cooling system tester - with inflatable sealing bellows

Due to its unique sealing mechanism,
the tester can be used universally
for pressure testing of many cooling
systems. The unit is suitable for testing
cooling circuits, radiators, cylinder head
gaskets and water pumps.

• The inflatable sealing bellows enable testing
of a wide range of cooling systems:
- for radiator necks from 20 – 48 mm
- for radiators or expansion tanks
- fits on bayonet or screw caps.
• Universal applications for water cooled
engines
- for nearly all passenger cars
- for light commercial vehicles.
