Fast, Simple and Safe Vacuum Devices for Leak Testing

Fast, Simple and Safe Vacuum Devices for Leak Testing

Simple to Operate: The air ejector has no moving parts and no lubrication is necessary. After applying leak detection fluid along the seam, simply place the vacuum device over the area to be detected and open the air valve.

Rugged Yet Lightweight: Our shockproof Vacuum Devices are built with lightweight acrylic which can be heat formed for special applications. The tough rubber gasket is designed to provide a maximum seal.

Fast, Safe Evacuation: Air ejection on standard models is less than 30 seconds. Our ejector is explosion proof and uses no electricity. Your compressed air supply (40-90 psi) will ensure safe, economical operation.
