5Helpful Hints & FAQs
LOX Transfill Adapter Quick Disconnect Valve (QDV) Service Replacement
When replacing the posi‐lock QDV (PN 10679176) on a liquid oxygen (LOX) transfill adapter, there is aseal to avoid leaks inside of the threaded end. This seal can be discarded as the new QDV service
replacement (PN 20803813) comes with a replacement seal. The new QDV should be tightened to 40 ftlb. and the transfill adapter should be tested for leaks after installation.

Posi-lock QDV and seal.

Travel Power Adapter
Portable concentrator power supplies are rated for universal voltages but require various power cords
depending on the location. Using the Travel Power Adapter will keep you from having to carry different
cords for the country you are visiting.
