MAGUIRE NOVATEC VL Series Instruction Manual page 15

This ring provides the vacuum seal between the motor lid, the filter and the loader body.
The ring must be smooth, clean and intact to provide a suitable seal for vacuum sealing.
Replace the filter if the seal is not in perfect shape.
Once cleaning/inspection is complete, the filter may be reinstalled by
placing it on the flat rim of the loader body (cloth DOWN and coarse
screen UP) and placing the motor lid down upon it and centering the filter
between the two. Replace the clamp and tighten. With newly installed
filters, the clamp may need to be adjusted to provide a vacuum-tight and
mechanically firm seal.
