There's a Permatex version of 567 that you should be able to find a cross-reference table for in order to identify the exact number.

Anyone have any experience with a Loctite 567 alternative that I can buy locally? |

Napa, Advanced Auto and similar places have this under one name or another.

From the Parker site (manufacturer of our wheels), suggests permatex 56750 is an equivalent to Loctite 567.

I was very careful about this when installing the oil cooler fitting in the engine case. It won't get as tight as you think, based on plumbing experience. AND . . . this is a 1/8" NPT fitting.
Funny story, my Dad frequently worked on equipment (off road) and is line was "tighten it until it squeaks" . I had some guys who did that with a 3/4" air impact on some wheel nuts on an articulated truck. The wheel fell off! The 3/4" impact only went to 250 ft-lbs (longer story), and the nuts needed 360 ft-lbs. Lesson - never assume.

Any chance we could get a picture of you torqueing those master cyl fittings to "spec" on a completed aircraft

Measure the depth of the tapped hole and tape the measurement on the fitting so you can see if the fitting is going to bottom out. You might need to file the fitting.
This size fitting should not require EXCESSIVE force.

Teflon Paste

One of the major reasons for not using Teflon tape is that it may brake off and clog a opening in an aircraft line. Similar to what might happen with Fuel Lube. But why wouldn't a gob of any thread paste pushed into the end of a fitting do the same thing? Can't see the difference in using Teflon tape or Teflon paste.
