When installing the nipple it is important that you do not overtighten the nipple into the port. The GA nipple is designed to allow for strut movement and if the nipple is tightened too deeply into the port the stut will bottom out and can't open properly to allow air flow, especially with flash fill operations. This will cause the o-ring to "roll" since it is the point of least resistence. Make sure the nipple is only tightened deep enough to seal and you're good to go.
