TORF Fittings

WorldWide Machining & Welding, Inc., has developed a single-bodied TORF (Thread-O-Ring, Flanged) Fitting with integral reinforcement.

This NEW single-body design reduces the number of welds required during the manufacturing process. The elimination of the weld between the main body and the weld-o-let reduces manufacturing costs and increases the overall strength of the TORF.

Field Application

TORF Fittings can be used in a variety of applications, such as for purge and equalization during drain-up operations. TORF Fittings are fully compatible with current hot tapping machines, thermometer wells, gauge adapters and other probe instrumentation devices.
