4. Tighten the connection until the torque limitation has been reached,
which is indicated by a clicking sound.
5. Check whether the connection leaks. If leakage exists, follow the
steps further down.
Resolving Leakage with Viper Fittings with Torque Toothing
1. Remove the capillary.
2. Clean the capillary ends carefully by using a lint-free tissue wetted
with isopropanol.
3. Reinstall the capillary.
4. If the connection continues to leak, install a new Viper capillary.
To loosen a connection, use this side of the installation tool.

Connecting Viper Fittings with Knurls
To connect Viper capillaries with knurls, follow these steps:
NOTICE
• Tighten or loosen Viper capillaries only with your fingers. Do not use
tools other than the knurl that comes with the capillary.
• To avoid damage to the capillary or connection, tighten and loosen
the Viper capillaries
only when the system pressure is down to zero.
