Here are multiple hydraulic hose specifications, and hydraulic hoses can be categorized into skive hydraulic hose and no-skive hydraulic hose based on the hydraulic hose cover.
In this guide, let’s see the skive vs no skive hydraulic hose, and this is the explanation of the advantages of skive versus no skive hydraulic hose.
What Is Skive Hydraulic Hose?
Skive refers to the fact that you need to remove or shave some parts of the hydraulic hose cover, and/or inner tube prior to the hydraulic hose ends to fit the size of the hydraulic hose fittings, for hydraulic hose assemblies.
The skive hydraulic hose has a thicker hydraulic hose cover; you have to shave some layers of hydraulic hose rubber cover to make it much slimmer and thinner to make it much easier to insert into the hydraulic hose fittings.
The hydraulic hose skiving machine can help you shave the hydraulic hose cover, making it suitable for the hydraulic hose fitting size, to connect the hydraulic hoses to complete the hydraulic hose installation.
Here we have a hydraulic hose SAE 100r1A/DIN EN853 1ST with a thicker hydraulic hose cover. This is for you to use the hydraulic hose skiving tool to shave hydraulic hose cover rubber during the hydraulic hose assembling process.
And this is the video showing you how to skive the hydraulic hose.
What Is No-Skive Hydraulic Hose?
The no-skive hydraulic hose is designed without needing the skiving step, this is the ready-to-assemble hydraulic hose, and the non-skive hydraulic hose is manufactured with the thinner hydraulic hose, compared with the skive hydraulic hose.
PS: Sometimes, the “No-Skive” is printed on the hydraulic hose layline, which can tell the hydraulic hose technicists don’t need to use the hydraulic hose skiving blade to remove the hydraulic hose cover. And the “No-Skive” hydraulic hose is applied widely due to the convenience of assembling hydraulic hose.
Why Skive Hydraulic Hose?
Skiving is a process of preparing the end of a hydraulic hose for the attachment of a fitting. It involves cutting away a portion of the hose wall at an angle to create a chamfer. This chamfer allows the fitting to slide over the hose end more easily and create a more secure seal.
Here are the primary reasons why hydraulic hoses are skived:
- Improved Seal: A properly skived hose end provides a better seal between the hose and the fitting. This helps to prevent leaks and ensure the safe and efficient operation of hydraulic systems.
- Easier Installation: Skiving makes it easier to install fittings onto hydraulic hoses. The chamfered end allows the fitting to slide on more smoothly, reducing the risk of damage to the hose or the fitting.
- Reduced Wear and Tear: A good seal between the hose and the fitting helps to reduce wear and tear on both components. This can extend the lifespan of the hydraulic system.
- Safety: Preventing leaks in hydraulic systems is crucial for safety. A properly skived hose can help to minimize the risk of leaks and the associated hazards.
Skiving is an essential process for ensuring the safe and efficient operation of hydraulic systems. By creating a better seal between the hose and the fitting, skiving helps to prevent leaks, reduce wear and tear, and improve overall system performance.
Difference Between Skive VS No-Skive Hydraulic Hose
The difference between the skive hydraulic hose and the non-skive hydraulic hose is the thickness of the hydraulic hose cover. The thicker hydraulic hose cover needs to be shaved before crimping the hydraulic hose into the hydraulic hose fittings.
Manual Skiving of Hydraulic Hose with a Knife
Disclaimer: While manual skiving can be done, it requires precision and skill. Incorrect skiving can lead to leaks or damage to the hose. For critical applications, consider using a hydraulic skiving machine.
Tools Required:
- Sharp utility knife or a specialized skiving knife
- Cutting board or a flat surface
- Marking pen
Steps to skive hydraulic hose manually:
Step 1: Prepare the Hose:
Ensure the hose is clean and free of debris.
Measure the required length and mark it.
Step 2: Cut the Hose:
Using a sharp utility knife or a specialized hose cutter, cut the hose at the marked point.
Step 3: Mark the Skive Angle:
The skive angle typically ranges from 4° to 15°, depending on the hydraulic hose type and fitting. Consult the fitting manufacturer’s guidelines for the recommended angle.
Use a protractor or a template to mark the skive angle on the end of the hose.
Step 4: Start Skiving:
Place the hose end on a cutting board or a flat surface.
Begin skiving by making shallow cuts along the marked angle, gradually deepening them until the desired skive depth is achieved.
Use a firm, steady hand to ensure a clean, even skive.
Step 5: Check the Skive:
Inspect the skive for any irregularities, such as burrs or unevenness.
If necessary, make minor adjustments to the skive.
Tips:
- Practice: Skiving requires practice to master. Start with scrap hose to get comfortable with the technique.
- Sharp Knife: A dull knife will make it difficult to achieve a clean skive and can cause damage to the hose.
- Support: While skiving, support the hose to prevent it from bending or twisting, which can affect the skive angle.
- Fitting Compatibility: Ensure the skived hose end is compatible with the fitting you plan to use.
Remember: For critical applications, especially those involving high pressures or corrosive fluids, it’s highly recommended to use a hydraulic skiving machine to ensure precise and consistent skiving.
Conclusion
In conclusion, both skived and no-skive hydraulic hoses have their own advantages and disadvantages. Skived hoses are generally more durable and have a longer service life, while no-skive hoses are easier to install and maintain. The best type of hose for your application will depend on a number of factors, including the type of fluid you are using, the operating pressure, and the temperature range.
