Earl's Stat-O-Seal - 0.5 in ID - Rubber O-Ring (Pair) Turnlock Fastener Insert Plate Keep your work bench cleanThe 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.
