O-ring Installation (Replacement)

Care must be taken when installing O-rings over threads dur-
ing replacement or installation. O-rings could become nicked
or torn. A damaged O-ring could lead to leakage problems.
1. Inspect O-ring for tears or nicks. If any are found replace
O-ring.
2. Ensure proper O-ring to be installed. Many O-rings look
the same but are of different material, different hard-
ness, or are slightly different diameters or widths.
3. Use a thread protector when replacing O-rings on fit-
tings.
