AUTO-O-FLEX™HOSE - For use with Swivel-Seal™, Ano-Tuff™ and Auto-Fit™ hose ends

Earl’s Auto-Flex™ hose features a recommended temperature range and maximum operating pressure equal to our premium quality Perform- O-Flex™ hose… at a much better price. A partial
coverage textile inner braid is embedded in the HTE™ liner during manufacture. The hose is finished with a full coverage stainless steel braid which is bonded to the reinforced HTE™ liner. Continuous use temperature rating is -40˚ to +300˚F.
The pressure ratings shown are only valid when Auto-Flex™ hose is used with either Swivel-Seal™ or Auto-Fit™ hose ends. The use of other manufacturers’ hose ends is not recommended..

 Partial Coverage Stainless Steel Inner Braid is woven into the inner liner of high-temperature synthetic rubber. The timing of the braiding and the curing of the rubber during construction are the key to achieving the desired flexibility and mechanical bond between the braiding layers. Beware of cheaper hoses that do not have this critical mechanical bond.
The Inner Liner constructed from Temprel synthetic rubber tube, clean and fast flowing, provides constant flow at operating temperatures from
-40° to +300 F.		 Full Coverage Outer Braid of High Tensile Stainless Steel bonded to the hose liner provides maximum pressure capabilities, while maintaining the beauty, and flexibility that is responsible for the popularity of AUTO-FLEX™ hose.
