The Tank O-Ring Holder is a must-have compact accessory for scuba divers. Designed as a durable and lightweight keychain shaped like a scuba tank, it combines functionality with style.
The tank’s top unscrews to reveal an O-ring hook and a hollow interior, perfect for storing spare tank valve O-rings. This convenient design ensures you always have extra O-rings ready when needed.
A stainless steel split ring on top allows easy attachment to a keychain or the zipper of a dive bag. Plus, the keychain comes pre-loaded with tank valve O-rings for added convenience.
