Pentair Drain Plug with O-Ring

The Pentair Drain Plug with O-Ring Assembly (most ubiquitously associated with OEM universal Part #192115Z or #27001-0022) is a vital plumbing hardware component utilized across nearly all Pentair and Sta-Rite pool and spa equipment lines, including IntelliFlo, WhisperFlo, and SuperFlo circulation pumps, as well as Triton II, Tagelus, and System 2/3 sand or cartridge filters. Injection-molded from a high-impact, chemically inert thermoplastic polymer, this small male-threaded plug screws directly into the lowest drainage ports of pump strainers or filter tank basins. Its primary maintenance function is to facilitate routine system draining during cold-weather winterization or internal component cleanings, while the included synthetic nitrile rubber (Buna-N) O-ring compresses under hand-tightening to establish an absolute airtight and watertight seal. By sealing this crucial boundary, the assembly prevents hazardous vacuum drops or localized pressure leaks that would otherwise cause a pump to lose its prime or spit pressurized water during active filtration cycles.

As a highly compact plastic and rubber component, its weight footprint is practically negligible:

• Actual Product Weight: Approximately 0.02 to 0.05 pounds (roughly 0.32 to 0.80 ounces).

• Packaged Shipping Weight: Typically scales at 0.08 to 0.15 pounds due to the protective parts padding or standard bubble-mailer envelope used during transit.
