Core returns are "like for like" and may not exceed nozzle purchases. All returned shipments are to be freight prepaid. If the number of exchange nozzles exceed the number of nozzles ordered, the remainder will be held in a core bank to be applied against future orders. Cracked cores will not be accepted. Returned cores must be intact. Core returns must be received within 60 days. Otherwise credit will be applied against future shipment. RGA's are required on all returns.
