Frequently Asked Questions

Is Tribolube 71 safe for oxygen service?

Yes. Hollis lists Tribolube 71 as a synthetic, oxygen-compatible lubricant for oxygen-based diving systems. The manufacturer describes it as chemically inert, non-toxic and non-migrating, and safe for all materials used in scuba systems. It is the type of lube used where hydrocarbon-based greases would present an ignition risk, such as servicing regulators and valves intended for oxygen service.

Can I use it on rebreather o-rings as well as regulators?

Yes. Hollis states the lubricant is designed for maintaining o-rings on both rebreather (closed-circuit) and open-circuit gear, and that it is safe for all materials used in scuba systems. That covers o-rings and components on regulators, valves and rebreather assemblies. It is also suitable for equipment used in saltwater and freshwater diving.

How much lube is in the syringe, and what do I receive?

You receive one 2 oz / 57 g syringe of Tribolube 71, Hollis SKU 220.8131. The syringe format lets you apply controlled amounts directly onto o-rings and small parts. The 2 oz / 57 g syringe is the configuration Hollis publishes for this part number.

Does it stay stable in cold water or under high pressure?

Hollis states Tribolube 71 maintains performance under pressure and in low temperatures without degrading. Hollis also describes the formula as chemically inert, non-toxic and non-migrating.
