Value Brand 3/8" x 7" Black Pipe Nipple Sch 40

SKU CH-K6XC-ZC79B

A Schedule 40 black steel pipe nipple with threaded ends for 300 psi water or 150 psi steam service

  • Schedule 40 rated for 300 psi water pressure
  • Threaded MNPT both ends for direct connection
  • Electric resistance welded seam for strength
  • Black steel construction resists corrosion
  • Meets ASTM A-53 Type E and A-733 Grade B standards

Black Steel Pipe Nipple 3/8 Inch

This 3/8 inch nominal black steel pipe nipple measures 7 inches overall and features male NPT threads on both ends. It is manufactured to Schedule 40 wall thickness using electric resistance welding and conforms to ASTM A-53 Type E and ASTM A-733 Grade B standards.

Suited for Standard Pressure Piping

The nipple handles a maximum pressure of 300 psi at 150 degrees Fahrenheit and a maximum steam pressure of 150 psi, making it appropriate for typical water, gas, and steam distribution lines. Installers needing higher pressure ratings, different pipe diameters, or alternative materials such as galvanized or stainless steel should select a different fitting.

Capacity and Pressure Headroom

With a 5/64 inch wall thickness and 43/64 inch outside diameter, the fitting provides reliable service within its rated pressure and temperature limits. It reaches its design limit at the stated maximum pressures, so systems operating beyond 300 psi or 150 psi steam require heavier schedule pipe or alternative connection methods.

Highlights

  • Threaded MNPT both ends for direct connection

Questions about this item

What thread type does the 3/8 inch pipe nipple need on the mating fittings?

The nipple has MNPT threads on both ends, so the connecting fittings must accept male NPT threads of the same nominal size.

Can the Schedule 40 nipple handle the pressure from my existing 150 psi steam system?

Yes, the nipple is rated for 150 psi steam working pressure, matching the maximum steam pressure of your current system.

How do I confirm the 300 psi pressure rating is valid after installation?

Pressure-test the assembled line to the system design pressure and inspect every threaded joint for leaks; no leaks confirms the rating holds.
