Delrin sleeves

Hi, I recently connected an undersink water filter using vinyl tubing and brass compression fittings. Everything works well but when I was in the hardware store the other day I noticed they sell plastic sleeves called delrin sleeves in addition to the normal brass sleeves. Is it ok to use brass sleeves on vinyl tubing or is it going to cause a problem and should I go back and replace them?

Thanks

It shouldn't be a huge issue. I believe the brass ferrules can actually crimp off the plastic tubing if overtightened. I use the correct type now...but in the past I didn't always and never had a real problem.

Pro's should be around.

This image will show how plastic lines should be hooked up to brass fittings, if you don't do it that way you are just waiting for a leak.:NO NO NO:

Thanks for the help. I used the brass inserts but used brass sleeves instead of plastic ones. I will go back and redo the connections with the plastic sleeves. Do you have any recommendation on how tight I need to screw down the compression nuts?

You don't have to get carried away when you are tightening compression fittings on plastic. just make them reasonable, if they leak ( small drips ) you can snug them up with the water on until it stops. Use two wrenches so you don't twist something, luck.

I didn't think the CLEAR SOFT LINES should be used in PRESSURE lines?

That picture is only an illustration, you would have to check out the exact tube to get its pressure rating.
