Works as expected, not like those Milton valves that leak. The tank was pressurized to 60 psi and held for over 1 hour. So far I would recommend them. I like the metal valve cover that doubles as a tool for removing or tightening the internal valve stem. Overall good quality. Remember to use thread sealant or teflon tape of your choice. satisfied so far. Revain sends five stars. The update still works great. If they were up to 120psi, no problem. Hold the air well.
