Product details

The Pentair R172375 is the lock screw for Rainbow automatic chemical feeders. It is the genuine Pentair part, listed for the Rainbow feeder models HC-3315, HC-3330 and 3340.

A small part that stops the job

Threaded hardware on a chemical feeder lives a hard life. It is exposed to concentrated chemistry, it gets handled every time the feeder is refilled, and it is the first thing to go missing during a service. A stripped or absent lock screw is enough to leave a feeder that cannot be closed up properly.

Ordering

Quote R172375. Rainbow hardware looks similar across the range, and the part number is the only reliable way to get the right one. The lock ring and lock spring are separate parts, so check those at the same time.

Questions and answers

What people ask about this product, answered by our pool techs.

Which feeders does this fit?
It is listed for the Pentair Rainbow automatic feeder models HC-3315, HC-3330 and 3340.
Is this a genuine Pentair part?
Yes. It is the Pentair Rainbow OEM lock screw, part number R172375.
How many do I need?
That depends on how many are missing or damaged on your feeder. This listing is for the lock screw itself, so count what your unit takes before ordering.
What else should I check while I am in there?
The lock ring and the lock spring are separate Rainbow parts and they wear alongside the screw, so it is worth looking at both while the feeder is apart.
