Oil Catch Can sizes

Hey Guys,
So I'm looking at catch cans for my Ka24de. The PCV valve on the block is 9mm hose, but most fitting on catch cans I see is 15mm. What do you guys do to get around that? I figured I could just change the fittings, but most of these manufacturers don't list what the fitting sizes are.
Thanks for your help!

I switched mine to -8AN (Which is 1/2 hose if you're not familiar)

I tapped the valve cover to 3/8NPT and ran a 90* 3/8NPT to -8AN fitting, and on the PCV I believe its already 3/8NPT, so just used another adapter fitting.

My catch can is a vented can from www.racecatchcan.com , if you get in touch with them, they'll make about anything you want.

That's awesome I love that idea. Where did you get your fittings from? Anyone on here know what size thread Greddy uses on their catch cans? I have one with a 15mm barb but don't know what the thread size is to replace it if I go with the AN fittings.

I've ordered my fittings from all over the place. siliconeintakes.com has some decent ones for good prices, i've also used vibrant as well.

word thanks! Out of curiousity, did you run a check valve in line once you ditched the pcv?

I did not. I don't see a reason too. Start the car and put your hand over that line and tell me if you think its possible for something to get sucked back in. That thing moves some air.

Considering mine is hooked to a vented can (which we will call it sealed, as nothing is technically exposed to the elements) nothing that could harm the engine could get in it anyways.
