3/8M Boiler Safety / Security Valve

The 1.8 bar rating was exactly what I needed to match my machine's spec, and the brass threads seated perfectly without any PTFE tape fuss. Took me ten minutes to swap out the old one and now the pressure holds steady through every shot, no more hissing around the boiler.

Installed this on my old espresso machine and it fits the 3/8M thread perfectly—no leaks at all. The 1.8 bar rating gives me peace of mind that the boiler won't overpressurize. Exactly what I needed.

The 1.8 bar rating matches my machine's spec exactly, so I didn't have to second-guess the install. It threads on smoothly and holds pressure without any weeping around the seat, which is all I really needed.
