Component: O-ring Only SAE Plugs
Product: Manifold
Case Number: 1040
Vibration caused plugs to back out.
Use Description
Old-style, O-ring only SAE plugs were used in manifolds of tree cutters. There is a high degree of vibration present during the operation of the equipment. This causes the plugs to back out and leak. The leaking fluid is an appearance problem on the equipment and could also cause equipment failure, possible soil contamination with accompanying clean up and EPA ramifications.
-04 through -20 Zero-Leak Gold plugs were installed in the new equipment and used as replacements for leaking plugs in the field.
No leaks have been reported wherever Zero-Leak Gold plugs were installed.
