quick question about ray's valve stems
 

I have a set of Volk wheels and they came in the box with the valve stems but they were not mounted on the wheels

the valve stem has a rubber washer on the bottom

so after inserting that through the wheel...there is a metal washer and two nuts

I would assume the the washer goes first then tighten the first nut and the second nut is basically a means of reassurance that they stay tight against the wheel?

I ask because two of my wheels seem to be leaking air

would it be necessary to apply locktite to these nuts or should hand tightening them be enough?

when I gave them to my tire/wheel guy to have tires mounted he said there were no issues

again these are official RAYS valve stems that came with the wheels

any advice...preferably from someone who has these valvestems

I have Volks on my car and a couple of others in the past and have never seen my installer use Loctite on the valve stems on any of them.
