I need a gasket for this Curtis CCA-1550 drain valve, where can I find the part number?
Per the manufacturer, replacement seals for these drain valves are no longer available. We do not recommend that they be overhauled. Replace the valve if it begins to leak.
Additionally, the valve is not recommended for halogenated hydrocarbons, nitro hydrocarbons, Phosphate ester hydraulic fluids, automotive brake fluids, ketone, ethers or alcohols. Fuels with additives such as alcohol or ether can cause premature deterioration of the seal rings.
