BottleBoss

BottleBoss – Because “Righty Tighty” Gets Complicated at 3 A.M.

Made by First Responders for First Responders.

The BottleBoss is the last oxygen wrench you’ll ever lose — because it’s not a wrench at all. It’s a knob-shaped lifesaver built to replace that tiny, always-missing O₂ key with something you can actually grab (even half asleep on a 3 a.m. call).

Precision 3D-printed and field-tested, the BottleBoss fits standard oxygen bottle stems with a snug, glove-friendly grip. Whether you’re cracking a tank open in the dark or closing one after a chaotic call, it gives you the leverage you need — no fumbling, no frustration, and no “where’s the key” panic.

And for those of us who occasionally mix up “on” and “off” after a long shift — don’t worry. The BottleBoss doesn’t judge. (But the oxygen bottle might.)

Features:

• Fits standard D & E size oxygen cylinder valves.

• Large, easy-grip knob design — usable with gloves or one hand.

• Available with or without a built-in key ring for customizable carry options.

• Designed, tested, and trusted by real first responders.

BottleBoss — For when you can’t remember if it’s “on,” or you’re just out of oxygen.
