Victaulic Gasket Installation

1. Inspect supplied gasket to be certain it is suited for
intended service (code identifies gasket grade). Apply
a thin coat of silicone lubricant to gasket tips and
outside of gasket.
2. Install gasket, placing gasket over pipe end and making
sure gasket lip does not overhang pipe end. Refer to
Figure 18 for gasket configuration.

3. Align and bring two pipe ends together and slide
gasket into position centered between the grooves on
each pipe. No portion of the gasket should extend into
the groove on either pipe.
4. Open fully and place hinged Victaulic flange around
the grooved pipe end with the circular key section
locating into the groove.
5. Insert a standard bolt through the mating holes of the
Victaulic flange to secure the flange firmly in the
groove.
6. Tighten fasteners alternately and equally until housing
bolt pads are firmly together (metal to metal); refer to
"Bolt-Tightening Sequence for Water Piping
Connections, " p. 28. Do not excessively tighten
fasteners.
Note: Uneven tightening may cause gasket to pinch.
