• Read and understand all instructions before attempting to install any Victaulic piping products.
• These products must be used only on pipe that is prepared to Victaulic Advanced Groove System (AGS) specifications using Victaulic
AGS (RW) roll sets. DO NOT attempt to assemble these products on pipe that is prepared with original-type grooving roll sets.
• Depressurize and drain the piping system before attempting to install, remove, or adjust any Victaulic piping products.
• Wear safety glasses, hardhat, and foot protection during installation.
Failure to follow these instructions could result in serious personal injury, improper product installation, and/or property damage.
The information contained in this instruction sheet must be referenced to ensure proper installation of Style W07 AGS Rigid Couplings and Style
W77 AGS Flexible Couplings. Style W07 and Style W77 AGS Couplings require pipe that is prepared with a grooving technology called the Victaulic
Advanced Groove System (AGS). Victaulic AGS (RW) roll sets are required to produce grooves in accordance with this technology. Refer to the instructions in this sheet for complete grooving dimensions and assembly information.
PIPE END VISUAL INSPECTION – ALL SIZES
1.
Pipe ends shall be visually inspected in accordance with the requirements listed below.
PIPE PREPARATION – ALL SIZES

DETAIL A
2.
The front edge of the pipe end shall be uniform with no concave/ convex surface features (refer to the drawing above). These features will cause improper grooving roll tracking, resulting in difficult coupling assembly.
3.
If pipe cut-off is required, Victaulic recommends the use of a mechanically-guided pipe cutting tool for proper pipe end preparation. Free-hand pipe end cutting is not acceptable.
"S" Max.
1. Prior to grooving, the weld seams must be ground flush to the pipe surface (inside diameter and outside diameter). Grind the weld seam from the pipe end to a distance of 6 inches/152 mm back from the pipe end. This area must be smooth and free from indentations, projections, and roll marks to ensure a leak-tight seal.
1a.
Groove the pipe in accordance with the Victaulic AGS grooving specifications listed on the following page.
NOTE: PIPE MUST BE
ROLL GROOVED WITH VICTAULIC AGS (RW) ROLL SETS.
4.
Square cut the pipe ends (“S” dimension shown above) within
1/8 inch/3.2 mm.
1b. Clean the outside surface of the pipe, from the groove to the pipe end, to remove all oil, grease, loose paint, and dirt www.victaulic.com

NOTICE
• When grooving pipe for use with Style W07 or Style W77 Couplings, Victaulic roll grooving tools must be equipped with Victaulic AGS (RW) roll sets. Style W07 and Style W77
Couplings MUST NOT be installed on pipe that is prepared with original-type grooving roll sets.
• The Groove Width “B” dimension will be achieved with properly maintained Victaulic tools equipped with Victaulic AGS (RW) roll sets.
• It is critical to measure the Groove Diameter “C” dimension, along with the Gasket Seat “A” dimension and the Flare Diameter “F” dimension. These measurements must be within the specifications listed in the table below for proper joint performance.

‡ The Groove Width “B” dimension is listed for information only.
IMPORTANT – Grooving pipe to AGS specifications enlarges the pipe length by approximately 1/8 inch (0.125 inch/3.2 mm) for each groove. For a pipe length with an AGS groove at each end, the length will grow approximately 1/4 inch (0.250 inch/6.4 mm) total. Therefore, the cut length should be adjusted to accommodate this growth.
EXAMPLE: If you need a 24-inch/610-mm length of pipe that will contain an AGS groove at each end, cut the pipe to a length of 23 3/4 inches/603 mm to allow for this growth.

Check the gasket to make sure it is suitable for the intended service. The color code identifies the gasket grade. Apply a thin coat of Victaulic lubricant or silicone lubricant to the gasket lips and exterior.
5.
Apply a thin coat of Victaulic lubricant or silicone lubricant to the bolt threads.
3.
Position the gasket over the pipe end. make sure the gasket does not overhang the pipe end.
6.
Install the housings over the gasket. make sure the housings’ keys engage the grooves completely on both pipes. Support the segments while preparing to install the bolts and nuts.
6a.
Install the bolts, and thread the nuts finger-tight onto the bolts.
NOTE: make sure the oval necks of the bolts seat properly in the bolt holes.
4.
Align and bring the two pipe ends together. Slide the gasket into position, and center it between the grooves in each pipe.

Tighten the nuts evenly by alternating sides. make sure the housings’ keys engage the grooves completely. Continue to tighten the nuts evenly until metal-to-metal bolt pad contact AND the specified torque value are achieved. Refer to the “Required
Assembly Torques” table on this page. NOTE: Both conditions of metal-to-metal bolt pad contact AND the specified torque value are required for proper coupling assembly.
NOTE: It is important to tighten the nuts evenly by alternating sides to prevent gasket pinching. deep well sockets are recommended for proper installation due to the longer bolt lengths associated with these products. deep well sockets provide the full nut engagement that is necessary during tightening.
