Value Brand

Value Brand 1/2" MNPT x MNPT Black Steel Close Pipe Nipple Schedule 80

SKU CH-4CDD-0YN3G

Schedule 80 black steel close nipple with MNPT threads on both ends, rated 2000 psi at 150 °F

  • Schedule 80 wall handles 2,000 psi at 150 °F
  • Seamless black steel meets ASTM A106 and A733 standards
  • MNPT threads on both ends for direct pipe connection
  • 300 psi steam rating at 550 °F for high-temp lines
  • ANSI/ASME B1.20.1 threads ensure leak-tight seal

Application and Purpose

This black steel close nipple connects two female NPT ports in hydraulic, pneumatic or steam systems. It suits installers and maintenance teams who need a short, rigid link rated for high-pressure service.

Build and Connection

The Schedule 80 seamless tube has a 9/64 in wall and 53/64 in outside diameter for mechanical strength. Both ends carry MNPT threads to ANSI/ASME B 1.20.1 so the joint seals without welding or flanges.

Pressure and Temperature Limits

Rated 2000 psi at 150 degrees F and 300 psi steam at 550 degrees F per ASTM A106 and A733. The heavy wall contains pressure spikes while the steel body resists thermal cycling in normal industrial use.
