Professional Applications
This mini coupling is engineered for demanding pneumatic environments including:
Workshop Air Tools • Automated Machinery • Control Panels • Instrumentation Lines • Robotics & Actuators • Pneumatic Cylinders • Vacuum Systems • Medical & Laboratory Equipment • Packaging Machinery • Automotive Service
Installation & Usage Guidelines
Tube Preparation
Cut tubing squarely with a sharp tube cutter (not scissors). Ensure the cut end is clean, burr-free, and fully round. Chamfer the outer edge slightly to ease insertion and protect the O-ring seal.
Connection Procedure
Push the prepared tube firmly into the coupling until it bottoms out against the internal stop. You should feel positive resistance followed by the collet gripping the tube. Gently tug to confirm secure engagement before pressurizing.
Disconnection Method
Depressurize the system completely. Press the release collar toward the fitting body while simultaneously pulling the tube outward. Do not force—if resistance is felt, ensure the collar is fully depressed and the line is at zero pressure.
