Argon back-purge device for TIG pipe welding. Threads straight onto any standard 5/8-18 argon hose — no adapters, no bushings, no O-rings to dry out and leak. The 20-micron sintered bronze element turns your argon into a soft 360° cloud instead of a jet, so nothing drags atmosphere back into the root. Machined hex brass, brite-dip finished. Small enough to ride in your pocket, tough enough to still be there in five years. Thirty seconds from bag to purging. Part number OU812. Patent pending.
