WARNING
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.
A
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.
4.
Square cut the pipe ends (“S” dimension shown above) within
1/8
inch/3.2 mm.
PIPE PREPARATION – ALL SIZES

Pipe End and an AGS Groove
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.
1b.
Clean the outside surface of the pipe, from the groove to the pipe
end, to remove all oil, grease, loose paint, and dirt
