Specially built for inflating all bicycle tires and tubes, on all the different sizes and types of bike wheels, Park's Shop Inflator is a great shop-grade upgrade for your air compressor setup. For quick and easy inflating it has an ergonomic body for a sure grip, a 2-finger handle to control the air, and best of all, a small rotating head that's easy to fit between spokes, and that works on Schrader and Presta valves. Plus, you get an oversize, reinforced pressure gauge that reads from 0–220 psi (0–15 bars) and a pressure-release button for getting the psi exactly right. This fine inflator is built durably of quality materials throughout for everyday use in your shop and is rebuildable! It comes with a coupler plug compatible with most air hose quick-connect couplers. And it will accept any 1/4-inch National Pipe Thread fitting if you don't use a coupler.
