They are standard metric threads. Just locktite short metric screws in place then leak test. I have done this a few times. If you remove the nipples you will find that is how they are installed no o-rings or gaskets.

The threaded brass air fittings on the Ultra Precision Valves are 3mm x .5 pitch
They are not 5mm like stated above.

You can use a short 3mm cap screw or set screw to plug them off if you wish.
