Nitrous Outlet Backflow Prevention Valve Adapter

6061 Billet Aluminum Construction 1.125-12UNF Male to Female Four 1/4" NPT Check Ports Multiple Check Valve Positions Bottle Backflow Prevention Adapter Includes Four 1/4" NPT Plugs The Nitrous Outlet Backflow Prevention Valve Adapter is designed to add a safe and effective backflow prevention solution to nitrous bottle systems. This adapter threads directly into the nitrous bottle using a 1.125-12UNF male thread, while the bottle valve threads into the 1.125-12UNF female side, positioning the adapter between the bottle and valve. Machined from lightweight 6061 billet aluminum, the adapter features four 1/4" NPT check valve ports on the side of the body. These ports allow multiple installation positions for the Nitrous Outlet check valve, making it easy to achieve proper clearance and fitment depending on bottle orientation and system layout. When used with the Nitrous Outlet Bottle Check Valve, this adapter allows pressure from the fill line to force nitrous into the bottle while preventing nitrous from escaping when the fill system is not pressurized. This design provides a clean, reliable solution for a pressurized feed into the nitrous bottle.
