Product Description

Umbrella Seals, Nylon w/ Viton Insert

3/8" Heavy Duty Full Size Umbrella Seals

Fitment: 3/8" stem BB Chevy, FE Ford, SB & BB Chryslers.

Purchase is for 16 Seals

 

When it comes to 3/8" umbrella seals, these are finest design ever offered.

The seals body is made from a high temperature resistant hard nylon material with a viton grommet/insert which seals between the nylon body and valve stem. The viton insert greatly improves its ease of installation. Unlike solid nylon seals where some oil still passes between the seal and stem, the viton insert seals completely in this area.

This type of seal will not harden and break apart like other umbrella materials. The nylon body is already hard as manufactured, it will not break apart or disintegrate like rubber seals do over time. They are much more tolerant with rubbing against springs/guides than soft rubber materials.

The best feature is the seals have a very long life and frequently can be re-used even after significant mileage.

This style seal was the final design before the OEM's were forced to go with positive seals to satisfy new emissions standards.

If you're going to run umbrella seals and want the very best there is to offer, look not further.
