school me on fittings for bags

[Zomgmike]

So I bought a front kit privately and now i could use some schooling on fittings. I plan on running 3/8s line and valves. On the bag the diameter of the port hole is 3/4" but everywhere i look its a 1/2" port. What kind of plumbing setups do you guys run?

They are 2 airlift d2600 bags, oh and can i buy the majority of the fittings at homedepot, or do i need to buy specific fittings off a website that are made specially for air ride?

A lot of guys run DOT air brake line with push to connect fittings to limit air leaks with compression fittings (at least this is what i did) you can also use push connect with hard line if you would like. The best place i found to get fittings if on Airedup.com (http://airedup.com/) They have literally every fitting you need.
