NOTE 1: Due to the number of customers who order the wrong size valve seals and want to make a return, our policy is: Valve seals are Not Refundable. If you want to take a chance, that's fine but if you order these, they're yours to keep and cannot be returned for a refund. It's always best to check your guide sizes before ordering valve seals.
