With the Blue Diamond Rebuild kits you can replace worn diaphragms without having to replace the entire pump.
As with all diaphragm operated air pumps there is eventual wear on the diaphragms so these kits enable you to extend the life of your air pump. Blue Diamond provide detailed instructions on how to replace these diaphragms once you have the rebuild kit.
Rebuild / Repair Kits fit Blue Diamond pumps. It is not recommended to use generic or other pump parts on Blue Diamond air pumps.
