About This Item

The Pentair Rainbow No. 176 Axle Assembly (R201470) is the OEM replacement axle assembly for the Pentair Rainbow No. 203 chemical feeder.

What It Does

The axle assembly provides the central rotating shaft support within the No. 203 feeder mechanism, maintaining proper alignment of moving components during operation. Replacing a worn or damaged axle assembly restores correct feeder function and prevents irregular chemical dispensing caused by shaft play or breakage.

Pro Tip

Before ordering, confirm the feeder model number on your existing unit matches the No. 203. The axle assembly design varies between Rainbow feeder models — ordering for the wrong model number will result in a non-fitting part. Match the part number stamped or molded on the original component to R201470 before adding to cart.

Pentair is often considered the "gold standard" for pool professionals, and for good reason.

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.
