Value Brand 1/2" x 9" Black Pipe Nipple Sch 40

SKU CH-9QXC-2M0MD

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

  • Schedule 40 wall rated for 300 psi at 150 °F
  • Electric-resistance welded black steel meets ASTM A-53 Type E and A-733
  • Threaded MNPT both ends for direct pipe connection
  • 9-inch overall length with 53/64-inch outside diameter
  • Grade B construction certified to WWN 351 standard

Black Steel Pipe Nipple

This 1/2 inch nominal pipe nipple is made from black steel and measures 9 inches overall. It is threaded on both ends with MNPT connections for joining two female fittings. The Schedule 40 wall thickness is 3/32 inch and the outside diameter is 53/64 inch. It meets ASTM A-53 Type E, ASTM A-733, Grade B and WWN 351 standards.

Pressure Ratings and Limits

The fitting handles a maximum pressure of 300 psi at 150 degrees Fahrenheit and a maximum steam pressure of 150 psi WSP. These ratings define the safe operating envelope for water, air, oil or steam lines. Exceeding either pressure or temperature limit risks joint failure or leakage. The welded electric resistance construction provides consistent strength along the barrel.

Threaded Connection Constraints

The MNPT x MNPT threads require compatible female NPT ports and proper sealant to prevent leaks. Over-tightening can crack the fitting or the mating component because tapered threads generate high radial stress. The nipple is not suited for systems requiring flange, grooved or press-fit connections. It cannot be used where a union or flexible coupling is needed for maintenance access.

Questions about this item

Will the 1/2 inch MNPT threads on this Schedule 40 nipple match the fittings on my existing black steel piping?

Yes, both ends are cut to MNPT standard threads so they screw directly into any 1/2 inch female NPT fitting you already have.

How can I verify the nipple is rated for the 300 psi / 150 °F service marked on the spec sheet?

Look for the ASTM A-53 Type E and Grade B markings stamped on the pipe body; they confirm the 300 psi at 150 °F pressure rating.

Does the 9 inch length include the threaded portions, and are any sealants or gaskets packed with the nipple?

The 9 inch overall length is measured end-to-end including threads; the box contains only the bare steel nipple, so you must supply thread tape or pipe dope separately.
