Review on Trident Deluxe Scuba Diving O-Ring Kit: Save-A-Dive for Tank Valves, Hoses, Regulators, Cameras, and more by Michael Tegan

This version of the kit is a very good set of o-rings for those diving in straight air. There are many options for o-ring kits and for beginners, be careful as you cannot use standard nitrox rubber o-rings, you must use viton o-rings. If you don't have scuba gear in your bag, get some! It's only a matter of time before you find out during a dive that the o-ring has broken or fallen out. It can ruin your whole day if you don't have spare parts.
