RO canister is leaking

My RO canister starting leaking about a month ago. I've tried teflon tape and bought a new o-ring but it is still leaking. Does anyone have any other suggestions? I'm starting to think I should just buy a new canister.
 
Did you check to make sure all the threads are clean? Is the housing or canister cracked?

I had one that had a very slow leak when under pressure. Regular Teflon tape didn't stop it, but the thicker pink tape worked on mine, might be worth a try.

I didn't see anything. I've taken it apart several times and washed the top off. It just started leaking one day. Hadn't been apart for months.

I didn't realize it came in different sizes. I will have to stop by Home Depot this weekend and get some.

Also, make sure you aren't over tightening it, that will cause leaks and or cut the o-ring.

It is leaking where you screw the top on. I've read to use silicone on the o-ring but I don't know which silicone to get. I don't want to use something that will contaminate the water.

Is this the silicone I need:

Id use a food grade lubricant. Such as this.

By the time I pay shipping it would be just as cheap to buy a new canister.

The one I linked says it can be around food. I assume that is not the same as food grade.
 
For o rings and bulkhead gaskets I use this
