preset blow burst disc

[fkinpaintball]

just pulled out my PMI 5000psi preset to use & found the burst disc on the low pressure side 1800psi gone (blown).. how can i find out if its creeping up. or are they some thing that goes now & again.....

is there! or where do i obtain an service kit??

you can get the burst discs from planet

not sure if this is right, but you could make a psi reader but getting a on/off and screwing in a gauge. they stick ur bottle in all the way and watch the gauge to see if it shoots up or what.

it probably just needs a clean out and a a service...dig out the instuctions and have a go if you are confident, if not ask someone who knows what they are doing.

asked just & said that there was no sevice kit available.. burst disks sell all the time.. cant put the gauge in as different thread..

how can u tell if the burst discs are gone?

i was turning on my air one day and it made a loud bang, then proceded to function properly, tank is holding around 1100psi. i havnt filled it since this..?

I can service these presets if needed.

I had my 1.8k disk blow on the way home from the last walk-on I went to. Stripped it down and there was a load of dirt of the piston o-rings

Gave it all a good clean up and re-grease and it's been fine (with a new disk in) ever since.

Always sems to be the same sort of thing with these (PMI) systems, my mates was losing pressure gradually and my other mate has had the same thing with the burst disk as me, I think I'll strip it a bit more often than usual to make sure it doesn't happen again

Must get myself a fill nipple cover though...

hrm

both my 7500psi and 1800psi appear to have holes through them

youve got the nut bit at the top, then under this youve got a cylinder secion wiht the PSI rating, its this bit thats got the hole. then it steps into a smaller cylinder and goes into the preset. both of them look identical....?

ps, im a bit of a noob

if your burst disc had burst you'd know all about it! loud bang and air leaking through the hole.
the burst disc is actually a copper disc designed to burst at a given pressure. it is held in with a grub screw with a hole in it. thats probably the hole you can see.
basically if your bottle holds air and it doesnt leak out as fast as you fill it your burst disc is fine.
