Key Details from the Packaging

• Model/Series Label: The printed text clearly displays VUB4, which corresponds to a pneumatic valve designation (commonly associated with compact mechanical, air-pilot, or solenoid-driven sub-base valves).
• Warning Notice: The bag features text in both Chinese and English: "NOTE: Make sure the tube connection by pulling it when it is put-in." This instructs the user to give the air tubing a slight tug after insertion to ensure that the internal push-to-connect fitting has fully gripped the line.
• Manufacturer Logo: The black stripe features a JW stylized logo, a manufacturer specializing in pneumatic elements, cylinders, and connection fittings.
• Production Info: Marked with production tracking details including LOT. 95 E and 19008 MADE IN CHINA.
