well in hand during extended use. The plastic handle provides insulation from surface contact and a firm grip during torquing operations.

This plier is suited for HVAC, plumbing, and general mechanical work where technicians need to grip round, hex, or irregular-profile fittings without slippage. The extra-slim long nose jaw profile allows access in tight spaces around valve bodies, supply line connections, and compression fittings. The quick-adjust box joint lets technicians change jaw width in a single hand motion, reducing setup time in confined installation areas. Residential and light commercial service professionals will find this tool particularly useful for copper and PEX fitting work, sensor well removal, and similar close-quarter tasks.

Installation Notes

This tool is used by licensed plumbers, HVAC technicians, and electricians as a hand tool for gripping and turning fittings, fasteners, and valve components. Always shut off water supply or system pressure before loosening or tightening fittings. Do not use this tool on live electrical connections. Jaw serrations can mar soft finishes on brass or chrome fittings; use jaw caps or wrapping where finish protection is required.
