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....
