The right solution for all situations: this has been our requirement of Hawle ISO fittings and service valves made of POM since 1968. The fact that they can be reused makes them the perfect, affordable and safe solution for any temporary or fixed water supply connection. ISO POM fittings are quick and easy to install, while ensuring the highest levels of safety, reliability, and durability. After all, when it comes to water supply connections, we settle for nothing less.
Features
For PE pipes according to EN 12201-2 and DIN 8074, up to PN 16
The HAWLE ISO pipe fitting is the easiest way joining polyethylene pipes
The ISO pipe fitting is suitable for use in drinking water area up to a temperature of 30 °C
The gripping and sealing functions act only the o.d. of the pipe; thereforce only one fitting is required for all pressure ratings up to PN 16
The function of the ISO pipe fitting is clear and simple; the O-ring is made of elastomer and seals well even when the pressure is nil, because it is compressed onto 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 joint is flexible and the fitting can be turned on the pipe without affecting the grip or seal. Assembly the fitting is quick and simple and can be dismantled if required.
This design has been well proven for many years in water distribution and is used in pipelines with pressures up to PN 16 (also in vacuum situations, with support liner)
In POM fittings all internal threads are strengthened with a stainless steel ring
