Auto-Flex™ Hose

A stainless braided hose at a price competitive with the imports. Earl's Auto-FlexTM HTE stainless braid-protected synthetic rubber hose is manufactured to our specifications in the U.S.A.

Earl's Auto-Flex HTE 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 imbedded 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.

Auto-Flex hose is intended for use with Swivel-Seal, Auto-Fit and Auto-Mate hose ends only. No other Earl's hose ends are intended for use with Auto-FlexTM hose. The use of other manufacturers hose ends is not recommended.

Features
A Partial Coverage Textile 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. 
B The Inner Liner constructed from synthetic rubber tube, clean and fast flowing, provides constant flow at operating temperatures from -40° to +300ۥ F.
C Full Coverage 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 Perform-O-Flex hose.

** Pressure limiting factor will be the hose clamp. The hose limit far  exceeds any pressure obtainable by clamping.
*** Only Econo-O-Fit available for these sizes.

In recent years various fuel manufacturers may have added any number of new unpublished additives to their blends. It is therefore very difficult to know how the tube compound used in the inner liner of our Super-stock, Auto Flex and Perfor-O-Flex or any other brand of elastomeric hose will react with a specific fuel. Because of the unknowns described above, we are unable to guarantee that the below listed hoses are the best possible products to use with any specific fuel. If in doubt use Teflon lined hose. Auto-Flex hose is not to be used with brake fluid.
