RTV Solution For Any Leaky Co2 Airgun

(1/2) > >>

hallwoo:
So, I got the Crosman  Peacemaker 44 22 Cal on Ebay auction on last bid of $63  last 5 seconds of auction

everything works , shoots with great power  on 22 cal pellets, .177 4.5mm pellets and buckshot of 2 BBs  per chamber

get only a 22  caliber   revolver pellet gun  so U can shoot any airgun ammo  in your arsenal 

but it leaks with only 24 shots  per co2 bulb  and loses all the gas within the hour  after installing a new co2 bulb

so, I decide to replace original co2 seal, but the retaining nut is frozen to valve body and the valve won't disassemble  with normal hand tools
I'm stuck with a unserviceable valve body and parts are NLA ( no longer available )

so, only thing I can do is build-up a new co2 seal on the old seal  worn crater area 
first layer of RTV was 1/4 inch thick on side of  co2 bulb  let  it set for ~ 2 hours

slowly rotate co2 bulb  back and forth CW and CCW until semi cured  1st layer releases co2 bulb with no rtv on bulb  tip  but still wet

then apply another thick 1/4 inch layer  and repeat above procedure

the new RTV co2 seal gets 48 shots  per co2  bulb now and seems to hold the gas indefintely

not perfect, but now I have a Peacemaker that shoots all airgun ammo from the hip with authority  at arcade  gallery range   and not a desktop paper weight

a 3800 psi pcp airgun only gets 30 shots on a charge
the standard 12 gram CO2 cartridge  is 7,000 psi 

the RTV is Pro Seal brand from the 99 Cent store for $1.49
Harbor Freight Tools has the larger 3 ounce size for around $5.49

U can apply this trick for any  LEAKY co2 gun and don't have to worry about disassembling it 
just have the patience to do it

Back_Roads:
 Try a .35 cal. big bore that gets 10 shots from a 3000 psi charge ;)

yes, after I get over shooting from the hip arcade gallery range

too much work lugging all that PCP gear to Spenceville Open Range  90 miles away from Bay Area
