The Stop Fitting is a one-action push-in coupling designed to safely connect and disconnect air tubes while automatically stopping airflow when the tube is disconnected. Its integrated stop valve ensures that air flow is interrupted immediately upon disconnection, providing safety and preventing accidental leaks during maintenance or handling.
The main resin components are made from PBT (polybutylene terephthalate), a standard engineering plastic suitable for general environmental conditions. The metal parts, including the body and valve housing, are constructed from brass with electroless nickel plating to enhance corrosion resistance and durability. The sealing interface uses NBR (nitrile rubber), which provides reliable sealing under air pressure but has limited ozone resistance.
The Stop Fitting features a push-in connection mechanism that allows for quick and secure attachment or removal of tubes with one action. The coupling is designed as a single integrated component, combining the tube connection and stop valve function into one unit to simplify assembly and reduce the number of parts required in the system.
The Stop Fitting is rated for air flow operations under a maximum operating pressure of 0.9MPa and can handle vacuum conditions down to -100kPa. It operates within a temperature range of 0
