DUROMATIC®/DUROTHERM® 壓力鍋閥門鎖緊螺帽

Finally found a replacement for that tiny valve lock-nut that kept slipping; this one fits perfectly and feels much more solid. My pressure cooker is sealing like new again.

It's a small part, but it fits the pressure cooker lid threads exactly as needed. Made in Switzerland, so the quality is definitely there and the stainless steel finish matches the original.

The lock-nut threads matched perfectly on my old pressure cooker, so no more wobbling during use. It feels solidly machined, though I wish it came with a small washer for extra seal security.
