Crimping Hose Styles that require a positive backstop
To maintain proper fitting position on the hose end during the crimping cycle requires a positive backstop for the hose styles listed below:
2807 and FC186
Teflon
FC120, FC121 and FC172
Thermoplastic
2583
Factory Crimp Style Only
The locator has a built-in spring which allows it to retract as a fitting “grows” or is elongated during the crimping operation. A positive
backstop does not allow this movement. The locator can be converted into a positive backstop by placing the locator collar (DET. 60) in
the recess directly behind the head of the locator. This will prevent the spring from being compressed thus providing the required positive
backstop. The locator collar must be removed during crimping of other styles to prevent machine damage or loss of location adjustment
during end fitting growth.
