Hey guys, I know a lot of us are running some sort of oil catch can in our Z. My question is what kind of rubber hose are you guys using?

I got the Greddy catch can and the hose that come with it gets kind of soft and some section of the hose become pinched under the heat and pressure. You can also hear some whistling noise after driving the car for a while.

Then I switch to GoodYear fuel injector hose, it seems to be stronger...but it still become pinched (not as much compared to Greddy hose) from the heat and pressure.

So, I just want to know if these are better rubber hose out there that would work better....or.....this is normal for using rubber hose?

Thanks

 

c'mon, some one gotta know.....

 

I went online to JEG'S and got some quality braided line and it has worked so far.

 

thanks.

I went to the site but the measure is in AN, how do you convert it to mm?

 

Just go pick up some braided line at a speed shop.

9mm braided is what I used on mine instead of the garden hose crap that came with the can.

 

Samco hose on mine

 

I used to use this silicone hose with internal support but it collapsed. My cousin gave me a fuel line i think and its holding up well.

 

Yeah, wtf is an AN anyway??

 

I had some rubber hose on mine and when the engine bay got warm it lost its rigidness and got kinked. I changed to braided stainless lines for ~$20 and it works perfectly.

 

 

from JEGS website - the length is in feet, but the diameter is AN

"Compatible with all synthetic lubricants, fuels, oils, coolants, and alcohols (including methanol), this hose was developed to meet strict racing specifications. It's available in -4, -6, -8, -10, -12 AN and -16 AN in lengths of 3, 6, 10, 15, and 20 feet. The hose is constructed from a seamless nitrile inner tube with a stainless steel inner braid and high-tensile stainless steel outer shell to resist high pressure, temperature, and abrasion for reliability at a price you can afford. NHRA accepted."

 

Don't use teh home depot clear tubing that it comes w/...that shiz heats up and totally collapses.

 

AN stands for "Air Force-Navy Aeronautical Standard" and was an aviation fitting standard developed around WWII

 

To expand on that......

The AN size standard nomenclature goes by 1/16" of an inch. It measures the inner diamter of the AN hose. So a -3 AN is 3/16" of an inch. -4 AN is 4/16" aka 1/4".

And it is pronounced "Dash 3, A, N."

Don't walk up to the parts counter like a noob and say I need "Negative 3, an." LOL

Fuel line or heater hose are both good alternatives to the fountain drink machine hose that's become "JDM" style. If you are getting kink's in your hose you're trying to bend too small of a radius into the hose. Find a way to route the hose better so it doesn't kink.

 

i used 3/8" fuel line hose. works perfect

 

^ yes, probably the best and cheapest way. Braided stainless looks great and works perfect just a bit more expensive.

 

Sooooo, that is equal to a -6 AN???

 

+1

It is a hard(ish) rubber hose with the cloth reinforcing or whatever in the rubber. Hasn't collapsed, and hard to squeeze shut with your fingers as well..


Sorry about the stupidity... just woke up.

 

Not exactly the same size. -6 AN is close to 5/16" I.D. whereas -8 AN is closer to 3/8" I.D. hose. PCV system hose is another alternative is made for oil vapor usage and is strong enough to not collapse unless it gets kinked.

 

Sounds like fuel injection hose, it's pretty sturdy stuff.
