Brief tutorial video demonstrates how embedded O-Ring technology enables a standard stainless-steel fastener to become a high-pressure self-sealing fastener, that will seal up to 20,000psi (internal/external) against gas/liquid seepage. This particular “dry” one-step method is compared to other methods, including “wet” sealant/adhesive methods using a two-step procedure, which also exposes workers to harsh vapors and environmental disposal issues.
