Corken One Year Warranty

CORKEN, INC. warrants that its products will be free from defects in material and workmanship for a period of one 
year from date of installation, provided that the warranty shall not extend beyond twenty-four (24) months from the date 
of shipment from CORKEN. If a warranty dispute occurs, the DISTRIBUTOR may be required to provide CORKEN 
with proof of date of sale. The minimum requirement would be a copy of the DISTRIBUTOR’S invoice to the customer.

CORKEN products which fail within the warrant period due to defects in material or workmanship will be repaired 
or replaced at CORKEN’s option, when returned, freight prepaid to CORKEN, INC., 9201 North I-35 Service Road, 
Oklahoma City, OK. 73131.

Parts subject to wear or abuse, such as mechanical seals, blades, piston rings, valves and packing, and other parts 
showing signs of abuse, neglect or failure to be properly maintained are not covered by this limited warranty. Also, 
equipment, parts and accessories not manufactured by CORKEN but furnished with CORKEN products are not 
covered by this limited warranty and the purchaser must look to the original manufacturer’s warranty, if any. This limited 
warranty is void if the CORKEN product has been altered or repaired without the consent of CORKEN.

All implied warranties, including any implied warranty of merchantability or fitness for a particular purpose, are 
expressly negated to the extent permitted by law and shall in no event extend beyond the expressed warrantee period.

CORKEN DISCLAIMS ANY LIABILITY FOR CONSEQUENTIAL DAMAGES DUE TO BREACH OF ANY WRITTEN OR 
IMPLIED WARRANTY ON CORKEN PRODUCTS. Transfer of toxic, dangerous, flammable or explosive substances
