Seal Kits for Paxton Superchargers

Paxton High-Speed Seal Set for Novi 1000, 2000

Background: The Novi 100 and 2000 models use radial seals on the impeller shaft. The stock seals are prone to weeping oil because of the lack of radial pressure on the PTFE lip. A slight spring load is necessary as superchargers apply negative pressure to the lip on over-run, causing the lip to lift (and leak).

The 928 Motorsports Twin-Lip Seal: Our impeller shaft seals are custom-made with PTFE-Coated Viton (higher temps and better chemical resistance than nitrile) they have the low friction of the all-PTFE seals at high speed, but the resilience of Viton to make up for small amounts of shaft wear (another thing that a standard PTFE seal cannot do). Further, they have a very light compression spring in them, less radial pressure than an industrial seal, but enough to fight the sealing lip lift that causes the oil weeping problem. And finally, our impeller shaft seals have two lips - the sealing lip pointed inward and a dirt wiper lip pointed outward. These seals have been tested at shaft speeds up to 150,000 rpm without failure.

This Kit Includes: One of our special twin-lip high-speed PTFE coated Viton seals for your impeller shaft, and one larger single lip high temp Viton seal for your input shaft. Enough to reseal one Paxton supercharger.

Paxton High-Speed Seal Set for Novi 1200, 1500, 2200

Background: Many Vortech® owners report problems with weeping seals. An impeller seal that leaks allows motor oil into the intake of the motor, where it lowers the octane of the air/fuel mixture and contributes to detonation.

Our Premium Face Seal: This is a direct replacement for the factory face seal, with an upgrade. The OEM seal has a limited range, and has a tendency to crack when over-heated. Our replacement has an extended range and is made from the finest materials for longer life. Customers have been very pleased with the performance of this seal.

The Input Shaft Seal: The input shaft of your Vortech® is the shaft that the pulley is mounted on. It turns much slower than the impeller shaft, and the sealing of it is much simpler. Our input-shaft seal is automotive-grade nitrile seal providing good durability and a long service life.

This Kit Includes: One of our custom Face Seals especially made for this application, and one larger single lip high temp nitrile seal for your input shaft. Enough to reseal one Paxton Supercharger.
