Twelve-inch rubber splice is used to join two ends of ThermoPEX together. Includes band clamps. Fittings and crimp rings for joining the PEX lines are sold separately.

NOTE: Do NOT use 1330, 1331 or 1333 PEX Adapters with ThermoPEX Coupling Kits as the barb on these adapters is too short for underground splices. Use 5642 or 5643 Brass Clamp Fittings.
