I still have one more place to try, will post up if any success.
As for ordering bulk on fittings, i don't see the need as its just as easy to buy the common ones locally. With the regulators, the HI sides are LHT, while the low sides are RHT...both 1/4...so same as air fittings(hardware stores, PA, etc).....but the high sides are LHT 1/4, which is rare cause very few applications use LHT, except some propane...can't remember what else.
When i built my manifold, i just used all compressed air parts from PA.....the manifold, the barbs, lines, and hose clamps from there were reasonably priced......now if bought at HD or other hardware stores, you're looking at double your price from what i've seen with their prices.
