Aluminum Stat-O-Seal Sealing Washers

Our special aluminum Stat-O-Seals are much more reliable than the more common steel version. Even if the rubber portion fails to make contact all around the port, the aluminum acts as a crush washer, providing a reliable metal-on-metal seal.

Each Stat-O-Seal has a Buna-N inner seal bonded to the center of the aluminum washer. The Buna-N rubber is resistant to water, oil, and petroleum fuels (not for use in brake systems). Use them to seal screws, bolts, or plumbing fittings. The rubber insert is molded to be slightly thicker than the washer, though not quite as thick as a standard rubber O-ring. Stat-O-Seals should not be used to replace O-rings on chamfered ports.

Sold individually.

Tip: Installing a 1/4" ID Stat-O-Seal under the pressure adjuster locknut on the FF1600 dry sump pump can help to minimize that pesky oil leak!

Preventing oil pan drips

By azhealey

from Tucson, AZ

Verified Buyer

Comments about Aluminum Stat-O-Seal Sealing Washers:

Tried most options to stop drips from oil pan bolts on 60 year of Jaguar. These washers appear to have done the trick. One note that was suggested by a local shop was to carefully 'thread' these over the bolts rather than push them on. Apparently the bolt threads occasionally cut into the rubber...so be careful.

Service and delivery comments:

fast and low cost delivery.

The best by far!

By Wrench on a bench

from Wilder, Vermont

Comments about Aluminum Stat-O-Seal Sealing Washers:

I first found these seals included in a Maserati V8 engine gasket set. Since then, I have used these in hundreds of applications. I keep my own stock in my tool box and swear by them. You can't go wrong.
