5 ATCO recommends barrier style air conditioning hose to be used with beadlock fittings. All-rubber hose may also be coupled using beadlock style fittings. ATCO only recommends the use of barb fittings with all-rubber hose coupled with face style crimp or worm gear clamps. Bubble style crimps are not recommended. Approved crimping equipment is located in the HOSE CRIMPERS AND TOOL section of this catalog.
