Water Piping
Grooved Pipe Coupling
A customer-supplied, standard
flexible grooved pipe coupling
™
(Victaulic
Style 77 or equivalent)
should be used to complete the
Victaulic connection for both 150 and
300 psig water boxes. See Figures 15
and 16 . When a flexible coupling
such as this is installed at the water
box connections (Figure 16 ), other
flexible piping connectors (i.e.,
braided-steel, elastomeric arch, etc.)
are usually not required to attenuate
vibration and/or prevent stress on
the connections.
Refer to the coupling manufacturer's
guidelines for specific information
concerning proper piping system
design and construction methods for
grooved water piping systems.
Note: Flexible coupling gaskets
require proper lubrication before
installation to provide a good seal.
Refer to the coupling manufacturer's
guidelines for proper lubricant type
and application.
