Water Pump Pliers 250 mm 2" KNIPEX Alligator®

Tongue-and-groove pliers are a type of slip-joint pliers. They are also known as water pump pliers, adjustable pliers, slippy pliers, groove-joint pliers, arc-joint pliers, Multi-Grips, tap or pipe spanners, gland pliers and Channellocks (i.e., Channellock brand pliers).

They have serrated jaws generally set 45 to 60 degrees from the handles. The lower jaw can be moved to a number of positions by sliding along a tracking section under the upper jaw. An advantage of this design is that the pliers can adjust to a number of sizes without the distance in the handle growing wider. These pliers often have long handles—commonly 9.5 to 12 inches long—for increased leverage. The weight of the tool can also vary, depending on the material used.

Description:

• More output and comfort compared to conventional water pump pliers of the same length: 9-notch adjustment positioning for 30 % more gripping capacity
• Good access to the workpiece due to slim size of head and joint area
• Self-locking on pipes and nuts: no slipping on the workpiece and low handforce required
• Gripping surfaces with special hardened teeth, teeth hardness approx. 61 HRC: high wear resistance and stable gripping
• Box-joint design for high stability due to double guide
• Robust construction, insensitive to dirt; particularly suitable for outdoor work
• Guard prevents operators’ fingers being pinched
• Chrome vanadium electric steel, forged, multi stage oil-hardened
• Self-locking on pipes and nuts: no slipping on the workpiece; the complete actuating force can be used to turn the workpieces; not having to squeeze the pliers handles reduces the required effort
