Our Hawle ISO fittings and service valves made of robust ductile cast iron are as diverse as the many and varied installation scenarios. For decades, our motto has been “nothing is impossible” and this has always proven to be true. We have the appropriate and secure special fitting variant for every house connection. This saves time and money in the long term because they can be reused. Hawle's durable and proven fitting solutions are bound to impress as they are also easy and quick to install.
The ZAK system from Hawle enables tapping saddles, valves and fittings to be connected quickly and easily. The so-called "bayonet connection" is simple and can be installed in seconds and disassembled and reused just as quickly if necessary. Producing reliable threadless connections for water and sewage pipeline valves and fittings has never been easier. They are flexible, 100% leak-proof and corrosion-resistant even at 16 bar pressure, making them exceptionally durable.
Features
ISO-socket:
The function of the ISO pipe fitting is clear and simple: the O-ring made of highly elastic elastomer seals even when depressurized due to its pretension on the pipe.
As the water pressure and pipe tension increase, the sealing and grip rings are compressed further into the conical chamber, thus increasing the sealing and gripping effect
The gripping and sealing functions only act on the outer diameter of the pipe; therefore only one fitting is required for all pressure ratings up to PN 16
All ISO pipe fittings can also be supplied for PVC pipes with a spezialised grip ring at extra cost.
