TODO GAS® 2 in. FNPT LPG Dry Disconnect Adapter w/ FKM Seal 3221-4437

TODO-GAS® couplings are used in a variety of LPG applications from heavy duty Autogas vehicle refueling to advanced vapor recovery systems. Easy to connect and disconnect, the TODO-GAS® 1” coupling offers single handed operation and ultra low release on disconnection. These features make TODO-GAS® couplings ideal for unsupervised fueling of vehicles, in fact, with a release of 0.15 cc per disconnection, fueling indoors is possible. The 1” TODO-GAS® coupling can easily handle flows up to 200 liters / minute (52 USG / min.) with minimal pressure drop. TODO-GAS® couplings are specifically designed for the safe transfer of LPG (typically Propane / Butane) in both liquid and vapor phases. The materials of construction and component design are specified to recognize the unique properties of LPG and terminal handling characteristics. Ultra low release on disconnection not only improves safety but also satisfies even the most stringent of environmental standards. Typical emission reduction is greater than 99% compared to existing thread based couplings. Just like their TODO-MATIC® stable mates, TODO-GAS® couplings remove the human error element from LPG transfer operations by ensuring that the valves are closed before disconnection is possible. Features Lowest emission volumes on disconnection ensures current and future environmental standards compliance No liquid release on disconnection removes the possibility of operator cold burns and reduces product loss to virtually zero Valves are closed and sealed before disconnection is permitted increasing safety by removing the possibility of human error Valves open and close automatically with no levers or handles to operate Rapid connection and disconnection saves time and simplifies operating procedures Highest quality design and duplex stainless steel construction conforms to all relevant standards including P.E.D. class II where applicable Integral swivel allows free coupling movement without imparting torque strain to the hose Downloads Installation Guide (PDF Download)
