ASF has custom hose ends that allow us to install different sizes on each end of the same hose.  These can be found on drop down menus on the -3 and -4 hose assemblies.  

Currently available ends include

1. -3 hose can utilize -2 or -3 str/45/90 hose ends. We can also install -2 str/45/90 Primer ball hose ends on -3 hose.  This allows us to mix and match.  As an example, a -3 hose could have a -2 AN fitting on one side and a -3 AN on the other.  Or, a -2 primer ball on one side, and a -4 AN on the other.  This allows you to adapt the hose ends, versus changing out fitting configurations on your aircraft or engine.

2. -4 Hose assemblies can utilize -4 or -6 str/45/90 degree AN hose ends.  

3. All hose ends are made of stainless are are one piece (not soldered together as in case of most currently available primer ball setups)  Nuts on -2 AN assemblies are aluminum and nuts on -2 primer balls are standard Brass.

THESE OPTIONS ARE SELECTABLE FROM DROP DOWN MENUS ON THE HOSE ORDERING PAGE.
