2. Slip the gland nut onto the tubing.
3. Apply Pure Goop to the threads on the tubing. Screw the collar onto the threaded end of
the tubing leaving 1-1/2 to 2-1/2 threads exposed on the tubing between the collar and the
coned tubing.
4. Apply Pure Goop to the male threads on the gland nut and insert the tubing into the
connection. Engage the gland nut and tighten finger tight.
5. Tighten the gland nut to the torque specifications in Table 2-8.
Proper piping supports and guides must be provided. End connections will not
support the tubing load alone.

Anti-Vibration Connections
The bending stresses resulting from excessive vibration or shock on the threaded area of the
tubing can cause premature failure at the back of the thread. When tubing will be subjected to
vibration, rotation and movement, anti-vibration connections must be used. The anti-vibration
collet gland transfers the stress to the unthreaded section of the tubing, and the gripping action of
the collet strengthens the entire assembly.
