Introduction
1.11 VTT O-rings
Various O-rings are utilized throughout the VTT Compressor to contain the refrigerant. Prior the
removal of any component utilizing an O-ring, the refrigerant must be properly recovered per
industry-standard procedures. Upon O-ring replacement, a leak test should be performed. The
following O-ring-specic steps are required when replacing any VTT O-ring:
1. Remove each O-ring to be installed from its package and inspect for defects such as blemishes,
abrasions, cuts, or punctures.
2. Slight stretching of the O-ring when it is rolled inside out will help to reveal some defects not
otherwise visible.
3. After inspection and prior to installation, lubricate the O-ring with a light coat of Super-O-Lube.
4. Avoid rolling or twisting the O-ring when maneuvering it into place.
5. Keep the position of the O-ring mold line constant.
NOTE
It is strongly suggested that anytime an O-ring is removed, that a new O-ring is used in its place.
