This section describes how to connect Viper™ capillaries. All Viper flow connections in the Vanquish system are designed to be finger-tight.

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.

  2. Tighten the connection by the knurl.

  3. TIP

    Note the slot in the knurl. You can easily remove the knurl from the capillaries through this slot if space is limited.

  4. Check whether the connection leaks. If leakage exists, follow the steps further down.

Resolving Leakage of Viper Fittings with Knurls

  1. Tighten the connection a little more.

  2. If leakage continues, remove the capillary.

  3. Clean the capillary ends carefully by using a lint-free tissue wetted with isopropanol.

  4. Reinstall the capillary.

  5. If the connection continues to leak, install a new Viper capillary.
