What is it on your regulator that you think needs lubrication and why?

What gas or fluid are you using the regulator for?

lube

I have just always wanted to make the screw on my torch regulator easeier to adjust. I take it apart and clean it but it sees the elements probably more than it should, I have always wanted to spray it with good ole wd 40 but have always been told not to

regulator lube

never use a petroleum based grease on regulators, exposed to pure oxygen wd40 or similar will ignite. There are products available for this purpose, one that I am aware of is FLUORLUBE. you can check out the website at www.gabepro.com/pdf/flgrea.pdf
usually a special order item for most distributors.
best of luck, and remember no petroleum products on regulators. BW

Hand adjusting screws on regulators are made to operate for years with no lubrication. I have seen some recent examples with plastic thread inserts and others have threads with loose tolerance as they only see low loads unlike grade 8 bolts. If your having problems with adjusting screws due to weather exposure then your gages are also in bad shape. Gages are not practical to repair only practical to replace. Can prevent such problems by storing out of weather and shielding them from rain when in use. I have seen more problems with valves on gas bottles exposed to salt spray and plastic coated canvas covers even help prevent salt spray problems.

Krytox is another O2 compatable lubricant brand. Problem with lubricant on exposed screw threads is it gets dirt impregnated. Apply then wipe off excess with paper towel.

This may sound silly, but ChapStick actually works.

I believe that most brands of chapstick do contain some petroleum (hydrocarbon) based ingredients. Although it may be a remote chance, if the regulator seat were to fail and expose the chapstick to pure O2 at pressure it could ignite, I realize that you could probably go three lifetimes without this happening, but if it were to happen I wouldn't want to be there! As always safety first.

Simple fact is the outside of O2 regulator isn't O2 clean. Still keep the outside free of hydrocarbons.

One diving ship I was attached to charged O2 tanks from LOX truck. We had to scrub the whole pier before chargeing O2 from LOX. Catch tray of clean gravel was below connection of charging hose to LOX truck. Fire Truck was on pier and fire team suited and ready on ship while charging from LOX. Royal pain but charged all ships O2 banks in hours getting them hot to touch. Would take muchlonger to charge from O2 tube truck using our corblin transfer pump. This ship was ASR21 a twin hull saturation diving ship with 2 saturation diving systems.

Just wondering... What about the powdered graphite lube?
