An electrodeionization apparatus spacer comprising a rigid core comprising complementary mating first and second sections secured together with an unitary elastomeric material.

An electrodeionization apparatus spacer comprising a rigid core and a unitary elastomeric material, wherein a portion of the elastomeric material forms a seal disposed within the rigid core and wherein a portion of the elastomeric material encapsulates at least a portion of an outer surface of the rigid core.

An electrodeionization apparatus spacer comprising:

• a rigid core comprising an inlet port connected to a resin cavity through an inlet conduit and an outlet port connected to the resin cavity through an outlet conduit;
• and a unitary resilient material forming an inlet port seal around the inlet port, a resin cavity seal around the resin cavity, an outlet port seal around the outlet port, an inlet conduit seal around the inlet conduit, and an outlet conduit seal around the outlet conduit, and an outer seal disposed around a periphery of the rigid core, wherein the rigid core and the unitary resilient material is comprised of a thermoplastic polymer.
