New air ride manifold arrived a week or 2 ago, from the US. This is there new threaded version, so you can use you own fittings. Meaning you have a choice of air line, not limited to 3/8" dot air line. As there old style manifolds came with 3/8" push to connect fitting, pre fixed and sealed in to the manifold. Down side to this are, you can only use 3/8" air line, and if you damage or have a leaking fitting, you need to send it away to get the fitting re-pressed and sealed in to the unit. With this new type I bought, you can use any fittings you want, so you can run any size or type of airlin
