Items sold, but not manufactured by Samson (including materials, equipment, or components such as hoses, FRLs, electric motors, etc.) are subject to the warranty, if any, of the original manufacturer. Samson will provide purchaser with reasonable assistance in making any claim for breach of these warranties. However, if the original manufacturer denies such warranty claims, Samson has no additional liability.

All equipment determined by Samson to have defective materials or workmanship within the warranty period will be repaired or replaced at Samson’s discretion. This warranty specifically excludes soft parts and normal wear parts.
