Overview
The Knipex 87 01 250 is a 250 millimeter, about 10 inch, plier with a plastic-coated handle, part of Knipex's self-adjusting pump plier line. It is built to grip and turn rounded or irregular shapes without a manual adjustment screw.
The 87 01 series is known for a push-button self-adjusting jaw, letting the jaws grip pipe, nuts, and fittings across a range of sizes without resetting a pivot pin. That mechanism is the main reason this style of plier shows up in plumbing and general repair kits over a fixed adjustable wrench.

Who it's for
Anyone doing plumbing, automotive, or general repair work who needs a plier that grips varying round or hex shapes quickly. Not the pick for precision electronics work needing fine tip control.
Pros and cons
- Self-adjusting jaw grips varying pipe and fitting sizes
- Plastic-coated handle for grip
- Compact enough for a tool pouch
- Not built for fine precision or electronics work
- No cutting edge included
- Exact jaw opening range not listed
Performance notes
The self-adjusting jaw mechanism in this Knipex line lets the tool grip a range of diameters in one motion, closing to fit rather than requiring you to preset a pivot point. The plastic handle covering adds grip without the tool becoming bulky.
