HPA Tanks

McMaster Carr, and they won't sell to Canada.... ARSIE here has an account with them, you can probably tag onto his next order, whenever that is....

Anyone want to trade some washers and shims for an emt?..

[SeanMP]

Out of shims- trying to find a decent supplier- the "paintball" businesses who have offered up HPA tanks/parts in the past have only been fiddling in the HPA world and they have proven to be generally unreliable suppliers for these sorts of small parts. Problem is, companies like Fastenal only seem to have one or two of the correct sizes, but only one or two thicknesses. Who the heck out there has a real selection/inventory of Belleville washers?

What is the ID-OD of these washers?
I could be mistaken but I don't think the shims in my reg are "Belleville" washers. I thought they were hardened ground shim washers with a coil spring. Did they make a change?

The Belleville washers are 5/16" ID x 5/8" OD x 0.032" thick.... They are used in all the Ninja regulators intended for 1000 psi and up, and there are also flat shims to fine tune them.... The regs with the coil spring are the "paintball" version.... They come at 850 psi and you can reduce that by removing flat shims (about 150 psi drop per thick shim).... The regs all share the same body, and you can convert the coil spring version to higher pressures by changing the spring for a Belleville stack.... The standard stack is )) () () () () (( .... Sometimes the end washers are thinner (0.022"), or there is only one on one end.... I have a chart giving approximate shimming for different pressures.... The shims go on the end nearest the air inlet (tank end) of the spring / belleville stack....

And the .022" option

Bob....
That's interesting info. My reg has the coil spring and I reduced the output from 2000 to 1500.

I hit my first "snag" during my project.... and I havent even started yet! I am a lil concerned about the tank washers and hoping Eric finds some before its time to air up. I have alot of work to do beforehand so that will help with the wait.

I believe so, they look exactly like the ones in both of my reg's.

Never heard of a Ninja reg with a coil spring that wasn't 850 psi or less.... Interesting for sure....

My ninja's are all coil spring, but interestingly enough some of the LP regs on paintball markers themselves use belleville washer types to reduce the 850psi down to under 200 psi.

Regarding the flat hardened shims.
Does anyone have exact ID OD measurements?

Would 3/8 ID work?
Are there any potential problems with having 1/32" clearance on the ID?

I'm asking because 3/8 ID 5/8 OD arbor shims can be found by the reams in any thickness desired.
