+ Must be smooth and free of deep pits or swells.
** Groove must be uniform depth for entire pipe circumference. Groove must conform to "C" diameter shown.
* Ovality, or out-of-roundness, must lie within specified tolerances.
# Min. standard wall thickness that should be grooved. Tolerances are to conform to ANSI/AWWA C151/A21.51.
For 18-36" (450 - 950 mm) ductile iron Class 53 pipe may be used. Contact Victaulic for details.

Victaulic groove specifications for cast pipe (gray and ductile) conform to requirements of ANSI/AWWA standard C-606.
For cast pipe, the groove is cut with a radius ("R" dimension) at the comers of the groove base to reduce stress concentration. Grooving dimensions are the same for any one pipe O.D. regardless of pipe class and pressure.
Standard preparation is with a rigid radius groove. Flexible radius groove dimensions may be used to provide expansion/contraction or angular movement allowance at the joint.
The outside surface of the pipe between the groove and pipe end must be smooth and free from deep pits or swells to provide a leak-tight seat for the Victaulic gasket. All rust, loose scale, oil, grease and dirt shall be removed. Peened surfaces may require corrective action to provide leak-tight gasket seal (refer to ANSI/AWWA C-606).
