Chemical draw tubing is strange stuff

[OurTown]

We have issues with some of our chemicals eating or making our concentrate draw tubing turn hard quickly. It is just on our JBS Action presoak and the PH booster. The booster will make the tubing much less flexible in a few months and if you go six months it is so brittle that it breaks like a candy cane if you are not careful with it. The presoak is not nearly as bad.

I switched to Excelon tubing about a month ago. It has a surgical tubing like feel and look to it and is supposed to be more chemical resistant.

So far the booster hose still seems flexible and looks good. The presoak hose started to look strange after about two weeks. It looks like it was growing something inside it and this stuff started to plug the hydrominder tip. It started to get hard in the areas that the growth looked the worst so I switched it out for the regular tubing for now. I suppose it is possible we have something wrong with this batch of soap. The jury is still out with the Excelon tubing on the booster. What type of tubing do you use for presoak and booster? Is there one that will last a year or should I just get the cheap stuff and change it every few months?

I used to have the same problem... then I ran this in the few problematic situations

then I got too busy and started having my employees switch out the surgical stuff as it went bad... better to use up their time than mine

I have been using this... https://www.usplastic.com/catalog/item.aspx?itemid=75637&catid=864
Works well for those type of applications.

How long does this Tygon tubing last with PH booster?

I've got some tygon tubing drawing sodium hydroxide that is probably ten years old

Our Dog-Pet Wash specific technology relies on injection for perfect draw from our shampoo etc canisters. It works except we have to be vigilant to make the tubing connections seal 100% replacing with the standard less cost plastic tubing brand new often enough & also with brand new john guest fittings. I wonder if the tygon or if the excelon would better for that concern???

I haven't used Tygon for more than 3 years yet but the original tubing on a high pH booster type product is still pliable.

I don't know about John Guest fittings but I know that it seals really well on hose barbs and stays sealed. We don't get the stretching that lets air get sucked in around the barb.

Over the weekend I talked to Jason at questcarcare.com He says they have good luck with superthane "Ether" hose.
