The WEH® TW18P is designed for automated vacuum, pressure, and function testing during production, offering safe and pressure-tight connections to male threads in seconds—without hand tightening or additional sealants. With a pressure range of vacuum up to 350 bar, it is ideal for integration into automated control systems in high-volume manufacturing environments.

Key Features:

• Pneumatic actuation (P) via external valve for use in fully automated, semi-automatic, or external manual systems

• Leak-tight connection without tools or thread sealants

• Time and cost savings on frequent testing cycles

• Clamping strength increases with pressure for added operator safety

• High-quality materials for long service life and reliability

• Ideal for automated production lines, robotics, and test benches

Technical Data:

• Max. Operating Pressure: Vacuum to 350 bar (5,000 psi)

• Pilot Pressure: 6 – 12 bar (90 – 175 psi) compressed air

• Temperature Range: +5°C to +80°C

• Leak Rate: 1 x 10⁻³ mbar x l/s
