Pentair 2" FNS24 All Purpose Plug with O-ring

The Pentair 2" FNS24 All-Purpose Plug with O-ring (Part #195830) is a genuine OEM threaded replacement plug assembly designed primarily for the Pentair FNS, FNS Plus, and commercial pool/spa Diatomaceous Earth (D.E.) or cartridge filter lines. Molded from a high-impact, chemical-resistant thermoplastic polymer, this 2-inch plug seals secondary port openings or specific drainage configurations within the filter plumbing manifold. It features external male pipe threads and comes equipped with a tight-fitting synthetic rubber O-ring to ensure a completely airtight and watertight compression seal, preventing localized pressure leaks and system priming issues.

Being a small, hollow plastic plumbing fitting, it is exceptionally lightweight:

• Actual Product Weight: Approximately 0.02 pounds (about 0.32 ounces).

• Packaged Shipping Weight: Typically scales at 0.08 to 0.10 pounds due to the protective parts bag or standard bubble mailer envelope used for transport.
