About This Item

The Pentair Extension Collar (85002300) is the OEM replacement ring seat collar for Pentair skimmers, adjustable to accommodate deck thicknesses up to 3 inches.

This collar bridges the skimmer body and the finished pool deck surface, adjusting the throat height to match the depth of the surrounding coping or concrete. When the original collar is cracked, warped, or missing, water can migrate behind the skimmer faceplate and into the deck substrate. Replacing it with the correct OEM collar restores the proper fit at the ring seat and protects the surrounding deck material from water infiltration.

Poolaroo Pro Tip

Before ordering, confirm the model number molded or stamped on the inside of your skimmer housing. Cross-reference part number 85002300 against your equipment manual to verify this collar matches your deck depth and ring seat configuration before adding to cart.

Pentair is often considered the "gold standard" for pool professionals, and for good reason. Founded in 1966 (originally by five inventors making high-altitude balloons!), the company has evolved into the global leader in smart, sustainable water solutions. 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.
