About This Item

OEM Replacement Diverter Tee for the Pentair In-Line Automatic Feeder

The Pentair Diverter Tee (R172317) is the OEM replacement fitting for the Pentair 320 In-Line Automatic Feeder, providing the 1-1/2" NPT x 2" slip connection that routes water flow through the feeder body.

This fitting controls the directional flow of water entering and exiting the automatic feeder. A cracked, warped, or leaking diverter tee compromises the feeder's ability to draw water through the chemical chamber at the correct rate, leading to inconsistent sanitizer output. Replacing a damaged tee with the correct OEM fitting restores proper flow dynamics and maintains a reliable seal at both the NPT and slip connections.

Pentair In-Line Automatic Feeder — Sanitizer & Water Quality Series 320 1-1/2" NPT x 2" slip connection

Compatibility is based on Pentair parts documentation and available OEM records. This is not an exhaustive list. For certainty, verify the part number in your equipment's manual or on the original part itself before ordering.

Pro Tip

Before ordering, confirm the connection sizes on your existing tee — the inlet side is 1-1/2" NPT (threaded) and the outlet side is 2" slip (solvent weld). These two sizes are not interchangeable with other diverter tee variants. If your feeder plumbing uses a different configuration, verify against the part number molded or stamped on the original fitting before adding to cart.
