3/4" Malleable Iron Street Elbow

This 90-degree street elbow connects a 3/4 inch female NPT thread to a male NPT thread. It is made from malleable iron rated to Class 300 and meets ASME B 16.3, B 16.4, ASTM A-197 and ASTM A47 standards. The fitting carries FM Approved and UL Listed markings for code-compliant installations.

Suits threaded pipe runs needing a tight 90-degree

Plumbers and maintenance crews working with water, oil, air or saturated steam lines up to 300 psi will find the pressure and temperature ratings cover most commercial jobs. Installers who require a different thread type, a larger pipe size or a lower pressure class should select another fitting.

Handles up to 2000 psi at 150 °F

The malleable iron body operates continuously from -20 °F to 550 °F, giving ample headroom for heating systems and process piping. At the upper end of the temperature range the allowable pressure drops, so designers must consult the applicable ASME pressure-temperature tables for their specific service conditions.

Questions about this item

What pipe size and thread type does the 3/4 inch malleable iron street elbow need to connect to?

The elbow has a 3/4 inch pipe size with FNPT x MNPT connection threads, so it joins a female NPT fitting on one end and a male NPT fitting on the other.

Will this Class 300 street elbow handle the same pressure as my existing Class 150 malleable iron fittings?

This fitting is rated for 2000 psi at 150 degrees F and 300 psi saturated steam, which is higher than Class 150 ratings, so it will not be the limiting factor in a mixed system.

How can I confirm the elbow meets code after I install it?

The body carries ASME B16.3 and B16.4 markings plus FM Approved and UL Listed stamps, and the malleable iron meets ASTM A197 and ASTM A47 standards for verification.
