AN Aluminum crush washers for oil cooler install?

[absolute_DSM]

I know I need to use aluminum crush washers for a few of my my AN adapters. (Just like a bulkhead to the fuel tank with nuts)

Now Ive been looking around for some 18mm and 16mm with no luck whatsoever. (Oil cooler and fuel rail) ANplumbing couldnt even get them and theyve always supplied all my AN needs.

So what are you guys using?? Ive looked at some install pics and cant tell if people are just not using them or maybe using o-rings? I was told by ANplumbing if I didnt use them, I would leak and I very much believe them.

What fittings are you using that require crush washers?
Show me.

Oil cooler should be the common 14mm ones. Same as for the turbo water lines.

If youre talking about the copper crush washers for the banjo bolts, I dont see how they could be 14mm when the banjo bolt is a M16x1.5. Explain? Plus those are copper, from what I was told I need aluminum.

I do see the washers. That is a possibility. I wasnt sure if that type of crush washer/o ring would suffice. Good to know. Maybe Ill call and see what size they are using. I have another order from Summitracing going in so maybe I can throw them in that order.

Paul see the pics attached.
Youll notice the so common oil cooler fittings (1g oil cooler) and my fuel rail setup. The washer on the fuel rail is a 3/4" ID. The only reason it fits is the adapter is a Earls piece so the collar is bigger. If that makes sense?
I used the crush washers on the clutch line I made up and Ill be using them on the tank for my -6an bulkhead fitting from the pump.

Thanks for the replies guys, sometimes I over think things, but a leak from the oil cooler or my fuel rail would make this guy not very happy when I go to finally start this thing.

Mine all use O-rings.
The only place I'm using crush washers is banjo fittings.

Thats what I wanted to hear. I order all my ANs from ANplumbing and they said without the aluminum washers I would leak. Ill call and see what they say about o rings.

No leaks then I assume?

What size o rings do you use for your metric fittings then?

 

[gsx951]

I have a viton o-ring kit at work and never pay attention to sizes. I just grab what seems to fit-sorry.
My oil cooler has been together for years and even with an unported filter housing and 100psi+ pressure, there were no leaks.

 

[absolute_DSM]

Awesome, that really puts me at ease. I should be able to go into a part store now with my ANs and just grab what fits.

Man I feel a lot better Thanks

For my oil cooler this is what came with my kit, I can't recall if it was the -6an set specifically that went around the M16 x 1.5 or if it was some other inside diameter but this was what was included with the kit.

FYI: The Stat-O-Seals on that ANplumbing link above work well also. I've used them on my motorcycle and have had no issues.

 

[absolute_DSM]

Yea, if I have any issues with the o rings I am definately going with the stat o seals.

Thanks guys.
