launcher grenades leaks gas help

[scottasuse25]

hey iv got to gas grenades for my launcher and the valves keep leaking gas i fill them and u can hear the gas comin out. the other u can see the gas leaking out im not shore how to fix it i was thinking it was the o rings so i sprayed them with silicon spray that didnt work im thinking the cause could be the weather as the gas might freeze the valve keeping it open if anyone has any suggestions fire away please

thanks

check that the middle bit....

ok... let me try and be a bit more methodical.

There should be a piece of metal in the middle of where you stick the tip of the gas can to fill the grenade. Make sure this is not on a lean or anything like that..... It can cause them to leak.

We are planning a pistol and grenade maintenance evening some time in the next month, Bladerunner will be giving an in depth presentation on how to maintain grenades at that.

well I'd be in for that...

I'm forever breaking my pistolas

If you use a too powerful gas such as the propane from bunnings then the o-rings won't last long as I found out with my King Arms Grenades. Using the Green Gas canister propane which is a lower pressure seems to work for my madbull grenades. Yes it does cost more to use green gas on your grenades but at least you are not always looking for new orings.

The o ring I found which blows out first is the tiny one inside the fill valve. I went to DOTMAR near Addington raceway trying to find a replacement but they didn't have anything that small. The end result was I had to order new fill valves from UNCOMPANY instead.

i use green gas but that still does it. i think i need new rings not to shore i cant make them strait as buddy said they always move

[Bladerunner]

Sorry Manley that is not correct I have alway used the propain from Bunnings and have never had a problem . Orings only have a limited life in the 203 Shells due to the explosive nature of these things. These Shell need to be serviced on a regular basis. I am now in a position to obtain all the Orings and the ball bearings 3mm and 4mm including the tiny 1x1mm oring for inside the valve. As Nem has stated We are going to do a maintainence night and I will show you what to do and were to get what you need.

Just Sounds like your shells are due for a service. I can do this for you or come to the maintainence Night.
What Brand is your Shells.

Cheers

when is the maintenance night. ah i dont really know i got them from mouse

They are king arms shells dude. I always found that keeping them gased, using lots of silcone spary really helps with keeping them working but even then they can still be a real pain in the arse.

[scottasuse25]

haha yeah i know what u mean by pain in the arse iv drowned the o rings in silicon spray and there still not working lol

[Bladerunner]

If any of the orings have deformation or small dent or are out of shape they will leak and will need replacing. I can Sort that for you. Silicon Spray will make the oring swell then they will get damaged as you are trying push it into the hole that is now to small for the swelled oring. A dry powder form of silicon is recommended.

if u can sort me out with some new o rings that would help thanks blade
