Anvil 311090005 Malleable Iron Straight Coupling 2 1/2 NPT x 2 NPT

SKU CH-E8CV-K9W53

A galvanised malleable-iron straight coupling joining 2 1/2 in NPT to 2 in NPT female threads, rated Class 150 for Schedule 40 pipe at 300 psi and 150 °F

  • Malleable iron construction resists corrosion in demanding plumbing systems
  • Galvanized finish protects against rust for longer service life
  • Class 150 rating handles 300 psi at 150 °F operating conditions
  • Schedule 40 compatibility fits standard piping installations
  • Reducing design joins 2 1/2 in NPT to 2 in NPT threads

Straight coupling for reducing pipe sizes

This malleable iron coupling joins a 2 1/2 inch NPT female thread to a 2 inch NPT female thread in a straight configuration. It is galvanized for corrosion resistance and rated Class 150 for Schedule 40 piping systems. The fitting suits installers who need a direct reduction between these two nominal sizes.

Pressure and temperature limits defined by class

The Class 150 designation sets a maximum operating pressure of 300 psi at 150 degrees Fahrenheit. Performance declines as temperature rises above this reference point, so the fitting must not be used beyond the rated pressure-temperature curve. It is not intended for high-pressure hydraulic lines or steam service exceeding the class limit.

Galvanized malleable iron with threaded ends

The galvanized coating protects the malleable iron body during handling and in damp environments. Both ends use standard NPT female threads, requiring pipe tape or sealant for a leak-free joint. The straight body keeps the pipe run linear, which simplifies alignment in tight trenches or against walls.

Questions about this item

Should I choose the 2 1/2 inch or 2 inch end first when planning the pipe run?

Both ends are female NPT threads; the coupling joins a 2 1/2 inch pipe to a 2 inch pipe in either direction, so choose based on which pipe you are connecting to each side.

What does the Class 150 rating mean for daily water pressure at 150 °F?

Class 150 malleable iron is rated for 300 psi at 150 °F, so normal municipal or pumped water systems at that temperature stay well within the limit.

Will the NPT threads seal directly on Schedule 40 pipe without extra adapters?

Yes, the female NPT threads are cut for Schedule 40 pipe; apply thread sealant and tighten to make a pressure-tight joint up to the 300 psi rating.
