Order your Conductive Teflon Hose assembly
Please select your correct diameter hose.  The hose diameter is determined by the
    type of fitting the hose interfaces with.  A -3 diameter hose will interface with
    an AN3 fitting (Ex. 816-3D).  A -4 diameter hose will interface with an AN4 fitting,
    etc…..  Below is an easy way to determine what size your existing hose is.  Place
    a wrench on the Nut on the hose.  
Wrench Size 3/8= -2
Wrench Size 7/16 (Straight) 1/2 (Angled Fittings) = -3
Wrench Size 9/16 = -4
Wrench Size 11/16 = -6
Wrench Size 7/8 = -8

Jump size fittings-  If you have a -3 or a -4 hose and need to “upsize” your fitting
    on one end, we have available the option to build a -3 hose with a -4 str/45/90 fitting
    on one end.  We can do the same with a -4 hose that requires a -6 size “Jump” fittings.
