Holedall couplings are not to be used with plastic lined chemical hose. Consult Dixon for recommendations on usage.
Holedall couplings (Externally Swaged), to perform satisfactorily, must be applied properly in accordance with Dixon's assembly

Media being transported through the hose should be compatible with the
stem material. Compatibility of ferrule material with the environment in which it will be used is recommended. Consult these
Compatibility Chart on pages 802-807 or contact Dixon for material compatibility. For applications other than the ones listed,
please consult Dixon.
