The KNIPEX Cobra Pliers Set is a three-piece water pump pliers set for gripping and turning pipes and nuts, with 7-, 10-, and 12-inch (17.78, 25.4, and 30.48 cm) pliers.

• Pipe capacity from 1-1/4 in (31.75 mm) to 2 in (50.8 mm) — covers the stated pipe-size range across the set.
• Adjustment directly on the workpiece — positions the jaw opening where you need it.
• Self-locking grip on pipes and nuts — holds the work without slipping once adjusted.
• Jaws grip round, square, and hex-shaped material — suits several common workpiece profiles.
• Double-guide box joint — supports stability as the pliers grip.
• Plastic storage tray, coated handles, finger guard, and hardened teeth — keeps the set together and adds practical handling details.

When a job calls for a plier opening matched to a pipe or nut, repeated test adjustments can slow the work. This set is made for direct adjustment at the workpiece, with three plier sizes for tasks within the stated pipe-capacity range. Its jaws also accommodate more than one material shape, making the set useful across different gripping needs.

How do the KNIPEX Cobra pliers adjust?

Position the upper jaw on the workpiece, press the push button, and move the lower jaw into place. This direct adjustment avoids time-consuming trial adjustments to find the opening size. After setting, the pliers lock onto pipes and nuts without slipping.
