Siphon and plumbing connections present a recurring challenge in workshop and trade environments: standard pliers lack the jaw geometry and adjustment range to grip round union nuts and plastic fittings without causing damage. The KNIPEX 81 01 250 SB Siphon and Connector Pliers are engineered specifically for this task, with serrated gripping jaws and a 25-way adjustable box joint that allows fine, precise adjustment to accommodate diverse diameters throughout the working range. With a working capacity of 25 mm to 80 mm diameter, these pliers handle siphons, oil filters, plastic pipes, connectors, and couplings with screw connections — including Cannon circular connectors. They are also suited to the gentle loosening of hoses on nozzles and filter cartridges, where controlled grip prevents deformation of plastic fittings. The box joint provides a robust, heavy-duty platform for both tightening and loosening siphon screw connections, plastic pipe fittings, and round union nuts. Ergonomic handle geometry supports extended use, while the jaw design delivers optimum adhesion on dirt-, oil- and fat-free surfaces. The 25 adjustment positions across the 250 mm tool length ensure the pliers can be set precisely rather than approximately, reducing the risk of slippage during operation. Supplied on a self-service card and blister pack as a single pair, the KNIPEX 81 01 250 SB is a purpose-built precision plier for plumbing, automotive, and industrial connector work.
