Value Brand

Value Brand 3 in 90 Degree Elbow Class 300 Malleable Iron coupling

SKU CH-QJDG-RFQDG

A malleable-iron 90-degree elbow with FNPT threads, rated Class 300 for 1000 psi at 150 °F and 300 psi saturated steam, meeting ASME B16.3, B16.4, ASTM A197 and A47 with FM and UL approval

  • Directs flow at 90 degrees with malleable iron strength
  • Rated for 1000 psi at 150 degrees F service pressure
  • Handles saturated steam up to 300 psi safely
  • Operates from -20 to 550 degrees F temperature range
  • Meets ASME B16.3 B16.4 ASTM A197 A47 FM UL standards

Built for High-Pressure Steam Lines

This malleable iron elbow carries a Class 300 rating and handles saturated steam at 300 psi. It is intended for plant engineers and pipefitters who need a 90-degree turn in systems that see elevated temperature and pressure.

Rated for Extreme Temperature Range

The fitting operates from -20 to 550 degrees F and withstands 1000 psi at 150 degrees F. Malleable iron construction meets ASME B16.3 and B16.4 plus ASTM A197 and ASTM A47 for consistent strength across thermal cycles.

FM Approved and UL Listed for Code Compliance

Third-party certifications satisfy insurance and inspector requirements on commercial steam and water installations. The FNPT threads seal with standard pipe dope or tape without proprietary tooling.

Questions about this item

How do I install the 3-inch FNPT elbow and what step is often missed?

Clean the male threads, apply PTFE tape or pipe dope, thread the elbow on by hand, then tighten with a pipe wrench; the step often missed is fully engaging all threads before final torque to prevent leaks at 1000 psi.

What maintenance or replacement will this Class 300 malleable iron elbow need over time?

Inspect annually for corrosion, cracking, or thread deformation; replace if leaks appear or if the fitting has been exposed to temperatures beyond the -20 to 550 °F range or pressures above 1000 psi.

What limit appears first when this elbow runs continuously at high temperature and pressure?

The saturated steam limit of 300 psi is reached before the 1000 psi water rating, so sustained steam service above 300 psi will exceed the design envelope first.
