If you are a producer of hose products or equipment that makes use of hoses, you'll likely be required, sooner or later, to contemplate your hose couplings and metal ferrules. Investment in even [link widoczny dla zalogowanych] the best quality hose or tubing will be wasted if the hose ferrules are badly chosen or simply inadequate.
## Precisely what is a ferrule?
The term ferrule can refer to many different [link widoczny dla zalogowanych] things across many different applications, but in terms of hose fittings, a metal ferrule is a sleeve or cap that is used to secure a coupling to a hose
## What is a [link widoczny dla zalogowanych] coupling?
A coupling, as the name indicates, is a fitting that allows a hose to be fastened either [link widoczny dla zalogowanych] to an additional hose, or some type of spigot. There are also couplings know as expansion hose fittings [link widoczny dla zalogowanych] that effectively enable a hose of one diameter to couple with a [link widoczny dla zalogowanych] second hose of a larger diameter.
Exactly how do ferrules and couplings work?
The hose coupling has a stem, (usually with barbs) sized to fit snugly inside the hose. The ferrule [link widoczny dla zalogowanych] is placed on the end of the hose, and the coupling is pushed into the same end of the hose through the ferrule. The ferrule is then compressed or " crimped" in order to secure the hose around the stem.
## Sizing
When placing an order for a ferrule, the pertinent measurements are: interior diameter (sized to slip over the hose for which the ferrule is intended), [link widoczny dla zalogowanych] length, and the size of the hole at the end of the ferule (this must be large enough to accept the hose coupling stem). When it comes to couplings the considerations are the outer diameter of the stem (this must be [link widoczny dla zalogowanych] be capable of sliding into the hose), and the length of the stem. The length of the stem must match the length of the ferrule.
## Composition
The numerous applications for which hose fittings and metal ferrules are used call for different performance characteristic and as a result different material composition. Common materials are Brass, Aluminum, and stainless steel. [link widoczny dla zalogowanych] Steel with zinc [link widoczny dla zalogowanych] or nickel plating is also an option. For those applications where the hose is designed to deliver drinking water, lead free brass is a must.
If you've got additional questions about metal ferrules and hose fittings simply go online and seek [link widoczny dla zalogowanych] out qualified manufactures. There exists a great deal of good information available and what questions you cannot immediately resolve can be, certainly, answered by a qualified manufacturer and supplier.
