3/8 Hardline to 1/4 NPT male Compression DOT fitting – SqueakyCleanAir

Best priced fitting to get the job done.  These may not be as fancy as the silver based Swagelok or other replica fittings out there, but these are rated to 350PSI which is pretty substantial considering most air systems will only usually get to 250PSI or less.  Never leak and not the cheap kind as well.  We love to us
