90° Elbow Malleable Iron 3/4" NPT Class 150

This galvanised malleable iron elbow provides a 90 degree change of direction in piping systems. It features 3/4 inch female NPT threads on both ends for secure connections. The fitting meets Class 150 pressure rating requirements for standard plumbing installations. Suitable for residential and commercial pipework projects.

Class 150 pressure rating and NPT threading

Class 150 designates the maximum working pressure for this fitting under standard conditions. The 3/4 inch NPT threads require proper sealant or tape to prevent leaks during assembly. Malleable iron construction offers mechanical strength but is not intended for high-corrosion environments without additional protection. California Proposition 65 warnings apply due to chemical content.

Galvanised malleable iron capacity and limits

The galvanised coating provides a baseline level of corrosion resistance for water and air lines. It comfortably handles typical residential supply pressures within the Class 150 rating. The material reaches its limit in highly acidic, saline or chemically aggressive fluids where the zinc layer degrades rapidly. Not designed for potable water systems requiring lead-free certification.
