Hawle coupling Synoflex 7974 DN080 85/105 mm

Due to dimensional and compatibility issues with couplings, 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 easily connect, for example, older pipes, such as asbestos cement or cast iron, to modern pipe materials, such as PE and PVC. Installation is quick, safe and easy, and Synoflex also has a long service life. With their versatility and ability to save time and money, Hawle Synoflex couplings are an indispensable product.

Application

In accordance with EN 14525, Synoflex couplings are compatible with a variety of pipe materials including steel, PE, PVC, 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 80 and has a size range from minimum 85 mm to maximum 105 mm on both sides. In addition, this coupling has a gasket made of EPDM on both sides and is therefore suitable for drinking water up to PN16.

Product Features

To prevent abrasion or significant damage from chemicals or corrosion, Synoflex couplings are made of ductile iron with an epoxy powder coating. The unique design of the grip ring distributes pressure evenly across the pipe, resulting in the least constriction on the pipe compared to other fittings 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.
