4 in x 2 in Malleable Iron Hex Bushing

This hex bushing reduces a 4 in male NPT thread to a 2 in female NPT thread for pipe-size transitions in plumbing systems. It is built from malleable iron rated to Class 150 for durability in water, oil, air and saturated steam service. The fitting suits installers who need a single-piece reducer that meets recognised piping standards.

Installation uses standard NPT threading practice

Apply thread sealant or tape to the male threads and tighten to the recommended engagement for a leak-free joint. Over-tightening can crack the iron casting, while under-tightening leaves a spiral leak path. The hex head provides a solid wrench surface, but the fitting is not intended for applications that require frequent disassembly.

Pressure and temperature limits define the safe

The bushing is rated for 300 psi at 150 °F and 150 psi saturated steam, with an operating range of -20 °F to 366 °F. Systems that exceed these pressures or temperatures need a higher-class fitting. Buyers who need a larger reduction or a different thread standard must select another part.
