The “AITHRE® oxygen transfiller is the most economical way to fill your Aithre Oxygen Bottle. One side has a CGA-540 nut & nipple with an O-ring seal, while the other end is equipped with the AN-800-3 (3/8-24) fitting to fit your Aithre fill port. This allows you to connect the 540 end to your larger portable or supply cylinder while slowly transferring pressure to the Aithre tank. Hose bleeding is accomplished by ‘cracking’ the AN-800 nut. The Aithre transfiller features a standard 24 inch (61 cm) high-pressure braided stainless steel flex hose (other lengths are available on request).
