Question

In a flare-less fitting What takes the place of the sleeve?

Answer 1

In a flare-less fitting, a ferrule replaces the sleeve to create a metal-to-metal seal by compressing onto the tubing when the fitting is tightened.

Step-by-step explanation:

In a flare-less fitting, a ferrule takes the place of the sleeve. Unlike a traditional flared fitting where the sleeve is flared to match the angle of the fitting for a seal, in a flare-less fitting, the ferrule is used to create a seal between the fitting and the tubing. When the fitting is tightened, the ferrule is compressed onto the tubing, deforming to the shape of the tube and the fitting, creating a metal-to-metal seal that does not require flaring of the tubing itself. This makes flare-less fittings suitable for high pressure applications and easier to assemble since they don't require special flaring tools.
