Siphon and connector pliers present a common challenge: achieving a secure, controlled grip across a wide range of pipe and fitting diameters without damaging the workpiece. The KNIPEX 81 03 250 SB addresses this through fine adjustment that allows ideal adaptation to diverse diameters, combined with a 25-way adjustable box joint that provides precise, repeatable positioning across the full working range. Designed for tightening and loosening siphon screw connections, plastic pipe fittings, and round union nuts, these pliers are equally suited to connectors and couplings with screw connections such as Cannon circular connectors. They also allow gentle loosening of hoses on nozzles and filter cartridges, making them a versatile addition to any professional plumbing or workshop toolkit. The serrated gripping jaws deliver optimum adhesion on dirt-, oil-, and fat-free surfaces. The working capacity covers diameters from 25 mm to 80 mm, accommodating siphons, oil filters, plastic pipes, and connectors up to 80 mm diameter. The 25-way box joint adjustment ensures a consistent, robust hold at every setting, while the ergonomic handle geometry reduces operator fatigue during extended use. Supplied on a self-service card and blister for convenient retail display and storage, the set contains one KNIPEX 81 03 250 SB Siphon and Connector Pliers at 250 mm overall length. The robust, heavy-duty construction reflects the demanding professional environments these pliers are built to serve.
