Supreme (Danner) ASP14565 Diaphragm Replacement Kit for AP-100 Aquarium Air Pump

Perfect fit. Sure nice that you can buy a repair kit every few years rather than a new $300 unit.

Fixed our pump. Vs throwing it away great a company that actually makes a rebuild kit

Pump repair kit had everything needed however the replacement seal that came with the kit was too small, not suitable. Had to improvise. Otherwise great repair kit saving significant $$ vs buying new pump.

Broken Air Pump. Relaced Diaphram and washers

As advertised. A little expensive
