Vacuum Seal Tester
The vacuum seal tester is used for testing the airtightness wherever EPDM washered fasteners have been installed. It will highlight any potential issues, such as water ingress, where a fastener has been incorrectly installed or damaged.

Description
Vacuum tester for testing the air tightness and weatherproofing of washered fasteners.
The vacuum tester kit contains:
- Main hand operated pump unit complete with calibrated vacuum gauge.
- Rubber adapter nozzles to suite 5, 19 and 29mm diameter washers
- Two lengths of flexible clear tubing
- Carry case.
Assembly / testing prior to use
- Select one of the 3 rubber adapter sealing nozzles which provide the best fitting over the head of the fastener to be tested. The nozzle must be able to sit squarely over the fastener head and provide 360° contact with the sheet surface during any test.
- Slide the metal retaining ring off the rubber neck. Push fit the base of the selected nozzle onto the connector on the applicator tool. Replace the metal retaining ring.
- Ensure the selector switch is on VACUUM.
- To test all connections are correct and that the vacuum gauge registers, push the rubber sealing nozzle onto any smooth flat non-porous surface and operate the pump handle twice. The vacuum gauge should show and hold a reading in the inner scale of about -50kPa. Either pulling away the sealing nozzle from the smooth surface, or twisting the selector switch to pressure will return the gauge to zero.
- If a reading was registered you are now ready to vacuum seal test the selected fastener.
Test method
- Ensure the HAND PUMP selector switch is on VACUUM.
- The area around the washer head must be wiped free from dust or dirt. This will ensure the sealing nozzle will fit flush to the sheet surface and prevents foreign bodies being sucked into the test equipment. Applying moisture to the sheet/nozzle will help in achieving a seal.
- Hold the applicator tool and position the sealing nozzle over the selected fastener head. Push firmly to achieve a seal and pump the handle.
- If after two full pumps, any tested fastener produces a reading above -50kPa, then the fastener can be deemed to be providing a watertight seal, even if the reading falls back to zero. Note a gradual fall in the vacuum back to -25kPa over 15/20 seconds also does not indicate water ingress.
- After 2 or 3 full pumps the gauge should register a reading more than -50kPa. If the vacuum falls to zero within 5 seconds it should be regarded as a failure. Note a gradual decline to zero in excess of 5 seconds would not indicate water ingress.
- In the event of rapid failure, that is no vacuum reading can be registered the test should be repeated. If a second failure occurs the fastener should be investigated, tightened or replaced as necessary and the test repeated.
Note: Note: It is important to note that this test equipment is creating and recording a vacuum. The vacuum test is a very stringent method of establishing the presence of air leaks and when applied to water, with its increased density and viscosity, a small air leak would not indicate a potential water leakage.
Features & Benefits
- Lightweight and simple to use
- Can apply a vacuum of up to 100kPa to the fastener seal
- Supplied with two bellows to suit bonded washers up to 19mm and 29mm respectively
- Supplied in durable carry case
