i can get the rebuild kits for you for the viair. as for the york onboardair.com sells the tube o fittings for the ports that stick up out of the compressor, if you have the flat kind of york i can get you the fittings for those. also i have heard of people just running a 1/2 inch npt tape in side of the fittings that stick up on those kind and just tapping the inside out rather than buying the tube o fittings.
