Break Line Replacement

[Danzer1]

Seems like there may be some terminology confusion.

The sleeve that goes over the tubing and into the fitting and nut with the beveled edges is called a ferrule - it is required for all compression fittings no matter what the tubing material.

The insert that goes into the tube is required for nylon tube to keep the tube from deforming under compression. It is required for nylon tube but not for steel or copper tube.

Also, if you are reusing the fitting and nut - make sure the ferrule shape and dimensions match the ones you already have or you will have leaks. Not all ferrules are made the same from different fitting manufacturers.

YMMV, Greg

Danzer what is the the insert that goes inside the tubing called?

I was also incorrect. My lines are 3/16" not 1/8". Sorry about the mix up.

This is what I have ordered in 3/16"

They are simply called inserts. Try these:

Shouldn't need anything else. Make sure the fittings are clean, tube square cut, inserted fully (untill seated). Hand tight plus one turn (generally).
