45-Degree Malleable Iron Street Elbow

This Zoro Select fitting redirects pipe runs by 45 degrees in plumbing systems. It connects a 1-1/2 inch female NPT thread to a 1-1/2 inch male NPT thread. The Class 300 malleable iron construction suits water, oil, gas and air lines. Installers use it where a gradual direction change is required.

Sustained Pressure and Flow Performance

The Class 300 rating defines the pressure envelope the elbow maintains during continuous service. Malleable iron resists deformation under steady hydraulic loads better than lower-class fittings. The 45-degree sweep reduces turbulence compared to sharp bends, preserving flow efficiency over long operating periods. Thread engagement to the 11-1/2 NPT standard maintains seal integrity through thermal cycles.

Class 300 Pressure Rating Decides Suitability

The single specification that determines fit is the Class 300 pressure rating matched to your system design pressure. If the piping circuit operates above this class, the elbow is not the right part regardless of thread size. Conversely, systems rated for lower classes can use this fitting with a safety margin. Verify the design pressure against Class 300 before specifying.

Questions about this item

How much heat does the malleable iron elbow radiate when hot water runs through it all day?

Malleable iron conducts heat, so the fitting will become warm; insulate the pipe run if surface temperature is a concern.

What thread sealant or tape is needed for the 11 1/2 NPT threads on this fitting?

Use PTFE tape or pipe dope rated for NPT threads to seal the 11 1/2 threads on both the male and female ends.

Will the 1-1/2 inch NPT ends match the 1-1/2 inch NPT nipples and couplings already in my system?

Yes, both ends are 1-1/2 inch NPT with 11 1/2 threads per inch, so they connect directly to existing 1-1/2 inch NPT components.
