About This Item

The Pentair Winterizing or Isolation Plug (R172367) is the OEM replacement plug for the Pentair Rainbow 300, 302, 300-19, and 300-29 automatic pool and spa chemical feeders.

This plug attaches to the control valve of the automatic feeder, isolating the unit from the plumbing circuit during winterization or whenever the feeder needs to be taken offline for service. Capping the control valve port prevents water from entering or exiting the feeder when it is not in use, protecting internal components during off-season storage or maintenance periods.

Specifications

Pentair Part Number R172367
Part Name Winterizing or Isolation Plug
Quantity Included Each

Pro Tip

Before ordering, confirm the part number stamped or molded on your existing plug matches R172367. If your feeder is being winterized, install this plug after fully draining and rinsing the feeder body — capping a wet feeder with residual chemical inside can cause corrosion over the off-season.

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.
