Our Fittings

OUR FITTINGS

Our fittings are another place that differentiate us from the competition. We use stainless steel fittings on our hoses that are built to Milspec with Class 3 Rolled threads.  Many other manufacturers utilize Aluminum, Corrosion resistant Steel or Brass with a coating that is made to look like stainless.

Stainless steel fittings have two distinct advantages.  First off, they are much stronger than the same size aluminum fitting.  Secondly, in the unlikely event of a fire, aluminum has a much lower melting point. The stainless fittings will protect against the fire much better. This will give you extra time to manage the situation without having a breached fitting that will dump extra fuel onto the fire.

The final item to be aware of is flare angle. Our fittings are all true 37 Degree flare fittings. This means that they are designed to mate with the AN fittings that are used in your aircraft. Some automotive hose manufacturers that do experimental aircraft hoses use a different flare angle.  If you tighten them enough, they will seal, but it is not the correct way to build an aircraft hose.
