These all-brass shutoff valves and accompanying gaskets seem reasonably well made and we have not experienced any leaks. The valve was initially a bit stiff to operate, but it loosened up with a bit of use. We gave the valve stem a shot of spray lube to ease movement and reduce corrosion (in a non-drinking water application).More often than not, brass garden hose fittings like these are made in China or India, and the casting quality can be pretty bad. These castings appear good and they are finished fairly well, with no sharp edges or obvious casting defects (e.g., pinholes, shrinkage defects, mold defects, etc.).We think this is a very good value, as (at the time of this review) you get four valves for $16, or $4 each. We will post an update if we have any issues with the valves in service as time goes on.
