Vindicator Visual Safety Tank Valve Air Indicator

Vindicator Visual Safety Tank Valve Air Indicator comes from Vindicator, sold through our Amazon affiliate catalog rather than FGSS's own stock. Replaces the original valve handle with a colored-ring indicator. Red ring fully visible when off; green ring covers red when fully open. Sold in multiple models to fit specific valve brands (confirm compatibility before ordering). The color-ring system exists specifically so a buddy or instructor can glance at your tank and confirm the air is fully on, not just partially -- worth double-checking which of the numbered models actually matches your specific valve brand before ordering. Heads up: this listing checks out on Amazon, not through FGSS directly. We're an Amazon Associate, so a qualifying purchase here earns us a small commission -- it doesn't change your price.
