The use of a SILICONE based grease only, is fine for the o-rings inside the regulator of an HPA tank (just enough to make them 'wet' looking). Use nothing on the fill side of things.
The danger is when a flammable (hydrocarbon based) lubricant is subjected to compression/heat inside an HPA tank ... think diesel engine ... not the output end of things.
Dave G I tinker, therefore I'm broke!
Further, now that I've found the MCB BST ... I've recently sold my house and moved under the bridge down the road ... but I've got lots of markers.
I have no life, I'm just a dad in constant flux between baby naps and 8yr old tantrums.
