Hawle reducer coupling Synoflex 7974 DN350-DN300 PN10

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

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. With an EPDM gasket on both sides, the coupling reducer coupling is suitable for drinking water up to PN10. 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 350 and has a size range from a minimum of 352 mm to a maximum of 396 mm. The other connection is DN 300 and has a size range from a minimum of 313 mm to a maximum of 356 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 unique design of the grip ring distributes pressure evenly across the pipe, resulting in minimal 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. Furthermore, the Synoflex reducing coupling is capable of accommodating an angular deflection up to 8° (2x 4°) over the entire size range.
