When running water lines from here


What internal diameter hose should be used?

Cheers

 

-3 for oil, -4 for water.

 

-4 being 4/16ths being 1/4"?
Sorry, I'm from England!

 

I was using AN sizing

 

AN sizing only references the OD though yeah? When really I'm asking for the ID of the hose or the OD of the nipples on the car...

 

I think -4 is 5/16", -3 is 1/4"...that's off the top of my head. I'm positive -6 is 3/8" so I just scaled down. I custom did my lines in all braided with no barbed fittings, so I can only compare.

 

I used 1/4" ID.

 

1/16' = -1AN, so -4 is 1/4", -6 is 3/8", -8 is 1/2", etc. All the way up to -20AN which is 1 1/4".

I've typically used -6AN for water lines, but that's only because M14x1.5 to -4AN fittings can be hard to find. -4AN or -6AN is fine.

 

Mick,

In my experience hose with an 8mm internal diameter is a good fit. I use steel braided hose with crimped banjo connectors on one end and and hose clamps on the other.

 

Hmmm I never even thought about what size my lines were... I got Artech's SS oil/water lines. Anyone know off hand what size these are?
