Cobra 87 01 250 10-Inch Water Pump Pliers
Last verified by the Lifetime Picks Editorial Team
Why we picked it
Made in Germany from forged chrome-vanadium steel
If r/Tools has a consensus pick for water pump pliers, it is the Knipex Cobra. Made in Germany from chrome vanadium steel, the Cobra adjusts with a single push of a button directly on the workpiece, snapping into 25 or more locking positions so the handles stay at a comfortable angle no matter the size of the nut or fitting. Self locking teeth bite without slipping and will not damage threads, and the box joint construction is famously tough. Plumbers, mechanics, and home tinkerers describe these as a tool you buy once and hand down. They cost more than a hardware store pair, but the precision, grip, and German build quality are exactly why the trades swear by them.
