PROBLEM

Certain (3/4") XT-5 reusable stem assemblies-collet and hose assemblies need to be removed from dealer parts stock. Reusable stem assemblies-collet with a new design are available. The new design stem assemblies-collet have improved sealing capabilities for better hose retention. The new design is a direct replacement for the former design with the same part number.

A visual difference between the former and new design is the length of the stem. The stem has been lengthened in the new designs as shown in the following Illustrations.

Typical Examples of Former And New Stem Lengths

ACTION REQUIRED

Refer to the following charts. Remove all of the listed stem assemblies-collet and hose assemblies from dealer parts stock that were received before April 25, 2005.
