Title: Marauder tank overfill???
Post by: grimlama on November 16, 2011, 12:38:07 PM
Got a quick question for you guys with more experience than me.  I know that when they build these things they build a little safety margin on the tanks pressure maximum...I hope...A couple of times, I've fille my marauder and just barely, maybe a needle width gone over pressure...did not realize it when filling, but saw it later...eyes lie to me sometimes...

Question is do you guys know how much it would take to push these things too far.  Not gonna try, just curious.  I've read of shooters filling to 3200 psi on some guns and best I could tell, they hadn't been modified...

Just guessing, but I don't think my fills have even hit 3100 psi, but my accidental overfills got me to wondering...

You are fine.... I have filled mine to 3200 psi multiple times! Of course my gun is personally tuned for 28-32 fpe depending on pellet. The worst that would happen to you is valve lock, and all you would have to do is shoot it till it was back in its operating psi. range.

People have filled their Marauder to 4,500psi.!!! on "accident" and nothing has happened, so just use common sense and you will be okay.

The safety margin is really high, but like you, I dont push my luck.

Not sure what pressure the rifles are tested to but the tanks are tested to 5/3 working pressure. I would think that rifles would be to the same standard. I would never try to fill to that kind of pressure but things do happen.

Filled My Marauder to 4500psi by mistake. Gun is from the first month of manifacture. I called Crosman they Put Me through to thier designer. He had me shoot it down to 2500psi, Fill it back up to 3k, then dryfire it down to 1k, finally fill it back to 3k. End result working fine. Thanks to Crosman, A great Company.....Franky
  PS Degasser wouldn't thread in to empty overfill,had to grind 3/32 of point off Degasser to get thread to start

it's probably not a safe practice. so i won't recommend it. but i fill mine to 3300 and 3400 a lot. those gauges aren't exact by any means. i'm sure the safety margin will allow a little overfill. worst case scenario is something would leak or maybe even let go. my gauge is close to what my regulator says.
you should wear your seat belt and not speed either. ;D

i would assume crosman as a means for legal protection put some kind of a fail safe in the system. maybe the seal for the transfer port will let go before the air tube reachs its burst pressure..

the only real way to find out is to buy a mrod..lol.. a long section of hose and be behind some kind of protect with the tank and slowly start filling her up untill something some where finally gives out

im sure crosman has done that, and if there was some kind of myth about it id suggest it myth busters and watch them blow a few mrods up

you'll be fine at 3100 psi Lamar. depending on how it's tuned it could maybe valve lock, but not very likely. won't necessarily help to over fill it. i would check it for accuracy and chrony it from 3100 vs 3000 vs 2900 etc. and see what you get. ;D just my .02 if it shoots good and you like the curve then roll with it. ;D

Crosman tested tubes to 11,000. A Guy on a Canadian Forum Tested a Disco Tube to His Machine's Max.10K Nothing No streaching Nothing,Case Closed,
A Nitrogen 6K Tank won't hurt tube, maby F-up Valve or Guage but No LAWYER Trouble for Crasman.....Franky

Get the mrod degasser tool its like 15 bucks and is good to have on hand incase of a over fill you can degass some of tubes pressure back down to 3000psi...

Hey guys...again, I appreciate all the responses.  It's nice to know that these things have been tested to waaaaaayyyy beyond the max recommended pressure.  Was mostly just curious since I pushed past that point a couple of times, then got to thinking (which usually gets me in trouble)...lol

Good hunting and shooting all of ya!
