Parflex tubing

[Salty]

Does anyone have any warnings about using this tubing?
I put in one of these water filters last Saturday. Checked for leaks ever half hour for the rest of the day and still check it often.
It is a lot different than what I am used to but it seems to be holding just fine.
My concern is, will it fail after a period of time?
The connectin is made with a type of plastic wedge and an o-ring inside of a housing. You just push it into the fitting.

I that like what they call a push-pull circuit. You push it in and it PULLS out??

I've used these fittings and tubing for the last 7 years in my business. I've never had a failure.

Don't ask me about 1/4" copper tubing.

Are you talking about the john guest fittings? They are pretty cool. The tubing inserts into the fitting, the fitting has a retractable sleeve which has barbed fitting that compresses around the tube. (at least thats what I recall it looked like to me) They are really good quality and I have never had a problem with them at all.

It is a good idea to warm the end of the tubing first. I would stick the end in warm, not hot water to make it more pliable. It will return to natural state since the tubing has a memory. It will slip on to the barbs easier, and it should be good to go.

No, not the Qest fittings and there are no barbed fittings.
It just slips into a type of socket. They say to remove it, you press in on the retaining ring and pull on the tube. I didn't try that though!
Here is what it looks like from the directions.
I check it less frequently now and I guess it is going to hold.

I prefer those fittings and have used them on numerous industrial machines. no failures during normal service, they are great.
