Compatibility and Feeder Matching

How do I confirm the R172272 elbow fits my Rainbow feeder?

If your feeder uses a 1/2 inch threaded elbow connection for the chemical feed line, this fitting is the correct match for Rainbow 320 and 322 units. Bringing photos to the store helps staff verify compatibility quickly.

Will this elbow work on older Rainbow 300-series feeders?

Yes, many 300-series units use the same elbow layout and thread size, making this a common replacement.

Can a worn elbow cause feeder leaks?

Yes, cracked elbows or damaged threads often cause slow drips or pressure loss around the feeder body.

What should I check before installing the new elbow?

Inspect the feeder port threads and ensure the sealing surfaces are clean. Proper alignment helps prevent leaks after installation.

Does the included nut help improve sealing?
