Nitrous Express 15910 Bottle Transfer Kit w/Stand Control Valve

BOTTLE TRANSFER KIT (COMPLETE W/STAND, CONTROL VALVE, & LINES) Nitrous Express bottle transfer kits are designed to allow you to refill your nitrous bottle without the use of a compressed air source. They are able to do this by creating a pressure differential between the two bottles, caused by simply cooling the receiving bottle. Nitrous Express bottle transfer kits include a stand, lines, and a control valve.
