That's the concern. If it's 10psi at room temp, what can it handle in the engine bay? It gets HOT in there. I'd rather do it right the frist time.

Oh, and "Crush-Resistant White Silicone Rubber Tubing" on that same page is semi-clear white and rated to 35 psi. (the other stuff is rated to like 150 psi haha)

It doesn't look like the majority of those that Mcmaster sells are fuel and oil safe.

That's an industrial rating.

Meaning you can run fuel and oil through them at pressure 24/7. Silicone is silicone. It's not going to degrade from the oil and fuel residue your PCV system will have in it.

McMaster rates their stuff based on the certified industrial ratings, ISO and OSHA and all those other agencies and organizations. Don't take them too literally for our hobby work, a large majority of the aftermarket parts people out there are using these same components and charging 2-3 x's as much and just leaving off their official ratings info.

You're right. I doubt it would see the concentrations required to degrade the hose, but better safe than sorry.

I agree, but I'm telling you, the silicone tubing that everyone uses for automotive stuff would be rated the exact same on those scales. It's just that no one is telling you that it'll degrade if you put 50 psi of gasoline through it for a year, even though it definitely will.

Anyway, post up what you end up going with!

Chuck33079 · 06-13-2013, 11:27 AM

I'll probably end up with something like this -
Silbrade® Braid Reinforced Silicone Tubing | U.S. Plastic Corp.

It's complete overkill, but I'm partial to overkill.

Sh0velMan · 06-13-2013, 11:35 AM

Dude, that's exactly the same stuff that I linked lol

Chuck33079 · 06-13-2013, 11:41 AM

You're right. I was looking at the Crush-Resistant White Silicone Rubber Tubing, not the High=pressure with the braid. Doh.

... Color is meh.

Note: I like to flush them out with some brake cleaner, just wipe it off of the exterior pretty quick, dunno how the finish will like brake cleaner. You can use isopropyl alcohol if you prefer to play it safe.

The cans are billet aluminum, so if you prefer that color to the yellow just go to town with the brake cleaner.

Great DIY!

Haha, they're definitely not billet aluminum!

Looks like aluminum tube with end caps epoxied on, actually. Like I said, they're stupid cheap and functional. :P

Good point though, I could totally strip that paint off and paint them something else... I honestly never thought of it... sad, I know!

I will be definitely doing this soon. Great write up. Thanks

Sh0velMan · 09-27-2013, 10:26 PM

Bumped for new photo and info.

Nut_N_Much · 04-18-2014, 10:15 AM

Good job, doing mine now, got my cans and tubing yesterday.. Great DIY.. +1 Rep....

Jordo! · 04-18-2014, 10:25 AM

Are the slotted pipes intended to act as a filter so it's not just blow through?

It's pricer, but I also saw a filtered Jegs separator on there too as another option.

Nice DIY -- thanks!
