Replacing the Door Gasket 

To avoid injuries, replace the gasket while the autoclave and autoclave door are cold. 

Removing the Old Door Gasket

Before we start the replacement process, make sure to remove the old door gasket following these instructions:

Start by opening the door of the autoclave and removing the old gasket from the groove.

Then clean the groove thoroughly with a plastic scraper and some plain water as needed. Make sure there is nothing left in the groove that will hinder the seal of the new door gasket.

Putting in the New Gasket

When you’ve cleaned out the groove thoroughly, then you need to lubricate it for the new seal. Manufacturer’s recommendation is to use silocone-based lubricants like Würth Silicone Lubricant or Dow Corning 111 when installing. Line the inside of both sides or walls of the gasket groove with a small amount of the lubricant. It can be sprayed in or brushed depending on what kind you use. Fully coat the inside of the groove, but be careful that you’re not putting in too much.

Caution: If insufficient lubricant is applied, replacing the gasket will be difficult. If excess lubricant is applied, the gasket will ‘spring’ out of the groove. 

Now it’s time to put in the new gasket. Remove it from it’s package and press it into the groove all the way around with your finger or other tool. You do this in one continuous motion for proper installment.

You must make sure that the gasket sits flush and evenly without waves, humps or cavities. These can lead to the door gasket not having a proper tight seal to the unit, making its own whole list of problems, so be thorough. The following drawing shows a proper representation of how the seal should sit inside of the groove:

Final Test 

Once your new gasket is installed, we recommend running a test cycle to make sure the seal works properly. Once the cycle is run and everything is working the way it should be, your autoclave and it’s new door gasket are ready for use!
