Pentair 1 in. Threaded Union | High Capacity Automatic Feeder | R270531

The Pentair R270531 is the OEM replacement 1-inch threaded union for the High Capacity Automatic Chemical Feeder series, providing a secure, serviceable plumbing connection at the feeder inlet or outlet.

The threaded union allows the chemical feeder to be disconnected from the plumbing line without cutting pipe — essential for routine service, chemical refills, and feeder removal. A worn or cracked union can result in chemical leaks at the connection point; replacing it with the correct OEM part restores a leak-free seal and maintains the integrity of the chemical feed circuit.

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

If you're replacing a failed or leaking union, inspect the mating threads on the feeder body at the same time. Chemical feeders are exposed to concentrated sanitizers that can degrade threaded fittings over time. Replacing the union while the feeder is already out of service is the right moment to confirm the body threads are still sound — before reassembly.
