Hose Assembly Instructions - Type 811 and Type 910 Hose

Hose Assembly Instructions - Type 811 and Type 910 Hose

Using Bent Tube Style or Forged Black and Silver Anodized Hose Ends

Super-Flex Braided PTFE Fuel/Oil Hose & AN Hose Ends

If you are used to using traditional red-and-blue AN hose ends with rubber-lined stainless braided hose, the first thing you might notice is that the silver collar on these fittings will slip right off of the black body.

This is normal!

Unlike those old-fashioned hose ends, the two pieces on these hose ends do not screw together. In fact, they won't even touch until assembly is almost complete.

The silver collar is designed to be a slightly loose fit over the hose. It's really only there to give you a hex for the final tightening step. The black inner portion will actually thread itself into the rigid PTFE liner as you install it. (The silver collar is technically also designed to hold the hose tight against the inner portion at this point, but it will be loose when you first put it on the hose.)

Type 811 Hose End Assembly - Step 1
Step 1

Cut the hose squarely to length using a Cut-off Machine or a very fine tooth hacksaw. To minimize braid flare out, wrap Type 910 Aramid Braided Hose with low-tack blue painter's tape or wrap Type 811 Stainless Braided Hose with glass filament strapping tape. Do not remove tape until ready for step 2.

Step 2

Remove tape and then quickly insert hose into the socket. Insert hose with a turning motion, feeding the braid in as you turn the hose. Koul Tools aren't needed on these easy-to-install hose ends.
