When working with a hydraulic hose, fittings must be added to either end to connect it to other parts of the system. That’s when to use a hose crimping tool, which conjoins two pieces of metal by deforming one or both. To get the best results, here is a brief overview of how to crimp a hydraulic hose.

4 Steps for Using Hose Crimpers Successfully

1. Measure the Hose Carefully

Don’t assume that each end of a hose will have the same diameter. Measure each end carefully to establish their outside diameter, then select hose crimpers that will fit those measurements.

2. Draw a Line Around the Hose

After smearing the end of the hose with lubricant and pushing the fitting in as far as it will go, use a piece of chalk to draw a line around the end of the fitting. This will help you check the integrity of the fitting when the crimping is complete.

3. Start the Machine

Follow the manufacturer’s directions carefully when using hose crimpers. This is especially important for using the micrometer, which sets the diameter at which the machine will stop crimping. Use the micrometer setting and crimper die specified by the manufacturer, as they can vary from machine to machine.

Put on safety equipment, including earplugs, goggles, and gloves, and turn on the crimper. It will squeeze the outside diameter (OD) of the hose’s end to a dimension that matches the hose’s inner diameter (ID). When complete, the machine will stop.

4. Check & Test

Check the chalk mark you made on the hose. If it’s no longer at the base of the fitting, this indicates the hose or fitting moved, and the crimping isn’t tight. If the mark remained in place, the hose is properly crimped. Test the assembly by following the recommendations provided by the manufacturer.
