Hawle reducer coupling Synoflex 7974 DN250-DN225

Due to dimensional and compatibility issues with couplings, it can be difficult to properly connect non-dedicated pipes, such as cast iron or AC. These challenges are addressed by Hawle's Synoflex series, which is designed to connect, for example, older pipes, such as cast iron or asbestos cement, to modern pipes such as PE and PVC. Furthermore, they are quick, safe and easy to install and have a long lifetime. Its versatility makes Hawles Synoflex an indispensable coupling, resulting in significant savings in time and costs.

Application

The Synoflex coupling can be used on a wide range of pipe materials, including steel, PE, PVC, steel, cast iron and AC (AC restraint is not guaranteed), in accordance with EN 14525. This coupling is equipped with an EPDM gasket on both sides, making it suitable for drinking water up to PN16. This Synoflex reducing coupling is a restraint coupling, which is designed to connect pipes with different outer diameters. One connection of the coupling is DN 250 and has a size range from a minimum of 265 mm to a maximum of 310 mm. The other connection is DN 225 and has a size range from a minimum of 230 mm to a maximum of 260 mm.

Product Features

The Synoflex reducing coupling is designed to meet the requirements of EN 14525. The Synoflex reducing coupling is made of ductile iron with an epoxy powder coating. This makes the coupling resistant to abrasion or significant damage from chemicals or corrosion. 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. Furthermore, the Synoflex reducing coupling is capable of accommodating an angular deflection up to 8° (2x 4°) over the entire size range.
