1. Start with the hose you are fitting

According to the product description, these ferrules are designed for rubber hydraulic hoses and thermoplastic hoses, and they are also used on industrial hoses. Before anything else, confirm which type of hose your assembly uses. If your application uses a different kind of hose, check with the supplier first. Do not assume the fittings are compatible.

2. Choose two-piece or one-piece construction

Hydraulic hose crimp fittings are grouped by how they are assembled on the hose:

• Two-piece fittings: the ferrule and the insert (stem) are separate parts. They are swaged together, which locks the hose between the serrated dies of the ferrule and the stem.
• One-piece fittings: the ferrule and insert are crimped to a predetermined diameter.

Tell the supplier which construction your assembly process uses.

3. Decide between permanent crimping and reusable ferrules

The product description names two assembly methods:

• Crimped: the ferrule is assembled on a crimping machine and makes a permanent connection.
• Screwed (reusable ferrules): the ferrule is screwed on instead of crimped.

If you choose crimped fittings, the crimping must be done precisely to get a proper seal. The source describes a proper seal as vital for preventing leaks and system failures. Make sure your crimping equipment and process can handle the fittings you order.

4. Confirm dimensions: hose size and thread side

The product description lists hose size as one of the main selection factors. The ferrule and stem have to match the hose they will be crimped onto. On the threaded side, the fitting has to match the machine port.

There is no single international standard for hydraulic fittings. Several standards are used side by side in the market. The product description says the manufacturing program covers most of these standards. Even so, state the exact standard, thread type and size you need in your inquiry. Do not assume a standard will be chosen for you.

5. Identify the medium being transported

The type of fluid going through the hose is another selection factor named in the source. Tell the supplier which fluid your system uses so they can check that the fitting suits it. This guide makes no claims about compatibility with any specific fluid.

6. Match operating pressure and environment

The product description says ferrule fittings are designed for high-pressure hydraulic hoses. It also says their ability to withstand pressure is a main reason they are used in construction, agriculture and manufacturing. Still, you need to state your system's actual operating pressure when selecting a fitting. This article does not give a pressure rating, and none should be assumed.

The fitting material also has to suit the environment it will work in, to avoid damage and get a long service life. The source says ferrule fittings are commonly made from materials such as stainless steel or brass, which resist corrosion and wear. Ask which material is offered for the fitting you plan to order, and describe where it will be used.

Buyer checklist

When this guidance does not apply

This guide only covers the general selection factors in the product description. It is not a substitute for confirmed technical data. If your application needs a verified pressure rating, a dimension table, a particular standard, proof of fluid compatibility or a certification, get that documentation from the supplier before you buy. Prices, lead times and certifications are not covered here and have to be confirmed separately.

To request hydraulic hose ferrule fittings, send Hebei Yisizhe Manufacture (Group) Limited the details from the checklist above so the right fittings can be identified.
