Optimising your reg.

I did it to my RAW reg washers.

Does this help eliminate regulator creep?

What type of lube, silicone grease?

Interesting thanks, a before and after chronograph string would be awesome.

it makes a more constant spread , as for creep I found my regulators need new orings and to be cleaned and lubed , SO the creep is a leak by the hi pressure chamber to the low pressure chamber if it creeps up , if it creeps down it is usually a valve or seat or pin oring leaking ,

I use either pure divers silicone grease or oring lube is fine also super-lube is fine a tube will last many years , I stock orings and lube for all my guns . Also if you have a oring which doesnt hold try polshine things up with fine sand paper or polish and a drill or dremal or a lathe , if you chamfer and take away any sharp edges and polish where things move or an oring seals it can have alot better performance if you spend time with it .

I have tested this with identical regulators like huma or edgun and taipans and before and after it makes a huge difference ,

Good post to bring attention to some factors that affect regulator consistency.

I too like to deburr the Bellevilles when I'm setting up a regulator. I'm usually altering several things at once so I don't have a good sense of how much this individual thing helps. Given the compressive forces involved, I suspect it's not much but it's a simple thing to do and I don't want it muddying the waters.

As was mentioned, this step does not influence regulator creep in a meaningful way. Neither does lubrication of the O-rings, though they each may contribute something to the overall consistency of the setpoint. Creep is dictated primarily by imperfections in the sealing surfaces of the valve seat. Smooth and polish these surfaces out to 2000 grit or so, and/or carefully burnish the faces together with a mild abrasive and you will reduce creep to a level that is of no consequence.

Regarding lubrication, I recommend a hybrid lubricant like Superlube 21030 (grease) or oil (51004). The Bellevilles are not exposed to high pressure air so there is no reason to be concerned about detonation with a hydrocarbon lube, and pure silicone is a very poor lubricant for metal-on-metal interfaces, but it's hard to avoid cross-contamination with the O-rings on either end of the piston so I think Superlube strikes a good balance of these considerations.

very good idea. i once seen EARNEST FRom FX doing the same ,,,will give it a shot ,thanks HYNZIE 4Ss

Thanks guys. I have much to learn.
