Description
300# Extra Heavy Black Malleable Iron 90° Elbow
300# extra heavy black malleable iron 90° elbows create a 90-degree change in direction between two male-threaded pipe ends, pipe nipples, valves, or compatible fittings of the same nominal size. Female NPT connections on both openings make these fittings suitable for demanding commercial, industrial, mechanical, fire-protection, maintenance, and repair applications.
