Metalsub announce new range of technical lubricants for diving equipment


Metalsub are pleased to announce their new range of lubricants: silicone grease for equipment maintenance, and a white grease for pure oxygen applications.

Silicone Grease

Keep rubber, plastic and metal thoroughly lubricated with this 100% pure food-grade (but don’t eat it) silicone grease.

Rubber, metal and plastic parts can wear out and dry up when you’re not paying attention. So be sure to protect and condition your O-rings, valve systems and regulator components on all your dive gear with Silicone Grease. You’ll find lots of uses for this handy, long-lasting silicone lubricant that’s specially formulated to permeate rubber surfaces. Try it on underwater cameras, waterproof dive lights, pressure systems, pipe fittings—anything you want to protect against moisture and degradation.

Give your O-rings and other rubber, plastic and metal parts the attention they deserve. Use Silicone Grease by M Essentials to prevent cracking and drying—for a better seal and longer life.
