What kind of length(s) are you looking for and do you want connectors on the end?

Many of the RG-400 coax are made in China, there are some US based companies like Harbour Industries etc that specialize in Teflon based coaxial cables but they are going to be more expensive then the asian made cables.

If you do not care if it came from china have a look at:

Another Teflon based coax similar to 50-ohm RG-142 and 75-ohm RG-179 is 75-ohm RG-187.

Is there a 75 ohm equivalent to RG400 coax?

Not that I know of, although are there's at least one sort of like RG142. KZ1W sent me several miniature coaxes to evaluate for chokes for TX 4-squares, the most useful of which seems to be RG179. It's addressed in the Cookbook.
