3/8インチ メス x 1/4インチ オス 真鍮継手

Threaded onto my espresso machine's portafilter without any wobble, and the brass feels solid enough to outlast the machine itself. The 3/8" female to 1/4" male step-down was exactly what I needed for the new pressure gauge, and it sealed tight on the first try.

This little adapter threaded together perfectly without any cross-threading, and the brass has a solid, heavy feel that gives me confidence it won't crack. Exactly what I needed for that awkward transition in my setup.

Used this to connect my water line to a fridge ice maker, and the 3/8" female to 1/4" male adapter fit perfectly without any leaks. The brass feels solid and well-machined, no burrs on the threads.
