I had a spare in my parts that came from Benjamin when I got the Kratos.
Where do I gets more? I see Amazon has disks for the YoungHen, 7mmx17 but I don’t know if they are the same(mine don’t measure 7mm).
I have the Kratos parts schematics that list a ‘seal’ in that area of the diagram, but they probably want 10 bucks or so to get it to me.
I would rather have a dozen or so if I knew where to buy them. I can order one for less than 7 bucks from UK, but the postage is over $20.
I will call Crosman Monday to see how much they are, if I can determine that what Crosman/Benjamin calls a ‘seal’ is really a burst disk.
Thanks in advance,

???? how did you pop a burst disk on your rifle?
-
I need some also, and probably need a new plug as well. My Akela is still leaking very slowly from the threads of the burst disk plug. I put a new burst dust in, but it's still leaking about 1 bubble per second. So, not fast, but still leaking. I was going to call Crosman on Monday also to get a few burst disks and a new plug. I'm hoping that will fix it. If not I may need a new block and air cylinder since I've not been able to get those two parts apart!

What was the air tank pressure when the disks burst?
I have been overfilling my Akela to 3200-3400 PSI to get a decent shot count and would like to know how much it can be overfilled.

Under warranty Crosman should ship those parts for free.

I had filled less than an hour before and used the auto shut off, it did not blow, it just started leaking at a rate I see when I open the degas vent. When finished I then reset it to 4500 psi to fill a tank. I suspected I may have had a slow leak earlier, but suspected I had just not filled it after using it last.
I will contact Crosman tomorrow if no one knows a cheaper source.
The disc that blew resembled a intact rivet on a pair of Levi’s with the nipple sticking up on the center, did not see a hole.
I fill my Kratos to 3625 routinely, it has a 3625 psi TalonTunes cf tank. It is sometimes regulated and is now. My Bighorn I fill to the same pressure, it is a rated to 3625 psi.
I think it was a faulty disc,

Blowing burst discs is usually a change of underwear moment. Hope yours wasn’t.

Frank,
Good thing it wasn’t a Big Bang, I was right next to it. It was just a leaking sound that quickly got louder, then slower as the pressure went down. Took 5 minutes or so to empty completely.

Bought 2 from Crosman, $7.00 each.

Ouch! I may try and find another source of supply!
-
I agree that $7 per seems to be a high price, but with luck 2 of them will be a lifetime supply!
I popped one about six or seven years ago (through my own stupidity) and then laid in a supply to have on hand, and none have popped since . . .
-
Paint ball shop should have those
-
I did burst a disc on one of my Storms once maybe 3-4 years ago,.....just made a replacement cutting the lid of a Benjamin pellets tin :)
-
Two spares come in the little parts bag. I measured 8.83mm (0.348") OD X 0.43mm (0.017") thick.
-
Those are just a tad larger than the burst disks used in the YH Compressor. Those measure 7*7*1mm / 0.28*0.28*0.04 inch thick. The may be too thick because they are probably rated at 5000 psi, but the diameter may be too small to seal on these rifles.
-
Looks like it is also on the Puncher Breaker, and is one of the more common leak points. Tightening of the set-screw to seal it. I didn't see a US sourced supply, just UK.
