TR-55 CGA-540 to CGA-540 Oxygen Transfiller Device
The TR-55 is the most economical way to fill your cylinder. One side has a CGA-540 nut & nipple with internal threads with an O-ring seal, while the other end is equipped with a large hand nut with bare nipple with internal threads. This allows you to slowly and safely bleed the line so the fittings can be easily removed from the cylinder. This transfiller is also available in a DIN-477 (Euro-norm) version. Length: 18 inches
