How to successfully install a new seal

The following is a guide on how to install a new D400/C250 manhole cover seal correctly.

An outline for replacing seals can be found in the D400 Installation / C250 installation guides located in the product section of this site, however we will explain the process in more detail here.

The first step is to remove the damaged seal. This can be done by using pliers or similar tool in order to remove a section of the seal out of the cover.

Once a section has been released from the groove of the cover then the rest can be pulled out by hand. When inserting the new seal ensure that the orientation is correct.

See the following video on how to insert the seal into the cover.

 

Excess seal issues

An issue that can occur when installing a new seal is the appearance of excess seal as shown in the image above.

This is not due to the seal being too large but is instead due to the seal being pulled too tightly as it was being fitted.

By removing a portion of the seal from the grove on either side of this will slacken the seal. Then it can be refitted into the grove correctly.

The following video demonstrates how to solve this issue.

We hope this provides useful information on seal installation and replacement.
