Acu-Tech compression fittings and clamp saddles are designed specifically for connecting polyethylene pipes with an outside diameter from 16 mm to 110 mm (200 mm for clamp saddles). They are compatible with PELD, PEHD, PE40, PE80 and PE100 pipes complying with AS / NZS 4130 Series 1. They are normally used to convey drinking water and fluids at pressures up to 16 bar for generic applications. The quality of the materials used makes these Plasson fittings resistant to etching by numerous chemical substances, and to UV-rays. The Acu-Tech Universal Fitting can be used to connect systems using PE metric piping with existing pipes made of any material, with external diameters of 15-34 mm. Acu-Tech compression fittings are very similar in design to SAB compression fittings, Plasson compression fittings and Philmac compression fittings, which are designed around similar poly pipe joining principles.
