ADD W1 Aluminum Hose Clamps

[Uzurk]

Has anyone used these with their ADD W1 V3.3 catch cans?

Z Oil Catch Can Parts - Aluminum Hose Clamps for V3,V3.3

If so, how has it been so far? Any issues?

 

[RUFFSTUFF]

I have them and no issues so far.

Oh great. I was a little nervous when I saw there was a single screw clamping down both hoses, but now that have one can installed (I ran out of light last night) they seem very solid. Thanks for the reply!

huh... those are typical hose separators, used to organize the routing of hoses. They're not designed for, and can't, apply clamping force to make a seal.
That said, for this application, it doesn't matter. As long as the fitting has some good barbs and they're the right size for the hose, you don't actually need much of a clamp for a ventilation connection.
Just never, ever, do this for something under pressure.

So this is what I meant when I was nervous to use these. Its my understanding that these catch cans do have some amount of pressure flowing through them, so that was the part that made me hesitant to use these clamps. Sounds like I should be in the clear though?

Not pressure _ vacuum!

Ah, gotcha. I am not the most mechanically inclined, so thank you for correcting me. Sounds like that's why these clamps are okay in this application?

Pressure is vacuum! Vacuum is pressure!
It's all relative!

Anyway, there's flow through there, sure, but the pressure differential across the ports on the can should be zero. At most, the can and its hoses might experience 15"Hg vacuum from atmospheric. Which, as long as there are barbs on those fittings, is super easy to seal. Atmospheric pressure is trying to force its way into the hose, but it's also pushing on the hose forcing it to seal. A bit.

A pressure in a hose over, say, 10-20 PSI on a connection like that would need a real clamp to seal. Here the pressure is going the other way and forcing the hose to expand, thus leaking.
