When odour traps need to be opened on kitchen and bathroom fittings, they can be gripped and twisted powerfully in a measured way using the siphon and connector pliers from Knipex. The pliers can unscrew and tighten screw joints on plastic pipes and sensitive connectors, and are also suitable for detaching hoses that have become stuck to supports – e.g. coolant hoses. Surface contour adapted to the pipe protects screw joints The gripping jaws has been designed for large pipe diameters. As a result of their round shape, they are used with union nuts on connectors and to screw joints of pipes conveying liquids and gas. Such connectors establish an electrical connection that is weather and vibration resistant. The replaceable plastic inserts offer particularly good protection for sensitive surfaces. Versatile and tough: 25 possible settings and box joint design With the 25 possible settings, which can be conveniently set to the desired grip width using the fine adjustment push button, the Knipex syphon and connector pliers have a large gripping range of Ø 10-75 mm. Thanks to the box joint design and manufacture from oil-hardened chrome vanadium electric steel, the pliers are very tough. The high quality chrome plating provides good corrosion resistance.

These are for 2-3 inch plastic nuts like on a cistern siphon or the nuts to a trap. All that said, they aren't even very good for that. **Q: Are they effectively soft jaws** A: Yep **Q: Do these come with the new tips on not the old style like others are trying to sell of! I’ve had enough of buying stuff to get the old stock** A: I can’t answer as I bought mine in 2018! However, if the product differs from the advertised image then you must be entitled to a full refund. **Q: Are these pliers the older model with the red plastic jaw inserts or the newer model with the blue and red inserts? Both types are illustrated.** A: Mine is all red jaw inserts. However I bought mine in 2018 so speck may be different now. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great πŸ‘ *by N***N on 6 February 2026* Great quality pliers like all Knipex products, definitely recommend. ### ⭐⭐⭐⭐⭐ Superb *by L***A on 12 May 2026* Good quality ### ⭐⭐⭐⭐ Great tool as expected. *by J***O on 3 January 2026* Excellent tool, as to be expected by knipex. Good size for multiple sizes, good grip and adjustability. One slight niggle considering the price, surprised it only came in a plastic bag. I know it was saving the environment and it does not detract from the tool, as my wife said does it stop the tool working? Of course not, get a life.
