Value Brand Malleable Iron 45 Degree Elbow Class 300 2 in FNPT

2 in FNPT 45 Degree Elbow

This malleable iron elbow connects two-inch female NPT threads at a 45-degree angle. It is rated Class 300 for saturated steam service up to 300 psi and handles pressures up to 1500 psi at 150 degrees F. The fitting meets ASME B16.3, B16.4, ASTM A197 and ASTM A47 standards with FM and UL listings. It suits plumbing and industrial piping systems requiring a directional change.

Sustained pressure and temperature performance

The body withstands continuous operating temperatures from -20 to 550 degrees F without degradation. At the upper end of this range the 300 psi steam rating applies, while the 1500 psi structural limit is referenced at 150 degrees F. Malleable iron construction resists shock and vibration in permanent installations. The threaded FNPT joints maintain seal integrity through thermal cycling.

Replaces lower-class or damaged elbows

This fitting upgrades from Class 150 components when system pressure or steam temperature exceeds the lower rating. It also serves as a direct replacement for corroded or cracked malleable iron elbows in existing two-inch NPT piping. The jump is worth it when design pressure approaches 300 psi saturated steam or when codes require ASME B16.3 compliance. Not for systems using press-fit, grooved or welded connections.
