SKU CH-5FM2-HD2JH

Threaded galvanised steel nipple, Schedule 40, rated 300 psi at 150 °F

  • Threaded both ends for quick assembly
  • Schedule 40 wall rated to 300 psi at 150 °F
  • Galvanized steel resists corrosion in water lines
  • Electric-resistance welded seam meets ASTM A-53 Type E
  • California Proposition 65 warning for cancer and reproductive harm

Threaded Galvanized Steel Nipple

This 1/2 inch nominal pipe nipple is threaded on both ends with male NPT connections for joining two female-threaded fittings in water, air or gas lines. The welded Schedule 40 galvanized steel construction meets ASTM A-53 Type E and ASTM A-733 Grade B standards for pressure piping applications. It is suited for plumbers, maintenance technicians and DIY installers who need a standard-length threaded connector.

California Proposition 65 Compliance

The product carries a Proposition 65 warning for chemicals known to the State of California to cause cancer and birth defects or other reproductive harm. This regulatory notice does not alter the fitting’s mechanical function or pressure rating but informs buyers of the statutory disclosure requirement. Installers should follow local codes and safety-data-sheet guidance when handling the nipple.

300 psi at 150 Degrees F Rating

The maximum working pressure of 300 psi at 150 degrees Fahrenheit is the single specification that determines whether this nipple matches the system design pressure. Verify that the operating pressure and temperature of the intended line fall within this limit before selecting the part. Systems exceeding this rating require a higher-class fitting.

Questions about this item

How often should the galvanized coating on this 1/2" Schedule 40 nipple be inspected for wear?

Inspect the zinc coating periodically for white rust or red rust, especially at the threads; replace the nipple once the steel substrate is exposed to prevent leaks.

What pressure limit applies when this nipple runs continuously at 150 °F?

The maximum working pressure is 300 psi at 150 °F; sustained operation above that temperature or pressure will exceed the Schedule 40 rating.

Does the electric-resistance-welded seam affect heat dissipation during all-day hot-water service?

The ERW seam meets ASTM A-53 Type E and conducts heat uniformly with the parent tube; no additional thermal resistance is introduced at 300 psi service.
