In the past Hypalon was the grip material of choice for many rods, but recent changes in the laws have made it impossible for Hypalon to be manufactured or imported to the USA. EPDM (ethylene propylene diene monomer) is a synthetic foam rubber material that has the same characteristics of hypalon , but is legal to make and use in the USA. We have it available in many lengths and bore sizes. So if you are looking for the hypalon type of performance look no further. We got you covered.
