Earl's Form-A-Flex radiator and heater lines set a new standard for flexible water lines. Manufactured from corrugated 300 series stainless steel tubing, their corrosion resistance is not skin deep-it is absolute.

There is no plating to flake off or rust through. They can be permanently bent by hand in tight radii and still remain flexible enough to absorb engine vibration and rock.

Form-A-Flex brings the quality you expect from Earl's® --the industry leader in high-performance and racing plumbing-- to the street rod and show car markets. Nothing on the market compares to Form-A-Flex.

The connector sleeves at each end of the Form-A-Flex tubing are made from the same silicon rubber used in Indy cars.

The full worm gear hose clamps are enclosed in a housing machined from a billet of 6061-T6 aircraft aluminum that is either bright dip anodized or chrome plated.

For many years, street rod and show car enthusiasts have faced the problem of finding radiator and heater lines that match the appearance of the rest of the vehicle. The original equipment-type molded black rubber hoses, while efficient and inexpensive, leave a lot to be desired in the appearance department. The tortuous bends often required to clear front engine accessories usually preclude the use of relatively inflexible stainless steel braid protected elastomeric hoses such as Earl's Auto-Flex. Further, the inherent stiffness of this type of hose imposes substantial loads on the soldered radiator inlet and outlet necks--especially when the engine rocks on flexible mounts.
