AquaMatic K524-RAN EPDM Diaphragm and Seals Kit 1070274
AquaMatic K524-RAN Diaphragm & Seals Kit (EPDM) – Part No: 1070274
The AquaMatic K524-RAN Diaphragm & Seals Kit (Part No: 1070274) is a genuine factory OEM seal replacement kit designed for the routine servicing and maintenance of AquaMatic K52 Series 1 ½" and 2" composite control valves.
This kit features 100% industrial-grade EPDM (Ethylene Propylene Diene Monomer) elastomers, making it the standard choice for reliable sealing in everyday water processing applications. Over extended operational cycles, pressure fluctuations, mineral scale, and exposure to common water conditioners will wear out internal seals. Replacing your seals with this factory-spec kit restores tight hydraulic isolation, prevents external weeping, stops internal fluid bypass, and ensures crisp valve cycling.
