NGR Type-S O-Ring (Adjustment Screw Seal)



This is the O-Ring for the adjustment screw, it is a seal to prevent leaks from the adjustment screw.

It can wear out from people overtightening the nut on the adjustment screw, thus creating a boost leak. To prevent this, make sure to tighten the locknut on the adjustment screw with a 10mm socket by hand. DO NOT OVERTIGHTEN!

We decided to put this up for sale as customers tend to overtighten the locknut, which will cause the o-ring to break. We want to make sure customers can have this part available in case it is needed.
