How many of you racers and mechanics, shade tree or pro, have used
AQP Socketless hose for fuel/oil/coolant lines?  What do you think of
this stuff for airplanes?

If you are talking about the blue stuff, it is all I use. I have a mile of it in the race car.

It is Kevlar reinforced. If you must, just a 1/4" hose clamp close the the fitting. I use dash 12 for oil pressureized lines and one dash 10 for a breather hose.

 

We had a failure a few years back when a plug wire got tie wraped to a hose. The electrons soon discovered that the hose is conductive and burned a pinhole in it. When I cut through the pinhole the hose was rock hard in that area.

 

I run 100 PSI oil pressure 100% of the time. No problems in 7 years.

 

It is easy to cut, so care must be taken. In the field it can be assembled by hand if you are a very strong person. I cheat a bit with some grease on the barbs and inside the hose.

You can repair a failure by cutting through it and inserting a length of anything (tubing) that seems to fit tight in the hose. Then add a few clamps to each side of the failure point.

 

It is also the lightest system available. You can twist an end fitting after assembly to improve an installation, and it won't leak. You cannot remove an end fitting without cutting the hose off. The fittings are 100% reusable.
