Grease/oil on hard plastic o-rings?

[Jonnydread]

I have two PPS guns whose bolts utilize hard plastic O-rings. Should I put oil or grease or anything on these? I’ve been running them dry and it seems fine, but it just occurred to me I’ve never thought to ask.

I was always told oil only and like most things in life... in moderation =)

Out of curiosity did you hear that from Palmer’s?

A friend of mine with an army of palmer markers gave me that advice. Here is the Lubrication section off the Blazer owner manual for direct advice from Craig:

LUBRICATION

A necessary part of proper maintenance!
If you want your paintgun to enjoy a long and trouble free life, proper lubrication is essential. There is a bottle of oil included with this gun; use it frequently but sparingly. Use only approved lubricants!! AIR TOOL oil or DOW 33.  Air Tool oil is provided with your gun and is available at Palmer's or your local Hardware or Tool Supply. Do not use spray-on lubricants or white Lithium grease. Most spray lubricants contain solvents (used to thin out the oil to make it sprayable) that can be harmful to seals. CO2 and Lithium grease combine to become something close to chewing gum. Only about 7 to 9 drops of oil are required to lubricate your paintgun completely. One drop of oil on each of the 0-rings of the bolt (3) (A light coating of petroleum jelly, aka Vaseline also works well on the bolt o-rings) Two or three drops to the hammer and mainspring (applied through the slot at the lower/left side of the gun) and two or three drops of oil into the pneumatic system will provide adequate lubrication for approximately two thousand shots/cycles. To lubricate the automation and firing systems internally, apply oil to the depression in the face of the tank valve or apply directly into the gas supply receiver. With oil in the tip of the tank or in the gas supply receiver; charge the gun up and fire/cycle it several times. Air moving through the gun while firing it, will distribute the oil to the internal components as needed. Any excess oil will pass through the gun and some excess oil will be deposited in the barrel, reducing accuracy if not removed. Internal lubrication of the Pneumatic system is only needed every 2000 to 3000 shots or after thorough cleaning. Remember, only 2 or 3 drops of oil at a time are all that is needed. A thorough cleaning and lubrication should be done after each day of use.

I always gave them a little oil, worked good for me.
Theoretically they can run dry, but I didn't.

Dry pumpin’s the worst.

I run my Blazer flat rings dry, and have had no issues...

If in doubt, call Palmers... A lot of the time Craig answers the phone..

Thanks all! And special shout out to Loophole for the copy/paste right on man

[Loophole]

My pleasure my friend! Copy pasta is the way =)

They used to say to use a little oil on em. I always use a little oil on my bolts, regardless.

I'm sure they work fine dry. Those delrin rings are pretty cool I'm a big fan.

I run them "dry" barring what little air tool oil I add to the ASA before each day of play that makes it to the bolt. Both my Blazer and my Pyre have their original bolt o-rings and they are both over 13 years old.
