For External Tube & Hose Testing Pneumatic Actuation Vacuum to 35 bar
The WEH® TW02 is a pneumatically actuated quick connector designed for fast, tool-free connection to external tubes, hoses, and male threads. Built for high-cycle use in automated testing environments, the TW02 ensures reliable sealing under vacuum or pressure up to 35 bar, improving both efficiency and repeatability.
Pneumatic Automation: Perfect for inline testing systems and production environments.
External Sealing: Designed for external diameters from Ø 0.8 mm to 77.0 mm.
Elastic Front Seal: Conforms to rough, irregular, or out-of-round surfaces—ensuring leak-tight performance even with tolerance variations.
No Hand Tightening: Connection is achieved in seconds by applying pilot pressure—fast, secure, and repeatable.
Optimized for Automation: Ideal for pick & place applications, robotic systems, and leak testing benches.
Customizable: Twin connectors for closely spaced ports and urethane seals for high-wear applications available upon request.
Note: The TW02 does not retain the test piece—fixture support is required during testing.
