Abstract
A ported fluid flow member has been developed in which one or more ports each is lined with a metal tube which has a portion projecting into the body member. The projecting portion may be crushed shut forming a metal-to-metal seal to seal off the corresponding port to flow. Methods have been invented for using the items with one or more of the lined ports.
