I had a stoke but i'm still shooting. Have trouble writing so be kind. I have a 22 avenger. About to install a new regulator. Do you lube a new regulator. If so, silicon oil, or Sta-Lube water resistant "Marine Grease". Never taken an avenger apart. Help much appreciated.
Air Venturi air-venturi-avenger regulator (new) Can it be lubed.
- Thread starter stroke
- Start date
Apply silicone grease or silicone oil to the O-rings.
Silicone provides no useful lubricating properties for metal-on-metal contact so if you want to lubricate the Belleville washers, use a conventional lubricant (30W oil, automatic transmission fluid, Super Duper Alien Spacecraft lube, etc.). The Bellevilles occupy the vented chamber at atmospheric pressure, therefore a hydrocarbon-based lube is okay.
That's the Cliff's Notes version but if you want to read over a prior thread on regulator maintenance and lubrication, the following one goes into more detail:

EDgun - Lelya 2.0 Rising Velocity Questions
Last squirrel season I began noticing that I was missing shots that I shouldn’t miss. I’d suspected that something was awry with my .25 Edgun Lelya 2.0 i suspected a valve or reg issue. Consequently, I shelved her and it’s probably been 8 months to a year since I shot this rifle. Yesterday I...

How do you get the Belleville washers and O rings out for servicing. Looks like you need to force them. Didn't want to without more info. Virgin at taking the gun apart. Trying to tract down a loss of power. Spent 4 months sending the gun back to Air Venturi multiple times. No joy! Both a .177 & .22 operated correctly for 6-9 months, then the loss of power.
I first measure efficiency with a chrono. Shooting well for 6-9 months. Now I get a 80-100 fps drop in power. Didn't notice any air leaks. Cleaned the barrel. Used to get 2nd zero at 60 yards, now its 45 yards. Replaced the reg with no service to the O rings because I didn't know to remove them.

I'm working also on the regulator problems on my Avenger in 25 caliber. I degassed the rifle then removed the regulator and the oring close to the tip was flat and was like a hard plastic and shattered when I tried to remove! Never seen anything like it but I guess 4350 psi plays hell on rubber. I took one as close as I could find out of my captain oring kit I got off eBay for the rifle and it's still too big but kind of works. It's been a slow leaker but you couldn't hear or feel where it was coming out so it was driving me crazy and the leak was this tiny oring causing all that trouble. Hope this helps!

This explanation may be more nerded out than you care for, but while the flattening is in fact the result of the high pressure, the hardening/brittleness is from the rapid heating effect of the refill cycle after each firing.

Thanks for that explanation. I've only had mine for three months so it going bad that quickly is a bummer. I've purchased a bag of 50 from the oring store for $1.00. that's a lifetime supply for this rifle!
