The design of KNIPEX’s Siphon and Connector pliers allows for 25 adjustable positions and is heavy-duty enough to be used for tightening and loosening siphon screw connections. It can also be used to tighten and loosen plastic pipe fittings and round union nuts for connectors and couplings with a screw connection (for example Cannon circular connectors). This new product can even be used to gently loosen hoses on nozzles.
