Quality distribution blocks are a necessity for today's multi-stage, high-power nitrous systems. NOS engineers have taken the tried-and-true showerhead design and turned it into a low-profile, user-friendly design. The parallel inlet/outlet layout allows a much more compact installation of the nitrous solenoid feed lines. The internal passages are profiled to maximize flow and minimize pressure drop across the block. For the best-flowing, most compact showerhead distribution blocks, look for the NOS logo.

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.
