Grooved Coupling Dimensions, Flexible couplings are designed to accommodate more angular movement and axial displacement for Victaulic plain end couplings. All fittings supplied with grooves or shoulders for fast installation. FLUID coupling provides better rigid connections for valves, fire mains, . ASTM F1548 and ANSI/AWWA C606. Intended for use nly in grooved piping systems. Used for grooved mechanical coup ings conforming to ASTM F1476. Zurn Wilkins Couplings and Fittings High Quality Fire Protection Products From the Brand You Trust Now you can get a full line of grooved fittings and couplings from Zurn Wilkins, the brand you already Specification Grooved Fittings FLUID Style 311 Rigid Grooved Coupling features moderate pressure ratings with lighter weights. Fitting pressure ratings are equivalent to the pressure ratings of the coupling used to install them. When connecting wafer or lug type butterfly valves directly to Victaulic The front edge of the pipe end shall be uniform with no concave/convex surface features that will cause improper grooving roll tracking and result in difficulties during coupling assembly.
