Each Humphrey Products Pneumatic valve features the classic Humphrey diaphragm-poppet principle and Buna-N seals. Even with the strength of the materials the rings and seals are made of they do have a lifetime that is shorter than the metal material the valves are made from. Humphrey wants you to be able to have a short down time without having to completely replace the valve. That is why they offer Seal Repair Kits. These are available for any Quick Exhaust, 125, 250, or 501 series valves. Each kit comes with a replacement diaphragm and “O” Ring. Below are the item numbers for some of our most requested seal repair kits.
