PentairPool Rainbow Auto Feeder Model 322 / 320 Tube Black 5/8 x 1/2 x 7 3/8 R172091

Based on other reviews, I warmed the whole thing up in hot water before installing. No kinks, correct size, looks fine. Photo is after about 2 months.

This feeder tube fit my older Pentair Chlorinator without issue. Straightforward replacement, quality product.

Even though it was factory spec, I could have been 1 inch longer to eliminate kink in hose. Worked, happy with that.

I was concerned that I ordered this before noticing the negative reviews but fortunately I will not blast the seller since I was able to use it on my pool chlorinator. It is a ridiculous amount of money for the nylon tube you get but that's likely to balance out the amount refunded for the uses that failed and also the cost to mail it. I did heed the comments and left the tube under the sun for a few hours, immediately installed the spring around it and inserted one end in the chlorinator while gradually bending the other end to meet the other. It started to kink so I readjusted the spring to that spot and continued until fully inserted. Tightened the connectors and it worked fine. I think the prices for these parts are a rip off for what they are selling.

This is the most satisfying review I've seen, not to mention how valuable it is in repairing your line feeder. Thanks sooo much for your input and keep up the good work!!!

It is just a hard piece of plastic. To install you need to heat the tube in boiling water to bend it to the desired shape otherwise it may kink.

Worked as expected - will update when durability is ascertained.

Failed due to sun rot after 1 year. Wish I could buy a quality product instead of a piece of junk.
