Crimping Hose Ends
There are a bunch of different hose crimpers on this page. As you’re looking around, you’ll probably see the one you use. If you don’t see yours, that doesn’t mean you can’t crimp our hose ends with your crimper.
A crimper is a press that squeezes the outside diameter (OD) of the hose end to a final crimp dimension that matches the type of hose, inner diameter (ID) of the hose and the type of hose end being crimped.
Positive Stop verses Programed Crimpers
Some crimpers are positive stop. Which means, if you have the right die and die ring to match your hose and hose end, when the the crimper bottoms out you should have a good crimp. Parker and WeatherHead both offer positive stop crimpers. Other crimpers are programmable. These crimpers, a value is inputted in the crimper to match your die, die ring, hose and hose end and when the crimper reaches that value point the crimper stops and you should have a good crimp. Gates and Aeroquip both offer programmable crimpers. There are many manufacturers making crimpers. As long as you can get the final crimp dimension needed, you can crimp our hose ends with their crimpers.
Checking Your Crimp
Every crimping station needs to have a caliper near. With either style of crimper, you still have to check the final crimp to confirm that you do have the crimp dimension that you’re after. Crimpers can get out of calibration, dies can wear, the crimper isn’t maintained, properly lubricated or is located in a dirty environment can contribute to the final crimp not being correct.
