The National Brand pipe fittings threads are machined according to the highly accurate American or British standards. It is difficult to label either type thread for fittings as more desirable in practice. The National Brand can deliver fittings with either parallel or taper threading upon client specifications or requirements. Elaborate chamfering of the threaded end allows the pipe fitting to be attached to the pipe easily and smoothly. Breakage around the joint is exceedingly rare.

In addition to threaded fittings, we can also offer fittings for socket weld applications in 90 O Elbow, 45 O Elbow, Tee, Crossed, Caps, Reducing Tee, Reducing Elbow, Union and Couplings.
