Pentair Chlorinator Tube Black R172091 OEM

The Pentair Tube Black (R172091) is a genuine OEM replacement feeder tube designed for use in Pentair Rainbow automatic chlorine and bromine feeders, specifically Models 320 and 322. This internal tube plays a critical role in directing treated water through the feeder, ensuring proper chemical dissolution and consistent sanitizer delivery into the pool or spa system.

Over time, feeder tubes can become brittle, discolored, clogged, or cracked due to continuous chemical exposure. When this occurs, feeders may experience restricted flow, uneven chemical distribution, or leaks. Replacing the tube helps restore proper feeder operation and ensures accurate sanitizer performance.

Manufactured to Pentair’s original specifications, this replacement tube ensures correct sizing, material compatibility, and long-term durability in harsh chemical environments.

Feeder performance depends on unobstructed internal flow.

Why this matters:

• Ensures proper water flow through the feeder

• Prevents leaks and internal restrictions

• Restores correct feeder operation

• Extends the life of the chemical feeder

Designed for Pentair Rainbow Feeders

The R172091 black tube is designed specifically for Pentair Rainbow Model 320 and 322 in-line automatic chemical feeders. Proper fit is critical, as incorrect tubing can affect flow rates and feeder efficiency.

Always verify feeder model compatibility before installation.

Chemical-Resistant Construction

This tube is constructed from materials engineered to withstand constant exposure to chlorine or bromine. Its design maintains flexibility and internal diameter under normal operating conditions, helping prevent premature failure and flow restriction.
