Vacuum Test Bell - Ground Lever - Internal Fillet Weld

Our vacuum seam test system consists of transparent sturdy test bells.

These are available in different shapes and sizes c/w a vacuum gauge.

A vacuum releif valve is integrated in one of the two handy grips on the side of the test bell.

This valve ensures a quick reduction of the vacuum.

If testing slightly eneven surfaces please ensure that tthe test bell is pressed harder onto the surfaces to build up a vacuum.

These test bells can be used on Hot Air Welded or Extrusion Welded Tanks/Fabrications as well as flooring and wall cladding to ensure a leak free joint.

Please see ralated products for our full range of shaped test bells.
