180 mm water pump plier for bolt and pipe work

The Knipex 88 01 180 SBA is a self-locking groove-joint plier built for gripping bolts, nuts and pipes. Chrome vanadium steel jaws are hardened to approximately 61 HRC for wear resistance. A forged closing limiter prevents finger pinching during use. Nine adjustment positions cover a maximum jaw opening of 1 1/2 in.

Nine-position groove joint sets the practical range

The box-joint design allows nine discrete jaw-width settings up to 1 1/2 in. Jaw width is 7/8 in and jaw length is 1 in, limiting the maximum nut or pipe diameter that can be gripped. Serrated V-shaped jaws provide bite on round and flat surfaces but are not insulated for electrical work. The tool is not tether-ready and has no non-sparking rating.

Replaces fixed-jaw wrenches when fastener sizes vary

This plier upgrades from single-size open-end or box wrenches by covering multiple diameters in one tool. The jump is worth it when a job requires frequent size changes on bolts, nuts or pipes up to the stated opening. It does not suit applications needing insulated handles, tether attachment or non-sparking certification.

Questions about this item

Which jaw-opening positions does the 88 01 180 SBA offer?

The plier provides nine groove-joint positions, allowing the V-shaped jaws to adjust from closed up to a maximum opening of 1 1/2 inches for bolts, nuts or pipes.

What does the 61 HRC tooth hardness mean when I am gripping a pipe?

Teeth hardened to approximately 61 HRC resist wear and bite securely into pipe or nut surfaces without rounding off, giving a firm, self-locking hold during high-torque turning.

How does the box-joint design affect the tool's performance?

The forged box joint keeps the jaws aligned under load, while the built-in closing limiter prevents finger pinching, so the 180 mm plier stays stable and safe when maximum leverage is applied.
