Our stainless braid conductive teflon hoses are among the highest quality hoses that exist.  These hoses are impervious to all types of fuel without having to worry about hose integrity.  In addition, our -4, -6 and -8 hoses, have a .030 thick layer of carbon black manufactured into the hose which provides an electrical path to the fittings on the end.  Essentially, the conductive teflon hose is able to dissipate static electricity buildup that can exist when fuel flows through a hose.  This is something that is found on high end certified aircraft hoses.  We feel it is important, because it adds an extra margin of safety to your aircraft, and also prevents static discharges from eventually creating little pinholes in the hose.

Please note that our -3 hoses are not conductive teflon, because there is not enough fluid flow through them to warrant the dissipation of static electricity.  They are typically used as primer lines in aircraft or as brake lines on cars.  For aircraft we recommend -4 hoses for brake lines to mate with the typical -4 hard lines that are used in the cabin.

Finally, our hoses are covered on the outside with a stainless braid wire.  The rated bursting pressure on these hoses is between 8,000 and 12,000 PSI depending on the diameter.  Working pressure is between 2,000 and 3,000 PSI, and we test all hoses to their rated working pressure before they leave our shop to give you peace of mind.  This is something that not all manufacturers do, as it is time consuming.  However, we recognize that these hoses are the lifeblood of your aircraft, and so we check each and every one before it leaves.

For planning purposes, the minimum recommended Bend Radius for our hoses are as follows:

-3 Hose (2 inches) / –4 Hose (2 inches) / -6 Hose (4 inches) / -8 Hose (5.25 inches)
