Knipex 87 21 250 Sba Tongue and Groove Pliers 2 in

Product Description

The KNIPEX 87 21 250 SBA is a quick-adjusting tongue and groove plier built for trade professionals who need reliable grip across a wide range of fastener and fitting sizes. The jaw opens to 2 inches of capacity and locks into any of 25 positions using a self-locking box joint — no slipping under load. The serrated jaw is machined from chrome vanadium steel and oil-hardened at multiple stages for long service life. Overall length sits at 9.9 inches, keeping the tool manageable in tight spaces. The plastic handle provides insulation from vibration. At 0.74 pounds, it handles daily carry without fatigue.

This plier is suited for residential and light commercial plumbing, HVAC, and mechanical work. The 25-position quick-adjust mechanism allows fast sizing changes when moving between pipe diameters, fittings, or hardware. The box joint design resists racking under torque, making it a practical choice for pipe work, conduit fittings, and general mechanical assembly. Licensed plumbers, HVAC technicians, and pipefitters are the primary users. The DIN ISO 8976 standard compliance ensures the tool meets international dimensional and performance requirements.

Installation Notes

This tool is used by licensed plumbers, HVAC technicians, and electricians for gripping, tightening, and loosening fittings and hardware. Always verify the jaw is fully locked into a position before applying torque to prevent jaw slip. Do not use this plier as a substitute for a torque wrench where precise fastener torque values are required. Follow applicable codes such as IPC or IFGC when working on piping systems.
