Stop Fitting

PISCO PNEUMATIC Pneumatics Fittings

Stop Fitting

Push-in fitting with built-in stop valve. The flow-shut mechanism will operate to stop the air flow when the tube is disconnected and allow air flow when the tube is connected. PBT is used for the main resin parts. PBT: A standard resin material that is ideal for general environments. Brass with electroless nickel plating is used for the main metal parts. The specified fluid medium is Air. Maximum operating pressure is 0.9MPa.

Product Overview

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.

Construction and Materials

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.

Configuration and Connections

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.

Operating Characteristics

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
