INDUSTRY: Construction Equipment

COMPONENT: Cylinder - Hydraulic

PROBLEM:
It was determined that a low profile and less expensive
plug would better suit this particular application.

USE DESCRIPTION:
Plugs were being used in the cylinder.

SOLUTION:
An engineering change was made to incorporate the Zero-
Leak Gold Plugs into the product BOM.

RESULTS:
Zero-Leak Gold Plugs have become the "choice of the
future" because of their quality and performance.

POST SCRIPT:
The Zero-Leak Gold Plugs were recommended to an affiliated
company where they were accepted and installed. 62421
