Restricted-Area Sealing Means Or Restricted-Area Pack-Off

Pack-off or other device used to isolate an area at higher pressure from one at lower pressure. NOTE This device serves to limit pressure-induced loads on connectors or areas of a lower pressure rating. It may also be a seal that encloses a pressure-containment area smaller than the adjacent ring gasket or connector seal.
