About This Item

The Pentair 354265 is the OEM stainless steel hex washer head screw for the Challenger pump strainer pot and select Pentair filter housings, including the WaterFall™, Hydropump, Star Polymeric, Sand Dollar, and Star Fiberglass filter lines.

What It Does

This screw secures the strainer pot cover on the Challenger pump and serves as the housing fastener on compatible Pentair filter models. Using the correct OEM fastener ensures proper thread engagement and maintains a secure, leak-free seal at the strainer pot. Match the thread specification (5/16"-18) and drive type to your original hardware before ordering.

Pro Tip

When replacing strainer pot screws, inspect all screws in the set — corrosion or thread wear rarely affects just one. Replace the full set at the same time to ensure uniform clamping force and prevent a return visit. Match the thread specification (5/16"-18) and length (3/4") stamped or printed on your original hardware before ordering.

For the DIY homeowner, Pentair represents the intersection of rugged durability and silicon valley-tier technology. They pioneered the Variable Speed Pump revolution with the IntelliFlo®, saving American pool owners millions in energy costs. Today, their ecosystem focuses heavily on automation, allowing you to control your pump, heater, lights, and chemistry from a single app. While they are a favorite among professional builders, their "EC" (E-Commerce) line of equipment allows homeowners to access pro-grade technology with valid warranties for DIY installation.
