Our patented CAD2 manufacturing technique allows Flexcon to properly size the diaphragm in a full range of sizes from 14 to 119 gallons. Every tank undergoes a seam-weld test, high pressure test and is subjected to our famous helium test. Before leaving the factory, a final air charge check ensures each tank arrives at the job site with the correct precharge. Flexcon stands behind every Online tank with a five-year warranty. Just what you would expect from Flexcon: quality and performance, guaranteed!
