Ravetti™ original fittings are built entirely in from specific materials designed for low temperatures (up to - 46°C ), therefore they can be used within a large temperature range.
The material used is also characterised by a low content of carbon equivalent, in order to facilitate welding.
The fittings are supplied with o-ring seals in NBR70 as standard version, while a specific o-ring rubber is provided for district heating.
For easier use, the first part of the internal thread is removed from the fittings in order to screw the completion cap more easily into the fitting.
The fittings up to 5" are PN 40, while from 6" to 12" they are PN 20
