Are you looking for a 1/2" hose fitting with a rubber grommet that sits flush inside your custom intake tube?  Well look no further as this is exactly what you need.

I have scoured the internet, looking for this exact kind of fitting.  I found fittings that were exactly what I was looking for but was not the right size I needed to connect the OEM vacuum tube into my custom intake tube.  I decided to just say screw it and make my own kit.

Fitting is 3D printed from Acrylonitrile Styrene Acrylate (or ASA) filament inside an enclosed and heated chamber for best layer adhesion.  Grommet is just a normal rubber grommet meant for hydroponic gardens.

INSTALL:

Grommet requires a 7/8" hole for install.  Soapy water recommended when sliding the fitting into the tube and into the grommet.
