An insulative and resilient spacer member to be mounted between a heated manifold and a cooled clamp plate in an injection molding system. The spacer member has a plurality of V-shaped concentric rings. It has a uniform cross section with a number of web portions extending diagonally between alternate forward and rearward ridge portions. The outer surfaces of the alternate ridge portions are aligned to provide forward and rearward sides of the spacer member which extend parallel a predetermined distance apart. Some of the outer surfaces have an inwardly extending insulative circular groove. The spacer member is formed of steel to have a predetermined combination of strength, resilience and reduced thermal conductivity.
