3/4 inch Black Iron 90 Degree Street Elbow Female x Male

3/4 inch Black Malleable Iron Street Elbow – 90° FPT x MPT

The 3/4 inch Black Malleable Iron 90-Degree Street Elbow is engineered for directional changes in threaded piping systems. Featuring a female pipe thread (FPT) on one end and male pipe thread (MPT) on the other, this elbow enables compact installations without the need for additional fittings. It is ideal for creating offsets in systems where space constraints are a factor.

Manufactured in accordance with ASTM A197 for malleable iron castings and conforming to ASME B16.3 dimensional standards, this fitting is pressure-rated for both residential and commercial applications including steam, water, air, and gas lines. The black iron finish provides basic corrosion resistance in dry indoor conditions and is commonly used in fire protection, HVAC, and fuel oil systems.

Key Features

• ✅ Material: Malleable iron for excellent mechanical strength and ductility
• ✅ Connection Type: FNPT x MNPT – Female and Male National Pipe Threads
• ✅ Angle: 90 degrees for precise directional change
• ✅ Finish: Black (non-galvanized), intended for non-potable systems

Installation Guidelines

Threaded installation requires proper thread preparation to ensure a leak-tight seal. Use a certified thread sealant or PTFE tape rated for the intended media and temperature range. Do not overtighten, as excessive torque may cause thread deformation or fitting damage. Always verify compatibility with system materials and local mechanical/plumbing codes.
