DFNIDY Pool Chlorinator Tube Kit R172091 + R172272 Elbow for Pentair Rainbow 320/322

DFNIDY Pool Chlorinator Tube Kit — a practical replacement for Pentair Rainbow feeders

Keep your pool and spa chemistry steady with a replacement hose kit designed for Pentair Rainbow feeders. The DFNIDY set blends flexible PVC tubing with reliable fittings to support consistent chlorine or bromine delivery in inline feeders. Built for ongoing use, it prioritizes ease of routing, smooth flow, and a secure fit to help you maintain your system without disruption. This kit is ideal when routine maintenance or part wear calls for a refresh rather than a full system replacement.

What makes this kit a thoughtful choice is how the pieces work together to simplify service and upkeep. The included tubing, fittings, and spring are sized to streamline compatibility with common feeder models, supporting a straightforward swap that minimizes downtime and guesswork.

What’s included

• 1 x 5/8" OD PVC tubing R172091
• 2 x 1/2" 90-degree NPT tube fittings R172272
• 1 x Tube support spring R171097

Key benefits

• Flexible hose that can bend around pool equipment and valves for easier routing
• Precise replacement parts designed for Pentair Rainbow feeders, notably the 320 and 322 models
• Spring support helps prevent kinking, supporting a steadier flow through the feeder
• Simple, no-fuss installation that lets you swap parts without specialized tools

The kit is compatible with Pentair Rainbow feeder configurations used in many residential pools and spas. The 1/2" 90-degree fittings provide compact turns and secure connections, while the 5/8" OD tube supports reliable transport of the feeder output. The included tube spring adds a simple safeguard against deformation during routine maintenance, helping you keep a clean, consistent line from feeder to pool water.

In everyday use, you might appreciate the kit when performing routine maintenance, after a hose replacement, or when reorganizing feeder lines to accommodate new pool accessories. The materials are chosen for durability and flexibility, which helps when you need to re-route tubing to accommodate seasonal equipment changes or spa configurations. This set offers a practical, cost-conscious option for keeping your feeder system ready for regular chemical dosing.

Installation tips

• Power off the feeder and close nearby valves before replacing parts
• Remove the old hose, then install the DFNIDY hose, followed by the elbow fittings
• Slide in the tube support spring to prevent kinking and verify tight, leak-free connections
• Test the system briefly to ensure proper flow and seal integrity

Whether for a quick refresh or a planned upgrade, this DFNIDY kit offers a practical path to maintaining steady feeder performance with compatible Pentair Rainbow 320 and 322 models. Consider it as a dependable option when you want to refresh essential components without replacing the entire feeder assembly.
