Our GT-fittings in composite material are threaded fittings for connecting with the use of hemp, tape or equal. Liquid paste can also be applied. The GT-fittings are cylindrical threaded fittings, male and female from 3/4”- 2”. Because the parts are made from composite material they are not electrically conductive, and can be used as an isolator between two different types of metal to avoid galvanic corrosion. If electrical conduction is desirable, our brass threaded fittings may be used instead.
