To whom it may concern:
This letter is issued to provide notification of a documentation defect concerning QualTech NP Generation 3 Quick Disconnect Connectors (Gen 3 QDC). Specifically, there is a discrepancy concerning o-ring replacement between the 1/2 Inch Gen 3 QDC Qualification Report (EGS-TR-23009-14, through Revision B) and the Instructions for Installation (EGS-TR-23066-04, Revision Original), the 3/4 Inch Gen 3 QDC Qualification Report (EGS-TR-23067-01, Revision A) and the 1-1/2 Inch Gen 3 QDC Qualification Report (EGS-TR-23068-01, Revision A).
Section 5.0 of the 1/2 Inch Qualification Report (EGS-TR-23009-14, through Revision B) states in part that 'whenever the connector is disconnected after one week or more installed service, the used o-ring must be discarded and a new o-ring installed prior to reconnection.' Contrary to this requirement, Section 9.0 of the Instructions for Installation (EGS-TR-23066-04, Revision Original) states in part that, 'whenever the QDC is disconnected after one week or more installed service, it is recommended that the o-ring be discarded and a new o-ring installed prior to reconnection. This action, while not mandatory, will maintain the o-ring seal in a superior condition' and Section 6.0 of both the 3/4 Inch Qualification Report (EGS-TR-23067-01, Revision A) and 1-1/2 Inch Qualification Report (EGS-TR-23068-01, Revision A) states in part that, 'whenever the connector is disconnected after one week or more, it is recommended that the used o-ring be discarded and a new o-ring installed prior to reconnection.'
To prevent confusion and inconsistency between the 1/2 Inch Qualification Report (EGS-TR-23009-14), the 3/4 Inch Qualification Report (EGS-TR-23067-01), the 1-1/2 Inch Qualification Report (EGS-TR-23068-01) and the Instructions for Installation (EGS-TR-23066-04), the documents have been revised to require that the o-ring must be discarded and a new o-ring installed prior to reconnection. The new revision level of each document is as follows:
- EGS-TR-23067-01, Revision B - 3/4 Inch Qualification Report
- EGS-TR-23068-01, Revision B - 1-1/2 Inch Qualification Report
- EGS-TR-23066-04, Revision A - Instructions for Installation
The revised Qualification Reports and the Instructions for Installation have been or will be distributed to all customers who have received 1/2 Inch, 3/4 Inch, and/or 1-1/2 Inch Gen 3 QDC connectors.
Should any Gen 3 QDC connectors be currently installed in service, it is required that a determination be made as to whether or not the connector has been disconnected after one week of installed service and if the o-ring was replaced. If the o-ring was replaced, no further action is required. If the connector was disconnected and the o-ring was not replaced, the o-ring must be discarded and a new o-ring installed.
QualTech NP will provide replacement o-rings, free of charge, to customers who identify replacement o-rings are required for Gen 3 QDC connectors that have been installed in service.
As a point of interest, please note that this notification does not apply to the original EGS QDC connectors (Gen 1 QDC). QualTech/EGS QDC connectors certified to Qualification Reports PEI-TR-880701-04, Revision A (1/2 Inch Gen 1 QDC), EGS-TR-913601-01. Revision B (3/4 Inch Gen 1 QDC) and/or EGS-TR-913602-01, Revision B (1-1/2 Inch Gen 1 QDC) are not impacted by this notification as these Qualification Reports require the o-ring be discarded and replaced if the connector is disconnected after one week of installed service.
