Assemble the joint by inserting the grooved
end of the sprinkler piping into the opening of
the coupling. The grooved sprinkler piping shall
be inserted into the coupling until contact with
the center leg of the gasket occurs. A visual
check is required to verify that the coupling keys
align with the groove in the sprinkler piping and
engage with the spacer on the inlet end of the
flexible hose.
WARNING
• The nut shall be tightened until metal-to-metal c ontact occurs at the bolt pads,
as indicated in steps 5 and 6.
• DO NOT continue to tighten the nut after metal-to-metal bolt pad contact is
achieved.
Failure to follow instructions for tightening hardware could result in:
• Damage to the assembled joint (damaged or broken bolt pads or fractures to
housings)
• Bolt damage or fracture
• Joint leakage and property damage
• A negative impact on system integrity
• Personal injury or death
NOTICE
• During tightening, support the hose near the Style 108 Coupling to verify
that the inlet end of the Victaulic

are achieved.
If you suspect that any hardware has been over-tightened (as indicated
by a bend in the bolt, bulging of the nut at the bolt pad interface, or damage to the
bolt pad, etc.), the entire coupling assembly shall be replaced immediately.
