WEH® Quick Connector TW02

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.

Key Features:

• 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.
