Knipex 90 25 20 is a hand-operated pipe cutter for multi-layer composite pipe, 210 mm long overall, with multi-component grips for controlled cutting effort. The precision-ground blade produces a square, burr-free cut suitable for push-fit and compression fittings. It is engineered for repeated shop-floor and on-site use in domestic water, radiator and underfloor heating installations. Typical application is preparation of PEX-AL-PEX composite pipe by plumbers and heating installers.
