Thread: Metric brass fittings?

Hey all,

I'm trying to install my profec b and it seems the brass nipples they supply are too big. The vacumm hose it came with will fit on them fine, but its fairly lose on the wastegate actuator the nipple on the compressor housing...I've been looking for some metric ones that are smaller so I can use smaller vacumm line but Home Depot, Autozone, and Napa don't have any.

I think it was M10x1.00.

So you're trying to change the fitting on the profec b? That might be a challenge to find. I'd either try to find a matching barb and install another boost source, or you can run down to Kragen, Autozone, etc., and pick up one of those grab bags of vacuum connectors. The one that I have has a whole bunch of T's and straight fittings that I'll never use, but there were some straight connectors and T's that allow different size hoses to be matched up. You could probably find one that will accept the hose from both the wastegate actuator and the profec b...
