Victaulic fittings for AWWA size pipe are supplied with rigid radius grooves in accordance with ANSI/AWWA C-606. Fittings conform to ANSI A21.10/AWWA C-110 for center-to-end dimensions and AWWA C-153 or ANSI A21.10/AWWA C-110 for wall thickness. While most requirements are specified black or non-coated, fittings can be supplied with an alkyd-phenolic primer, or bituminous coating. Coal tar epoxy and other coatings are also available. The standard black asphalt coating used on our cement lined AWWA size fittings is NSF 61 Listed. Cast surfaces will be provided with surface equivalent to SSPC-SP6 prior to coating unless specified otherwise. Fittings are available with flanged ends wherever grooved ends are shown. Linings include cement/mortar Type 2 (standard) and others. Fittings can readily be prepared for glass lining by others. Fittings are rated for working pressures to 350 psi/2400 kPa (ductile iron) in 3 - 12 in/80 - 300 mm sizes and to 250 psi/1725 kPa (gray iron) in sizes 3 - 12 in/ 80 - 300 mm, and to 250 psi/1725 kPa (ductile iron), or 150 psi/1035 kPa (gray iron) for 14 in/350 mm and larger. Victaulic fittings shown have an end-to-end dimension tolerance of +/-1/8 in in all sizes and styles.
