Sealing Method

Unlike twin ferrule fittings that are made up with rotational geometry, coned band threaded connections are made up to a specific torque, installer must use a calibrated torque wrench.

NOTE

Medium and high-pressure connections are made up to different torques.

See tables:

Imagine a clock face around the nut, mark the nut at the 6 o’clock position

Assembly and Makeup of Connection

  1. Lubricate all contact areas (cone, collar where it contacts the gland nut & gland nut threads) with thread lubricant. Place gland down tubing, turn down the collar on tubing until one to two threads are exposed between collar and cone.
  2. Insert tubing in the connection, push gland into thread and tighten “fingertight”.
  3. Tighten to specified torque figure (see chart) using a calibrated torque wrench. Remember to hold the fitting body steady when torqueing the gland, this can be done using an additional wrench.
