I am in need of several replacement parts to keep my Dre Integra VSO2 machines running. Our previous supplier has been bought out and the new staff have been excessively slow and generally unhelpful. Does anyone have any alternative channels I might explore? Specifically I need
-O-Rings and gaskets
-Pop-off valves
-Pop-off valve indicator tape
-One-way diaphragms
-Diaphragm covers
-Pressure gauges
Thank you!
