Patent ID: 7503590

Claim:
A fluid line assembly, comprising: an outer fluid line; an inner fluid line; and wherein the inner and outer fluid lines each include a slip joint, at least one of the slip joints including a variable volume reservoir in communication with the interior of the corresponding fluid line, the reservoir at least partially defined by a first tube section, a second tube section having an axially extending portion and radially extending portion, and a radially extending piston connected to the first tube section for movement therewith, the at least one slip joint also including a resiliently compressible conductive member positioned between and in contact with the piston and the radially extending portion of the second tube section to create an electrical path therebetween, the resiliently compressible conductive member is divided into sections, wherein each section is separated from an adjacent section by a spacer member adapted to inhibit contact between the axially extending portion of the second tube section and the resiliently compressible conductive member.
