Know before you buy
Yes, this is a genuine Pentair OEM replacement part designed specifically for compatibility with Pentair and Sta-Rite multiport valves.
Yes, the drain plug includes the required O-ring to ensure a secure, water-tight seal upon installation.
This plug is designed for Pentair multiport valves used on various cartridge and D.E. filter systems. Please verify that your valve requires a .25-inch MPT thread size to ensure a proper fit.
Genuine OEM parts are precision-molded to meet the exact threading and material specifications of your filter. Using the correct part prevents cross-threading and ensures the chemical-resistant plastic holds up against pool sanitizers over time.
You should inspect the plug and O-ring during your seasonal opening or winterization process. If you notice cracks in the plastic or if the O-ring appears flattened or brittle, it is time to replace them to prevent leaks.
