Do you know the steps instruction hydraulic standard fittings wholesale for making a hose assembly? Crimping a hydraulic hose is a crucial aspect of any hose assembly. With several fluids or gases in motion over extended periods of time, the crimp should be just right so that the hose does not damage the application. Today we will talk about how do we crimp the hydraulic hose and fittings.


Step 1:Prepare the tools which you need.

There are some tools which will be used in operation.

  1. Appropriate safety clothing – goggles, ear protectors, gloves
  2. Hose
  3. Attachment
  4. Grease or lubricant for the hose end to facilitate ease of inserting the attachment
  5. Marker or chalk to mark the hose for the correct length to match the attachment
  6. Crimping machine with the correct die and collar for the hose diameter, and compression ring.Vernier callipers to check the finished crimp (optional)

Step 2:Measure and cut the hose

Measure the length of the hose that you need and cut it to the necessary size.


Step 3: Marking The Hose Length To Match The Attachment Depth

In order to easily push the hose into the attachment you need to lubricate the end of the hose. Then push it as far as possible into the attachment. Next, draw a line on the hose to mark where the fitting ends so that you can double-check it has been done properly after crimping.


Step 4:Clean the hose and load in the correct specifications

Choosing the correct specification is important.Cleaning the hose will reduce contamination and hose assembly failure.


Step 5:Select the die

Crimper dies are specifically designed for certain hoses and fittings, so make sure to verify the die is set to the correct specifications.


Step 6:Place the hose in the crimping machine and ready to crimp the hose

Push the end of the hose into the crimping machine and through the die so that the hydraulic hose fitting appears above the die. The top of the hose, now concealed inside the fitting, should not be above the die.And then you can turn on the machine and begin crimping.Do not touch the machine until the collar is firmly at the bottom of the die.


Step 7:Check it

Checking the chalk mark which you made on the hose and make sure the hose is finished to the correct crimp diameter. If it is no longer at the base of the fitting, it means the hose or the fitting moved during the crimping. However tight it may seem, this is not a good crimp. Otherwise, if the chalk mark is in place, you have successfully crimped the ends of the hydraulic hose.


Step 8:Cap hose assembly

After you clean the hose again, it is a good idea to cap the assembly on both ends. You can use plastic caps or heat shrink caps.
