Magnesium Sealing

Vacuum impregnation sealing and pressure testing services

Magnesium wheels are typically porous – an issue when it comes to getting a high quality paint finish on the wheels and if you’re wanting to use tubeless tyres.

Magnesium is a porous material that can be troublesome if it is not adequately sealed. If porous, the wheels will quickly bubble and flake once painted and when fitted with tubeless tyres the porosity can lead to tyre deflation – something that can easily be put down to a slow puncture.

As standard:

  • Permanent seal against porosity
  • All sealed parts are issued with an Ultraseal certificate
  • All castings are handled with care and hand-washed by skilled, experienced operators
  • All parts are sealed using Ultraseal’s proven, best-in-class porosity sealant
