Overview

Nylo-Seal tube fittings are exceptionally strong. The bodies, made of nylon, are stronger than machined fittings of similar composition. They are furnished complete with nut/sleeve assemblies, made of acetal copolymer. Since the sleeve snaps into and is retained by the nut there is no fumbling for a loose sleeve. Just insert tube into the fitting and tighten the nut 2 to 2-1/2 full turns. Note: The most frequently used combination of tube and pipe sizes are 1/4" Tube x 1/8" Pipe and 3/8" Tube x1/4" Pipe.

For Nylo-Seal tubing, see "Accessories" tab

As described / expected. The only thing I would like to see that wasnt included would be the small inserts that support the ends of the inside diameter of the tubes.

Q: I assume since these are pipe thread that no pipe dope or tape is needed (or desired) on the threads, right?

One end is pipe thread, and will seal without teflon tape or compound.

Q: Which tap would I use for 268-no6x04?

You would need a tap for 1/8th NPT.

Q: What is the difference between this part which is part number 268-N04X02 and another fitting which is part number 12-05471

They are just from different manufacturers, they will both work with nyloseal.

Q: Will NYLO-SEAL FITTING 268-N04X02 screw into standard Altimeter, VSI, and Airspeed indicators at its input

If those instruments have 1/8 npt ports on them yes. That is the most common size.
