Hawle flange adapter Synoflex 7994 DN400 398-442 mm 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

PE80/100 pipes (according to EN 12201) are compatible with 7994 flange adapters. The Synoflex flange adapter can be connected to various pipe materials, such as steel, PE, PVC, steel, cast iron, and AC, in accordance with EN 14525 (AC restraint cannot be guaranteed). The flange bore is according to EN1092 PN10. This flange adapter has a DN 400 flange on one side and has a restraint, wide range connection of DN 400 on the other side. The size range of this connection is minimum 398 mm to maximum 442 mm. With a gasket of EPDM, the flange adapter is suitable for drinking water up to PN10.

Product Features

To prevent abrasion or significant damage from chemicals or corrosion, Synoflex flange adapters are made of ductile iron with an epoxy powder coating. 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 a support liner for PE pipes with an SDR class of <21. Furthermore, within the entire size range of the Synoflex coupling, an angular deflection of up to 4° is possible.
