Super Hi-Flo 15 and 20 lb Nitrous Bottle Valve with Siphon Tube and Black Gauge

NOS now offers Super Hi-Flo bottle valve assemblies with the siphon tube and nitrous pressure gauge already installed, a great way to upgrade to the highest-flowing valve and tube NOS has to offer. Key valve features include a 1/8 inch NPT gauge port, a 1/4 inch NPT accessory port, large internal and outlet ports and an O-ring seal. The 3/8 inch I.D. screw-on siphon tube is made from 6061 aluminum and can be used as an upgrade for an older compression-fitting tube. Each assembly includes a 1-1/2 inch nitrous gauge, blue or black face, with easy-to-see color graduations and a white pointer. The gauges have a stainless steel case with brass internals.

Important: this product runs on nitrous oxide (N2 PI), a gas we do not supply and which is currently difficult to obtain. It is your responsibility to find a local supplier of gas for professionals. NOS bottles do not comply with CE standards (they do not carry the PI mark): only CE-approved bottles may be used. European manufacturers offer bottles approved to contain this gas; please check the applicable standards and verify the manufacturer's origin and compliance before purchasing. NOS fittings are not metric (AN / NPT threads depending on the part numbe PI): plan for the adapters needed for your installation. Please comply with the regulations in force in your country.
