Well, now I am more confused. I made the trip to RS and bought the Lube Gel but after reading Chris's post I am unsure how to proceed. The lights are new and I would not want to damage them. <HR></BLOCKQUOTE>
If your TEC 40 is what you're wanting to lube, you won't damage it with the synthetic lube. Actually, you don't need, or want, any lube on the threads. The O ring is the only thing that should be lubed, and that should be done very lightly. If we knew the makeup of the O rings, and whether they can deteriorate with the use of petroleum distillates, we'd know whether synthetic lubes are even necessary.
Just a film of lube is all you want. Anything more will work itself off the O ring and solidify, along with attracting contaminates and create greater seizure problems. I've found that no matter what is used on TEC 20s and 40s, some of them seize within a few hours of use and you have to use both hands to get it started turning freely again. Others never develop that problem. I don't know why the identical products behave differently. It's something different in the individual O rings.
