Specifications

Compatibility

Designed specifically for:

Pentair Rainbow Model 300-29X Automatic Chemical Feeder

This package is model-specific. It should not be assumed to fit Rainbow 320, 322, or other Pentair chemical feeders, which use different replacement components.

When Should the Hardware Package Be Replaced?

The R172275 kit is a convenient option when servicing an older 300-29X feeder showing signs such as:

• Leaking tubing connections
• Worn saddle gaskets
• Damaged saddle clamps
• Corroded or damaged tubing clamps
• Faulty control valve
• Damaged connection fittings
• Missing installation hardware
• Feeder being reinstalled or replumbed

Replacing several aging connection components together can help restore a clean and secure feeder installation.
