The KNIPEX Alligator Water Pump Pliers are built for fast, firm gripping of pipes, nuts, and fittings—without slipping. Known for their self-locking design and rugged construction, these pliers deliver high leverage and comfort in tight or awkward spaces.

What makes Alligator pliers stand out is their slim head profile, which allows better access in confined areas. They feature hardened teeth that bite into round or flat surfaces and maintain grip under heavy torque. With up to 9 adjustment positions, they adapt quickly to different sizes without requiring a button or separate tool.

Whether you’re working on plumbing, automotive repair, or HVAC systems, the Alligator pliers provide strong gripping power with minimal effort—thanks to a box-joint design that resists wobble and wear.

Compared to Other Water Pump Pliers

Compared to traditional slip-joint or channel lock pliers, Alligator pliers offer more grip stability, less hand strain, and a more compact head for better access. KNIPEX Cobra pliers offer push-button adjustment, but Alligator excels for those who prefer a simple, rugged, and fast-adjusting tool.
