Snoop's Take

The Captain O-Ring is a pack of ten replacement paintball fill nipple o-rings designed for HPA tanks, made from durable 90 durometer polyurethane. Users appreciate the durability of these o-rings, with comments like, "While I’m at it, I want to replace all of the o rings," highlighting the product's reliability. However, some users have reported issues with o-ring softness leading to splitting and leaking, as well as concerns about the size of color-coded o-rings. Overall, despite some criticisms, the Captain O-Ring is generally recommended for its durability and effectiveness in maintaining air tanks in working order.

That’s what I figured. But I’ve never blew o-rings on my cold water units, only when I started using the heated unit.
