KNIPEX Cobra ES Water Pump Pliers, Extra-Slim, 180 mm

Plumbers and pipefitters working in tight spaces often struggle with standard water pump pliers that are too bulky to reach recessed fittings. The KNIPEX Cobra ES 180 mm solves this with an extra-slim head and elongated jaws, allowing a secure grip on pipes and nuts even in confined installations. The self-locking mechanism holds the workpiece firmly without slipping, while the push-button adjustment provides fast, precise sizing.
