What Makes BarTite Unique?

BarTite sealing nuts employ proprietary PVC plastisol sealant, unlike ordinary molded or sheet rubber compounds which only create static seals. The plastisol is applied as a viscous material that adheres to the metal washer and thermally sets. The result, when compressed, is a sealant that flows in every direction to fill all gaps, creating a truly dynamic seal.
