In this case, the use of flexible type connectors (i.e.,
braided steel, elastomeric arch, etc.) are recommended
to attenuate vibration and prevent stress at the
waterbox connections.
All flange-to-flange assembly screws must be provided
by the installer. Hex head screw sizes and number
required are included in the tables in
Installation," p.
30. The four draw-bolts needed for the
16 in. (406.4 mm) Style 741 (150 psig [1034.2 kPaG])
adapters are provided. The Style 741 (150 psig
[1034.2 kPaG]) flange adapter requires a smooth, hard
surface for a good seal.
Connection to other type flange faces (i.e., raised,
serrated, rubber, etc.) requires the use of a flange
washer between the faces. Refer to the flange adapter
manufacturer's guidelines for specific information.
The flange-adapter gasket must be placed with the
color-coded lip on the pipe and the other lip facing the
mating flange.

"Victaulic Gasket
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 the following figure 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 hex head screw through the
mating holes of the Victaulic® flange to secure the
flange firmly in the groove.
6. Tighten fasteners alternately and equally until
housing screw pads are firmly together (metal-to-
metal); refer to
"Screw-Tightening Sequence for
Water Piping Connections," p.
excessively tighten fasteners.
N N o o t t e e : : Uneven tightening may cause the gasket to
pinch.
