This high-flow 150 psi fixed regulator is the first of a series of new regulators from Ultimate Air. The FX1500 features a built-in safety relief valve, a "never-lose" washer, and an automatic quick-disconnect coupler that allows for one-handed operation of the hose connector. This patented regulator features the latest in regulator technology and was specifically designed to withstand the punishing off-road environments that trail riders venture to. Ultimate Air is so confident in the quality and durability of its regulators that the company backs them up with a limited lifetime warranty.
