صمام مانع للفراغ 1/4 بوصة دبوس طويل

The 1/4-inch long pin fits perfectly into my espresso machine’s valve housing and stopped the pressure drop I was dealing with. It’s a simple part but it feels solid and well-made for the price.

I was worried about pressure fluctuations during brewing, but this valve fixed the issue immediately. The 1/4-inch pin fit snugly into my machine without any modification needed.

The pin length is exactly right for my machine—it seats firmly and I haven't had a single pressure drop during pulls since installing it. Took about two minutes to swap out, and the build feels solid enough to last.
