Among the fittings currently available for use in water main work are options for both weldable and nonweldable applications, as well as for pipe with standard and nonstandard dimensions. The development of fittings for nonwelding situations, as well as for pipe with nonstandard internal and outside diameters, has been a primary factor in the growing use of the "on-stream" alternative when water main work is needed. Weldable fittings, caulk-joint fittings, and mechanically mounted fittings are described in detail.
