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

Earl’s Perform-O-Flex™ stainless braid protected synthetic rubber hose is the premium quality racing hose depended on by the top racing teams of every professional sanctioning body in the world.

The pressure ratings shown are only valid when Perform-O-Flex™ hose is used with either Swivel-Seal™ or Auto-Fit™ hose ends. The use of other manufacturers’ hose ends is not recommended. If you are going to pay for the best — demand it. Insist on Earl’s Perform-O-Flex™ hose and Swivel-Seal™ or Auto-Fit™ hose ends.

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
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 PERFORM-
O-FLEX™ hose.
