Common Questions Regarding Metal Ferrules and Hose Fittings

How do ferrules and couplings work?

Firstly, we know that a China ferrule in hose fittings is a sleeve or cap that's utilized to attach a coupling to a hose, while a coupling is a fitting which allows a hose to be connected either to another hose, or some sort of spigot. There are also expansion hose fittings which effectively enable a hose of one diameter to couple with a hose of a larger diameter.

Before connecting hoses, it is a need to familiar with the hose coupling structure. A hose coupling has a stem, which is designed to fit snugly inside the hose. The ferrule is positioned on the end of the hose, and the coupling is pressed into the same end of the hose. The China ferrule is then squeezed or " crimped" in order to fasten the hose around the stem.

How are ferrules and couplings sized?

When considering about the sizes of ferrules and coupling, the essential measurements for a ferrule are: interior diameter, length, and the size of the hole at the end of the ferrule, this hole must be big enough to take the stem coupling. With regards to couplings the things to consider are the outer diameter and the length of the stem.

What are ferrules and couplings made from?

The distinctive applications require China hydraulic fittings of different overall performance characteristic. Popular metal materials are aluminum, brass, and stainless steel. Steel with zinc or nickel plating is also a possibility. For those uses where the hose is designed to deliver drinking water, brass which is lead free is a must.
