Ultimate Guide to Choose Hydraulic Hose Ferrules

Why does your hose assembly leak? Have you purchased cheap hoses? Or a subpar ferrule? NO! Maybe your ferrule and Hose are both top-notch! Why do leaks exist, though?

We know that the Hydraulic Hose Ferrules are used to assemble couplings and fittings on hydraulic hoses (rubber or PVC hoses with a textile braid or steel wire helix reinforcement).

Fittings for high-pressure hoses are installed on hydraulic hoses and have specialized ferrules to fit. Ferrules have been created explicitly for rubber hydraulic and thermoplastic hoses but are also extensively used in industrial hoses. So, in this article, we’d be looking at the ultimate guide to choosing hydraulic hose ferrules.

What are Ferrules?

Ferrules are the components used to put together high-pressure hydraulic hose fittings. In addition to being widely used in industrial hoses, they are specially made for rubber hydraulic and thermoplastic hoses. In the case of reusable ferrules, ferrules are screwed together, whereas permanent connections are made using crimping machines.

There are many types of two-piece crimp fittings, such as ferrule and insert or one-piece fitting, depending on how the fittings are put together on the Hose.

The hose (Hose) assembly is a typical auxiliary tool used in hydraulic systems, and its parts include sleeves, hoses (or hard tubes), and connecting accessories (such as hose fittings, flanges, etc.).

When operating between -40°C and +100°C, the ferrule is mainly utilized for hydraulic power. To ensure that liquids are circulated, and that liquid energy is transferred, transmit or transport high-pressure media such as water, gas, oil, etc.

To shield the Hose and connection from the elements, the ferrule is attached to the reinforcements and acts as a “weather seal.” Both are frequently constructed of stainless steel or carbon steel, and they may also be plated or coated to increase their resistance to corrosion or chemicals.

Now Market-available hose fittings come in one- and two-piece configurations. The nipple and ferrule are pre-crimped or staked together as a single piece in the one-piece models. Separate hose nipples and ferrules that are crimped together make up two-piece designs.

Leakage will occur if the Hose and sleeve are not compatible or if the size is incorrect. Even if the Hose and sleeve are both of high grade, let’s choose the ideal hose ferrule for the hose assembly as a whole as we look at the various sizes.

How to get your Ferrule Size

00110

For SAE 100R1AT/EN8531SN, 00110 hydraulic hose ferrule Smooth-surface hose size of 1/4″ is distinctive, it has a trapezoidal tooth, and skiving is not necessary.

00110-A

00110-A likewise has a smooth surface and is for the one-layer Hose. Its groove-like look on one end sets it apart from 00110. The interior of this type has a vertical tooth, which is a benefit. It may crimp more firmly to produce a superior crimping effect.

00018

For R7 & R8 thermoplastic hose, use the ferrule 00018.

00210

00210 is for hydraulic hoses made from SAE 100R2AT or EN853 2SN. Its surface is smooth, has trapezoidal teeth, and doesn’t skive when fastened. It is used to reinforce Hose with two layers of steel wire braid.

03310

Although its surface is smooth, it features a vertical tooth and a groove at the end (Identical to 00110A). It is utilized for wire braided reinforced Hose with one or two layers.

00400

It has a smooth surface and trapezoidal teeth and is utilized for DIN EN856 4SP, 4SH, and SAE 100R12. Remember that it is only appropriate for small sizes and only 3/8″ to 1″.

00401

A smooth surface and trapezoidal teeth are utilized for DIN EN856 4SP, 4SH, and SAE 100R12. Remember that it is only appropriate for large sizes, specifically those between 1 1/4″ and 2″.

00402

It fits all sizes and is utilized for DIN EN856 4SP, 4SH, and SAE 100R12.

00TF0

For SAE 100R14 hydraulic hoses, the ferrule 00TF0 is designed. Its inside is smooth and toothless.

00621

This is the model used when employing 6-layer tubes that also need to be skive.

How to Crimp Hose in ferrules

The crimping process involves producing a metal sleeve or ferrule of the Hose fitting with a ring of die segments around it to compress the Hose inside the fitting.

One-Piece Hose Fittings: A pre-crimped ferrule is attached to the Hose, fitting in a one-piece design. The collar won’t fall out of alignment, which is a benefit. The suitable ferrule is linked to the proper hydraulic hose fitting type, thanks to this design. One-piece hose fittings are standard for field maintenance, ideal for straightforward applications, and simple to assemble.

Two-Piece Hose Fittings: The ferrule used with two-piece fittings makes more incredible hose selection and connection versatility. This includes 1SN, 2SN, and multi-spiral hoses, which provide a variety of two-piece fitting and ferrule alternatives to suit the application. Two-piece hose fittings are frequently employed in high-pressure applications, especially where there is a risk of excessive hose vibration and pressure surges. They are made up of an exterior ferrule and an interior serrated hose stem.

Steps to Skive your Hydraulic Hose

After the Hose’s outer cover has been removed, the skive ferrule’s rounded serrations or teeth bite into the wire braiding. In contrast, non-skive ferrules feature pointed serrations that rip through the hose cover.

The steps listed by Strongflex for effective hose crimping are:

Step 1: Choose the inserts, ferrules, and Hose.

Step 2: Using a rotary steel blade, squarely cut the Hose to the desired length.

Step 3: To avoid damaging the steel wire reinforcement, remove the rubber cover to the “skiving length” given if skiving is necessary.

Step 4: Completely attach the ferrule to the Hose. Carefully push in the Hose. Then, “COLLAPSE CONTROL MANOREL” should be selected. MANOREL should be inserted into the insert bore. The MANOREL’s “NO GO” portion must encircle the insert bore entirely. Afterward, take away the MANOREL.

Step 5: The ferrule should be crimped to the diameter of the Hose.

Step 6: Measure the crimp diameter on each die impression to inspect it. The middle of the ferrule length must be used for all measurements. All measurements must be within a tolerance of +0.01-0.2 mm and follow the prescribed crimping diameters.

Step 7: “COLLAPSE CONTROL MANOREL” should be included.

Step 8: The crimping diameter and bore collapse are correct if the “NO GO” portion of the MANDREL stops in the bore.

Step 9: If the MANDREL’s “NO GO” portion passes through the bore, the crimping diameter must be decreased by 0.1 mm.

Step 10: The crimping diameter must be raised if the “GO” portion of the MANDREL cannot pass through the bore.

Conclusion

In conclusion, Hydraulic hose ferrules are crucial parts of the hydraulic hose assembly system because they snugly connect the hose fitting at the hydraulic Hose’s end, ensuring that the hydraulic hose assembly will function properly under the required pressure. We hope this guide has helped in choosing hydraulic hose ferrules.
