Hawle coupling Synoflex 7974 DN050 56/71 mm

Due to dimensional issues and coupling compatibility, connecting non-dedicated pipes such as cast iron and AC can be challenging. Hawle addresses these challenges with the Synoflex series, which is specifically designed to connect older pipes such as asbestos cement or cast iron to modern pipe materials such as PE and PVC. Furthermore, Synoflex is quick, safe and easy to install and has a long lifetime. This makes the Hawle Synoflex an all-round coupling that can save you both time and money.

Application

In accordance with EN 14525, Synoflex couplings can be used with a variety of pipe materials including steel, PE, PVC, steel, cast iron and AC (AC restraint cannot be guaranteed). The Synoflex coupling is restraint and is designed to connect pipes with different outside diameters. The connection of this coupling is DN 50 and has a size range from minimum 56 mm to maximum 71 mm on both sides. This coupling is equipped with a EPDM gasket on both sides, making it suitable for drinking water up to PN16.

Product Features

Thanks to the ductile iron housing with an epoxy powder coating, the Synoflex coupling offers long-term resistance to abrasion or damage caused by corrosion or chemicals. The grip ring ensures that the pressure is evenly distributed over the pipe, resulting in minimal constriction on the pipe, a unique feature compared to other couplings on the market. An additional advantage is that the Synoflex couplings do not require support liners for PE pipes with an SDR class of <21. Synoflex couplings have an angle of deflection of 8° (2x 4°) over the entire size range of the coupling.
