Value Brand 3/8" x 4" Black Pipe Nipple Sch 80

SKU CH-PNBW-26Y8N

Seamless black steel pipe nipple with threaded ends, rated 2000 psi at 150°F and 300 psi steam at 550°F

  • Schedule 80 wall handles 2000 psi at 150 °F
  • Black steel construction resists corrosion in harsh environments
  • Seamless design eliminates leak paths under pressure
  • Threaded both ends for direct MNPT-to-MNPT connection
  • Meets ANSI/ASME B1.20.1 and ASTM A106 standards

3/8" Schedule 80 Pipe Nipple

This seamless black steel nipple connects two female NPT fittings in high-pressure piping systems. Its Schedule 80 wall withstands up to 2000 psi at 150 degrees F and 300 psi steam at 550 degrees F. The 4-inch overall length suits compact industrial or commercial installations.

Verify Thread Compatibility And Pressure Rating

Confirm that both mating ports use MNPT threads to match the nipple's male ends. Ensure the system design pressure does not exceed the 2000 psi rating at the operating temperature. Check that the 3/8-inch nominal bore provides adequate flow for the intended application.

Seamless Black Steel Construction

The seamless ASTM A106 pipe body eliminates weld seams that could leak under cyclic pressure. Threads conform to ANSI/ASME B1.20.1 for reliable sealing with standard tape or compound. The 43/64-inch outside diameter and 1/8-inch wall thickness meet ASTM A733 dimensional tolerances for consistent fit.

Questions about this item

What comes in the box and do I need any extra fittings?

The box contains one seamless black steel pipe nipple with male NPT threads on both ends; no additional fittings are included, so you will need to supply any couplings, valves or sealant required for your installation.

Which schedule rating should I choose for a 2000 psi water line at 150 °F?

This nipple is Schedule 80, rated for 2000 psi at 150 °F and 300 psi steam at 550 °F, making it suitable for high-pressure water service at that temperature.

How does the 43/64 inch outside diameter affect fitting compatibility?

The 43/64 inch outside diameter matches standard 3/8 inch nominal pipe size, so it threads directly into any ANSI/ASME B1.20.1 compliant female NPT fitting without adapters.
