Schedule 40 black steel nipple with threaded ends for 150 psi water or steam service

  • Schedule 40 wall rated for 150 psi service

  • Black steel construction meets ASTM A53 Type F
  • Continuous weld seam tested to ASTM A733 Grade A
  • 5 in overall length fits standard 3 in nominal pipe

3-inch Schedule 40 pipe nipple

This 3-inch nominal black steel nipple measures 5.5 inches overall and is threaded with MNPT connections on both ends. It conforms to ASTM A-53 Type F and ASTM A733 Grade A standards for welded pipe fittings. The continuous weld construction suits standard plumbing and low-pressure steam installations.

Rated for 150 psi and 150 psi WSP at 360 degrees F

The maximum working pressure of 150 psi and identical steam rating at 360 degrees F define the safe operating envelope for this fitting. Exceeding either pressure or temperature limit risks joint failure and leaks. Verify system pressure and steam temperature before specifying this nipple.

Threaded both ends for direct assembly

MNPT threads on each end allow the nipple to screw straight into female-threaded fittings, valves or equipment without adapters. Apply suitable pipe thread sealant or tape to prevent leaks at the joints. Ensure mating threads are clean and undamaged; cross-threading or over-tightening can crack the fitting or strip the threads.

Questions about this item

What does Schedule 40 mean once the nipple is installed?

It indicates a standard wall thickness for 3-inch nominal pipe, giving a 150 psi pressure rating and 150 psi steam rating at 360°F.

How do the MNPT threads on both ends limit what I can connect?

They accept female NPT fittings only; the tapered threads seal with thread sealant and cap the joint at the 150 psi rating.

What clearance is needed to fit the 5.5-inch overall length?

The nipple measures 5.5 inches end to end, so allow at least that much straight run plus thread engagement on each side.
