1. An adjustable, multi-sectional, pressure-compensating fitting pad of desired shape and size, which comprisesa multi-sectional, shaped, flexible, protective enclosure having retained therein a predetermined volume of flowable, pressure-compensating fitting material, which, together, provide an adjustable, multi-sectional, pressure-compensating fitting pad,said multi-sectional enclosure being shaped and constructed to provide therein a reservoir section and at least one communicating primary fitting section, including interconnecting restrictable flow control passageway means, to allow confined fitting material in said primary fitting section to flow therein in response and conformance to continuously applied pressure exerted on that section of the fitting pad and the relief of such exerted, flow-producing pressure, and to provide a reservoir section from or to which at least some flowable fitting material may be selectively transferred, as desired, within the enclosure to or from said primary fitting section through said passageway means, said passageway means being positioned, shaped and constructed to be selectively opened, to provide for said transfer of fitting material from or to said reservoir or fitting sections, or closed, as desired, by separating or partitioning means,said closing of the flow control passageway means thereby selectively restricts or prevents the ingress or egress of flowable fitting material from one section to the other partitioned or separated section and maintains a desired or controlled volume of fitting material in said primary fitting section.
