45-degree elbow

A threaded 45-degree elbow redirects a pipe run through a defined, gentler angle than a 90-degree elbow. Its identity establishes 45-degree routing and threaded connection, but not male or female end arrangement, equal or reducing sizes, or thread form. It may be considered for an oblique route or a gradual offset in a piping layout. Selection should coordinate angle and installation envelope, both connection sizes and arrangements, sealing method, clearance to rotate the fitting during assembly, piping loads, and maintenance access with the project specification.
