Product Description

Deep Umbrella Seals, POLY ACRYLIC


Package of 16 seals.

Note- Will not fit 90's 318/360 Magnum engines


We offer several different types of valve seals for small and big block Chrysler engines.

Chrysler used several different types of seals starting in the 60's to the late 80's.

This type of seal was used in the sixties. Both seals are the same depth and size. The same seal is used on both intake and exhaust.

Purchase these seals of you want 16 of the same seals as pictures above.

If your engine has the deep umbrella seals only on the intake with a shorter one on the exhaust, check our other listings for those.

Chrysler also used an all rubber positive seal on the intake with the shallow umbrella on the exhaust. If your engine has this type, we carry them also but only in a separate listing. To locate all the different seals for Chrysler, enter "Chrysler umbrella seals" in the search engine towards the top of the page and they should all come up in the search.

We carry all three kits.

Note- Applications with aftermarket dual springs might not accept umbrella seals. Check the sizes to verify fitment.
