Skullworks thread pitch

Post by katdime »

Sup fellas? I did a search and came up with nothing on what the thread pitch is to the center holes on the unit. I took it to my local speed shop to get the fitting for it and nothing in there standard sizes fit. My shop believes they are metric. But they don't carry many metric fitting to test fit them. Either way any help would be greatly appreciated. Im also confused as to some say the unit is supposed to run -8 fittings? Not sure if this is there Gen 1 or the Gen 2 before they stopped making them. Here's some photos. it did come with the center o-rings and if you need replacements, I read on line that they used Viton o-rings. Not sure on the size but they sell a box with different sizes online. Im sure you can find the right size for it if anyone is having that issue. Thanks again.

No idea what the thread pitch is. It should have come with 2 fittings for the 2 center ports to connect to -8 AN lines.

Thats good to know. So it runs a -8 with o-ring to seal. But I still need the thread pitch. I knows its not standard. Has to be metric. None of the -8 fitting we tried worked.

I tried the -10 AN fitting none would work. I will make my way back there and try the -8. Thanks for all the part numbers. Not planning on running a cooler but If I do I got part numbers now. Thanks
