Pentair Rainbow 10 in. Chlorinator Extension for 320 and 300 Feeders (R172087)
About double the tablets between refills.
Pentair R172087 is the 10 in. chlorinator extension for Rainbow automatic chlorine and bromine feeders, including the in-line Model 320 and the free-standing 300 series. Pentair says the 10 in. extension approximately doubles the tablet capacity and the time between refills. PST SKU PST-_R172087.
Why PST Customers Pick This
Roughly Double the Capacity
Pentair says the 10 in. extension approximately doubles the tablet capacity and the time between refills, and the larger chamber allows more erosion of the tablets.
Screws On, Locks In
The extension screws on tightly over a clean, silicone-lubricated O-ring and is secured with a lock screw. Pentair's parts breakdown lists the bottom-collar lockscrew (R172078) and O-ring (R172009).
Re-Set the Feed Rate
The larger chamber dispenses more chlorine at the same valve setting, so Pentair calls for several days of monitoring after installation to readjust the feeder output.
Model 320 and 300 Series
Pentair's extension sheet covers the #320 in-line feeder and free-standing #300 series feeders, and notes that it does not apply to the large-capacity #300-19 or #300-29.
Silicone Only on the O-Ring
Pentair warns never to use oils or grease on the O-ring, because oil in contact with trichlor or bromine may cause a fire. Use Lifegard silicone O-ring lubricant only.
Secure Free-Standing Feeders
On free-standing #300 series feeders, Pentair says to secure the base of the feeder so the added height cannot tip it over.
Chemical Safety
Use only clean trichlor or clean bromine slow-dissolving tablets in the feeder, and never mix them with calcium hypochlorite or any other chemical: Pentair warns that fire or explosion may result. Take care when removing the cap and do not inhale the fumes.

Frequently Asked Questions
How much more tablet capacity do I get?
Pentair says the 10 in. extension approximately doubles the feeder's capacity and the time between refills. The 20 in. extension, R172283, approximately triples it.
Will it work on a 300-29 feeder?
Pentair's extension sheet notes that it does not apply to the large-capacity #300-19 or #300-29 feeders.
Do I need to change the feeder setting afterward?
Pentair says the larger chamber dispenses more chlorine at the same valve setting, so several days of monitoring are needed after installation to readjust the output.
How does it install?
Follow the recharging steps up to filling with tablets. With the O-ring clean, lubricated with silicone and in place, screw the extension on tightly and secure it with the lock screw, then fill with tablets and finish the normal recharge.

This costume is legit. It has the sparkle, glittery sheen to it like the one used on screen! Very happy with it!!
Excellent service!
PST was great at communicating the status of my order throughout the various stages. I actually did encounter a shipment issue and they handled it without issue. I will be doing business again with them.

as described, fast shipping
My wife has RA and is always uncomfortable. Our hot tub heater failed and all the local shops were not able to assist until November. I was able to order an exact replacement part which was delivered within 3 days the hot tub was up and functioning in three days. I was very impressed with the quality and service.
Good quality just ordered wrong size and also need thicker cover
Fit perfectly, and fast shipping
Super fast shipping and reliable product !
I accidentally broke the original **** by tightening it too much. This was a perfect fit and works 100%. Fast delivery too!
Swapped out broken heater (lasted about 6 years) for this one. The instructions are for the electronics, not for the plumbing. You must get everything perfectly aligned or the plumbing may leak. I needed to loosen the electronics box to get the plumbing perfectly aligned. I have hot water again.
Great prices, fast shipping, great products
Haven't received yet but I'm sure it'll be great
Ordered on Saturday and we're delivered by Tuesday! Great products and great prices!
PST pool supplies are great to work with. I was having trouble finding this heat exchanger . Everywhere I looked, it was out of stock or back ordered. I contacted the manufacturer about buying the heat exchanger. They told me I couldn't buy it because I wasn't a dealer. If I was a dealer, they would be able to take the order. And make one, it would take 5 to 8 weeks. I contacted PST they put my order in and I received it in about six weeks. Fantastic people to work with. Thanks Tim
