BUSY-CORNER 166 Pieces Scuba O-Ring Kit Scuba Diving Rubber Orings, for Dive Hoses Ring Diving Dive Gear Equipment Scuba Tanks FKM90

I am a certified technician for servicing SCUBA gear and own a lot of gear. I go through a lot of o-rings. These o-rings are made from Fluorocarbon (FKM) so they are oxygen compatible. They are as good of quality as any other brand I've used and have not had any issues with them. Contains the common sizes needed for a standard SCUBA gear setup. The case is great for keeping them separated even during transport. They are a great value and worth their weight in gold if you are on a dive trip and need to replace an o-ring. Cheap insurance! Recommend them to all divers.

On my last dive trip I didn’t have a set with me and of course blew the o-ring on my transponder on the way out to the dive site. Of course it was a less common size and we couldn’t find a replacement on the boat. You won’t catch that happening again as this set has everything I need and will have it with my at all future dives. Love the selection and quality.

Must have in the Save-A-Dive kit. Nothing worse than missing a dive because an o-ring blew out at the wrong time. I also dive with a DIN regulator and that o-ring will disappear every once in a while.

Better to have when you need one than out on dive trip with blown O-ring. A good value for what you get. I've not used any of them yet, using from prior purchased set still.

Lots of o rings

Save a dive kit

Great

Has every size o ring you’ll need. Much cheaper than save a dive kits and will last you many years. At my job I simply can’t have an equipment failure. So easy any diver can benefit from having a set. Works with enriched air.

The o rings are old and hard, they aren’t pliable enough to use. They break.
