Primofit® Firejoint Coupling - 1.1/4”

The PRIMOFIT® firejoint system uses the same casting bodies and nuts as the standard system, the main difference is the inclusion of a graphite seal.

The seal is not affected by the heat that it could be subjected to during a fire. Its main purpose is to maintain the end load capability of the joint if the rubber seal degrades during a fire thus providing a sound joint both during and after a fire.

Under test conditions at 75 mbar, 40°C working temperature, the joint must withstand a temperature of 850°C for 30 minutes. For Natural Gas laterals and riser sinside and outside buildings.

The system was specifically designed to enable gas to be supplied to blocks of flats or apartments up to a 40 metre riser height without the need for conventional screwed or welded joints.

Approvals - British Gas for internal and external use on above-ground steel gas pipes - DIN-DVGW (HTB).Made by a BS EN ISO 9001 registered company.

All fittings galvanised.

For Natural Gas and LPG.
