Return Policy on Seal Kits
Seal kits ship in a sealed clear bag. Do not open the bag until you have torn down your cylinder and can physically compare the seals. Remove the old seals from your cylinder and hold them next to the new seals in the bag. If the inside and outside diameters appear to match, you have the correct kit. We cannot accept returns on opened or used seal kits. Call 866-902-6060 before opening the bag if you have any doubt.
