Review on WYNNsky Switch Female Thread Fitting by Gabriel Salleh

I bought three of these - one two years ago and one recently. One is on the pressure gauge used to measure 60 psi and two on the propane gauge which only measures 15 inches of water, but in either case they shouldn't leak. All valves work perfectly. All valves I received were in good condition. Sealant pre-applied to male threads but not shown in photos. This pre-applied sealant worked very well. The ones I received interacted properly with pipe thread fittings - not so with another brand, lower cost than I tried!
