Hydraulic Pipes with Universal Flares

Hydraulic piping for British cars has undergone several design changes; with the result that replacement lines often have “flares” that do not look like the lines on the car.

For example, if the flare on the old line looks like (1a), the new line (2a) will look incorrect.

All of the lines Moss sells now have what is known as a “universal flare” (2a). This is actually the result of a need for the various manufacturers of modern hydraulic lines to come up with a flare that would work no matter which of the four types of coupling the car had. The practical need for such a flare is obvious. Most people are not able to identify which type of flare they have, and therefore they cannot specify the proper flare when ordering replacement lines. Nor can most people recognize a potential problem when fitting lines with different (incompatible) flares.

MOPROD, a company that was a major supplier of aftermarket or replacement lines for British cars originally came up with this “Universal Flare”. This design will seal properly when used with any of the four types of unions normally encountered on British Cars.

The diagram below shows how this is possible.
Suffice it to say that the hydraulic lines we supply all come with the “Universal Flare”, even though they are made by several different manufacturers. If your hydraulic cylinder has some damages, have it inspected and fixed by a hydraulic cylinder repair contractor before you decide getting a replacement.

Please note that this universal flare is not the same as the standard American double flare (SAE 45º) used on cars in the US.
