Sometimes we need to double-check to make sure things are safe, which is why Vanseal Corporation will double-check your seals before we package and ship them to you.

Did you check the house is locked?
Did you check the weather?
Did you check you have your wallet?
You double check a lot of things – just to be sure.

Vanseal pressure checks for seal leakage prior to packaging.

The Market Demands Quality

Failing to double-check crucial components can leave you open to legal action because they can create a potentially dangerous problem. Seal leakage is not acceptable no matter how low a manufacture’s defect rate may be. A PPM of 1 can be detrimental to business if that single part leaves a semi-truck stranded, a hydraulic motor out of service, or a shipment of goods behind schedule. Or worse, cause harm to person or property.

Ever aware of the issues that seal leakage can cause and its devastating effects, Vanseal recommends incorporating a Seal Pressure Test step, before the packaging process. Tested seals that pass our test are then stacked and sealed into container tubes for shipment.

How the Test Works

Pressure testing does not interfere or delay the production timeline. Pressure testing is a simple process and does not add any additional cost to the project.

  • The seal lip is pressurized with air
  • If the sensor detects any pressure decay – the system’s red indicator light will illuminate
  • Seals that fail the test are disposed of, and not included with the shipment

The pressure test also serves as a way to identify and eliminate seal design or production issues. A client approached Vanseal with a seal design flaw that had a 37 PPM instance of leak paths. After examining the previous manufacturing process, Vanseal added the Seal Pressure Test. This step significantly reduced warranty issues for the customer and saved a lot of costs associated with recalls.
