Overview
Felt hub gasket for the HydraMaster RX-20 rotary extractor. HydraMaster part number 000-057-047, listed in the parts list as Gasket, Felt Hub.
The felt gasket seals the rotating hub. As the felt compresses and wears it starts to leak air, and the first symptom is usually lost vacuum at the heads rather than anything visible at the hub itself.

Frequently asked questions
How many do I need?
One per machine. Unlike the vacuum head gasket, which takes five, the hub seal is a single item.
How do I know it has gone?
Lost vacuum at the heads with nothing visible at the hub. The felt compresses and wears gradually, so it leaks well before it looks worn out.
Should I replace it when I service the hub?
Yes. It is a low-cost item and the hub has to come apart to reach it, so replacing it while you are in there saves a second strip-down.
