I just got my tank in the mail and I love it!!! I just have a small problem, and it might be an error on my part. When I got the tank I replaced the Brass with the Aluminum bonnet, then decieded, because the Vice runs better on Low Pressure, to change the shims. There's my Problem, there are only 3 shims, 2 red and 1 thin silver. My question is this, was it shipped wrong, did I make a mistake, or do they only get shipped with 3 shims now? Any help would be great and if indeed I need 2 thin silver ones to have LP I'd love to get it some how.
This is a very common question that we get about the number of shims in a ninja reg. The red shims provide most of the pressure adjustment, the silver shims provide a very minor adjustment.
Because everything that is made has a tolerance each ninja reg will be slightly different. We test every ninja reg and will put in the silver shims to make sure that the output pressure is correct before it leaves here. Most of the regs will have 2 silver shims, some may only have 1 or some may have 3. This will ensure that every reg goes out at approximately 800 psi. When you adjust the ninja reg just remove or add the red shims as needed and leave the silver shims in the reg. If for some reason you want a lower pressure then 500, 650 or 800 then you can remove the silver shims.
In your case if you remove the 2 red shims and leave the 1 silver shim you will get approximately 500 psi output pressure. If you remove the silver shim this will lower the output pressure more.
Hope this helps and if you have any more questions just post on here.
Alright, so if I want low pressure I just need to use the one small thin silver shim?? Will it hurt the tank if I only use the 1 shim that was in the reg. Is it also a problem that I changed the brass to the aluminum bonnet, like you said, all the regs are tested, but this one is different now that I have the aluminum. So will there be any repercussions?
Thanks again Ray!!
