Compact high-tech water pump pliers — grip quickly, adjust finely. The Knipex 87 01 180 Cobra, at 180mm long, is one of the medium-sized models in the Cobra water pump pliers range. The benefits are plain to see: compact, light and stable, they position on the component quickly and are self-locking, on both pipes and nuts.
Due to its compact size, it's particularly suited to work in confined spaces. Despite this, it achieves a gripping capacity for pipes up to a diameter of 1½ inches (42mm) and for nuts up to a wrench opening of 36mm.
For pipes, nuts, sleeves and various other components, the professional user applies the Knipex Cobra quickly and accurately with just one hand movement. The spring-loaded hinge bolt locks securely into place without adjusting inadvertently. Thanks to 18-fold fine adjustment, the Cobra 87 01 180 can be ideally adjusted to different sizes of component, and this fine adjustment also ensures a hand-friendly gripping position at every grip width.
The Cobra is further stabilised by its box joint design — unlike pliers with mounted joints, no tilting forces arise when under strain, and the handles stabilise each other in the joint. The jaw geometry developed by Knipex clamps onto the component securely by itself, so the user can put all their energy into the desired movement — turning, tightening or releasing — without pressing the handles together and losing energy in the process.
Forged from chrome vanadium steel and hardened through a multiple-stage process, the gripping teeth are additionally induction hardened using high-frequency current to a hardness of approximately 61 HRC for a lasting, secure bite.
Achieving up to 42mm pipe capacity in a compact 180mm tool is a genuine standout — most pliers this size don't grip that wide — and the self-locking jaw geometry means grip strength comes from the component itself rather than requiring constant hand pressure, reducing fatigue over a working day. Box-joint construction avoids the tilting forces a mounted joint would suffer under strain, giving a stable, reliable hold even on tough, stuck fittings.
