Anvil 0310508601 1-1/2 in 90 Degree Street Elbow Class 300 Malleable Iron

Built for Pressurised Piping

The Anvil 0310508601 is a 90-degree street elbow machined from malleable iron and rated Class 300 for demanding fluid systems. It joins a female NPT thread to a male NPT thread in a 1-1/2 inch pipe size, redirecting flow in tight runs where a standard elbow cannot reach. The fitting carries AAR, FM and UL listings and meets ASME B16.3, so specifiers can document compliance without extra paperwork. It suits installers who need a single, code-accepted corner in steam, air or hydraulic circuits.

Fits Between Threaded Components

The FNPT x MNPT connection lets the elbow screw directly into a female-threaded fitting on one side and accept a male-threaded pipe or nipple on the other, eliminating an extra coupling. This reduces leak paths and shortens the overall assembly length in crowded mechanical rooms. Malleable iron withstands mechanical shock and vibration better than cast iron, so the joint stays tight when nearby equipment cycles on and off. No special tools beyond standard pipe wrenches are required for installation.

Holds Rating Through Thermal Cycles

The elbow is rated for 1500 psi at 150 degrees F and 300 psi saturated steam at 550 degrees F, with a continuous service range from -20 to 550 degrees F. These limits apply to sustained pressure and temperature, not momentary spikes, so the fitting remains within its design envelope during long steam-header runs or extended chiller shutdowns. Malleable iron’s ductile microstructure resists brittle fracture when the system cools rapidly after prolonged heat exposure. Inspectors recognise the UL and FM marks as evidence of ongoing compliance.
