How To Choose Ferrules According To The Tubing Type

If you buy double ferrule including front ferrule and back ferrule, the tubing should be polished. The double ferrule is not suitable for the blank tube. The sealing is not good.

If you use the blank tube, it is advised the single ferrule, which sealing is good for the blank tube.

It is very important to choose ferrules (Double ferrule or single ferrule) according to tubing type. If you mistake the ferrules and tubing type, the loss will be big.
