Zoro Select 404E111N012 1/2 in FNPT 304 Stainless Steel 45° Elbow Class 150 equipment

SKU CH-Z4JG-84P02

304 stainless steel 45° elbow with 1/2 in FNPT ends, Class 150 rated to 300 psi for air, gas, water, oil and steam

  • 304 stainless steel resists corrosion in water, oil, gas and steam systems
  • 45° elbow redirects flow smoothly through 1/2 in FNPT threaded connections
  • Class 150 rating handles up to 300 psi working pressure for industrial use
  • Meets ASTM A351, ASME B1.20.1 and MSS SP-114 standards for reliable installation
  • Low-lead compliant for potable water and Schedule 40 pipe compatibility

1/2 in FNPT 45° Elbow

This 1/2 inch FNPT 45° elbow redirects flow in piping systems using 304 stainless steel. It serves installers who need a corrosion-resistant fitting for air, natural gas, oil, potable water, non-potable water or steam. The female NPT threads on both ends accept Schedule 40 pipe of the same nominal size.

Sustained pressure performance

The fitting meets MSS-SP-114 Class 150 standards and is rated for a maximum operating pressure of 300 psi. Material conformance to ASTM-A-351 and thread conformance to ANSME B1.20.1 support consistent sealing under continuous rated pressure rather than only during brief test spikes.

Class 150 interface limits

Class 150 rating defines the pressure boundary at 300 psi for compatible media including steam. The 1/2 inch FNPT thread form and Schedule 40 pipe schedule set the mechanical envelope; the fitting does not accommodate larger nominal sizes, different thread standards or pressure classes beyond Class 150.

Questions about this item

Does the 304 stainless steel 45° elbow generate heat or noise when steam runs through it continuously?

The 304 stainless steel fitting itself has no moving parts and produces no noise; it simply conducts the fluid temperature, so surface heat will match the steam temperature within the 300 psi Class 150 rating.

What pipe schedule and thread standard must the existing piping meet to connect to the 1/2 in FNPT ends?

The elbow is compatible with Schedule 40 pipe and conforms to ANSME B1.20.1 for the 1/2 inch female NPT threads on both ends.

Will this Class 150 elbow mate with older 300 psi rated fittings already in the system?

It is rated for a maximum operating pressure of 300 psi under MSS-SP-114 Class 150 standards, so it can join higher-rated components only if the system pressure never exceeds 300 psi.
