INFERNO has STANDARDIZED valves and fittings for pressures up to 25,000 PSI, leading the way to greater savings for you. How? . . . By letting ONE volve take the place of three. Up to now, changing from one size tubing to another meant changing valves and fittings completely. Now, Inferno offers a complete change from 1/8", 3/16" to 1/4" O.D. tubing with the help of a small ferrule. (See Illustration) Inferno also offers other valves and fittings for tubing up to 1/2" O.D. Write for Bulletin NO. 10
