Earl's Stat-O-Seals - 5/16" I.D. - (2 Pack)

The Stat-O-Seal is very simply the best sealing washer available. It consists of a synthetic rubber "O" ring mechanically locked to the I. D. of an aluminum washer. When tightened the "O" ring is compressed, forcing the sealing surfaces around the bolt shank. They will form a positive seal over a temperature range of -85? to +450? F. They provide the advantages of an "O" ring type seal without the necessity of machining "O" ring grooves into the part. In any application where you are now using a copper or aluminum sealing washer, the Stat-O-Seal will do a better job.

Earl's Performance Products was founded by Earl Fouts in 1955 in Lawndale, California. The mission was to supply high-quality military aircraft surplus plumbing components directly to the racing industry from a small retail outlet. As the military surplus market dried up, Earl recognized the need for continuity of supply for the racing market and pioneered the Earl's range of hoses and fittings that are still used today. In doing so he created the racing aftermarket plumbing industry.
