Pentair Rainbow Tube Fitting with Compression Nut, 3/8" | R172032Z

The Pentair R172032Z is a 3/8" tube compression fitting with an integrated compression nut used on select Pentair Rainbow automatic chemical feeders and IntelliChem® chemical controller plumbing. This fitting creates a secure, leak-resistant connection between small feeder tubing and the feeder/controller port, helping maintain consistent sanitizer feed and preventing air intrusion or drips at the tubing connection.

Key Features

  • 3/8" tube fitting designed for small feeder tubing connections.
  • Compression nut included for a tight, secure seal on the tubing.
  • Direct replacement for cracked, stripped, or leaking tube fittings.
  • Helps prevent suction/flow issues caused by small air leaks in feeder tubing lines.

Compatibility

  • Pentair Rainbow automatic feeders: Models 300, 302, 300-19, 300-29
  • Pentair IntelliChem® chemical controllers: where the parts diagram calls for R172032Z
  • Other applications: compatible installations that specify a 3/8" tube compression fitting (R172032Z)

Specifications

  • Brand: Pentair / Rainbow
  • Part Number: R172032Z
  • Part Type: Tube fitting with compression nut
  • Tubing Size: 3/8"
  • Quantity: Sold individually

Common Reasons to Replace

  • Slow drips or moisture around the tubing connection
  • Cracked fitting body from age, chemical exposure, or freeze damage
  • Compression nut won’t tighten properly or threads feel stripped
  • Brittle tubing no longer seals well (often replaced at the same time)

Installation Notes

  • Shut off the pump and relieve system pressure before servicing feeder/controller tubing.
  • Cut tubing cleanly and square, then fully seat it into the fitting before tightening the compression nut.
  • Tighten snugly—avoid over-tightening, which can crack plastic fittings or deform tubing.
  • After restart, check for seepage during the first few run cycles and re-snug if needed.

Maintenance Tips

  • Inspect feeder/controller tubing and compression fittings seasonally for brittleness, cracking, or discoloration.
  • Keep water chemistry balanced to reduce scaling and chemical stress on small plastic fittings.
  • If you see minor seepage, address it early—small leaks can become larger and may affect dosing consistency.
