Pentair 2" NPT Drain Adapter Fitting

The Pentair 2" NPT Drain Adapter Fitting (Part #24900-0510) is a genuine OEM replacement thermoplastic plumbing component designed primarily for Sta-Rite pool and spa cartridge/D.E. filtration systems, including the System 2 PLD and PLM series. Featuring a heavy-duty, corrosion-resistant molded construction, this adapter threads securely into the lower tank vessel's drainage port using a standard 2-inch National Pipe Taper (NPT) male connection. Its primary role is to provide a leak-free, structurally sound transitional hub that allows pool owners to attach external discharge hoses, drainage valves, or temporary waste lines when completely emptying the tank core for winterization or seasonal element cleaning.

Because it is a single hollow piece of molded thermoplastic, it is compact and lightweight, with an actual product weight of approximately 0.25 to 0.35 pounds (roughly 4 to 5.6 ounces) and a packaged shipping weight of just under 0.5 pounds.
