SMC quick-connect fitting.
[Features]
・ Stainless steel specifications that can be used in a corrosion resistant environment
・ SUS303 is used for the metal material part
・ It can be used in CRT lines that dislike copper ions, water cleaning of food equipment that is exposed to water or salt water, and in cleanrooms that dislike dust generation due to discoloration and rust of copper materials
[Applications]
・ Used for resizing quick-connect fitting
