Tech Tip:
How Much and Where to Use Lubricant

Some people very sparingly lubricate the SPG swivel O-rings, but you should know that SPG and hose assemblies from our suppliers are never lubricated. If you do choose lube the SPG swivel o-rings, take care not to be so generous that lube might migrate up into the Bourdon tube mechanism and cause your SPG to become inaccurate.

Some people also sparingly lubricate the threads of valves before they are installed in the cylinder neck. Do NOT lubricate the neck O-ring itself, and do not lubricate the valve/regulator seal O-ring or DIN threads.

Most lubricant is used with dynamic seals in regulators and other equipment with moving parts. As a general rule, the O-rings used with static seals in SCUBA applications should not be lubricated at all. The lubricant just causes contamination to stick to the surface of the O-ring and results in more problems with a static seal than any dubious benefit the lubricant might provide.
