A Better Square-Drive Knob

Get a solid grip on that bottle with a Pro-Werks Bottle Knob. This lightweight, all-American solution features deep notches, and they match the rest of the Pro-Werks lineup of signature Easy Turn Fill Caps and aluminum knobs

Starting with American melt, aircraft-grade 6061-T6 aluminum; we precision machine each knob on one of our multi tasking MAZAK CNC machining centers, then finish them in your choice of anodized black or silver and our popular micro-polished aluminum finish.

Available in two different square drive sizes to accommodate valves found on most CO₂ bottles. For proper selection, we recommend that remove your original knob and measure the "square drive" of the bottle valve to confirm your size before ordering.
