works well
this is fine and cheaper than the brand name from the distributor. don't throw away the thin plastic valve? between the product and the unit. the trick is not to tighten the screws too much. leakage is prevented by the o ring, not by tightening the screws. the only point of the screws is to keep the o ring from popping out. the plastic is tender, and if you crack it, your product will be useless.
