SeaLife Silikonfett für SportDiver & Sea Dragon Lampen O-Ringe, mit O-Ring-Entfernungswerkzeug

The O-ring removal tool is a simple addition but makes taking the seals off my dive light incredibly easy without scratching anything. A tiny bit of this lube keeps the threads moving smoothly, and I've been using it for all my underwater gear. Feels like a necessity if you own a dive light.

I was a little skeptical about buying a separate lube, but this one is noticeably thinner than the generic stuff I'd been using—makes applying it to the O-rings way less messy. The removal tool is a nice bonus, too, since I always fumbled with a pick before.

The little removal tool is the hero here — I used to gouge O-rings with a tiny screwdriver, and this pops them off clean without a single nick. Silicone grease goes on thin and keeps the seals on my light supple between trips.
