Victaulic VicFlex I-VICFLEX Field Installation Handbook page 138

• A thin coat of a compatible lubricant shall be used to help prevent the gasket
from pinching, rolling, or tearing during reassembly.
• DO NOT use excessive lubricant on the gasket sealing lips and exterior.
Failure to use a compatible lubricant may cause gasket damage, resulting in joint
leakage and property damage.
7. Apply a thin coat of a compatible lubricant, such as Victaulic
compatible lubricant, to the gasket sealing lips and exterior. Silicone grease may be
used (silicone spray is not a compatible lubricant). It is normal for the gasket to have a
hazy white appearance after it has been in service.

CAUTION
8. Place the lubricated gasket onto the
inlet end of the flexible hose, then place
the Style 108 Coupling housings over the
gasket. Verify that the gasket is seated
fully in the gasket pocket of each housing
and that the housings' keys engage with
the spacer.
9. Install the linkage onto the housings, as
shown to the left.
10. Install the bolt, and thread a nut
onto the bolt. NOTE: Verify that the oval
neck of the bolt seats properly in the bolt
hole. DO NOT tighten the nut completely.
The bolt pads need to be set at a gap for
reinstallation of the coupling. The nut shall
be flush with the top of the bolt to provide
the proper gap.
11. Follow all steps on pages 133 – 134.
