The C-434 is kind of an odd hose bibb that might be useful for some that require a specific bibb layout. Key features about the C-434 are that it's a freezeless, anti-siphon bibb with a backflow check valve. The C-434 requires about 2-1/4 360 degree turns to get the valve 100% open where a bibb like the P-164 requires roughly a single quarter turn. The body of the C-434 is 100% brass but with a satin nickel plating which gives an attractive but also durable protective finish. What's nice about Prier products is you can rebuild the internals of the hose bibb making it a true lifetime product!
These C-434 hose bibbs come with a type D seating option which is a 1/2” MIP x 1/2” SWT that requires you to bore a 1” hole. From what we've read MIP is equivalent to NPT.
The C-434 can provide a year round freezeless operation due to the bibb valve being connected to the water supply pipe in the heated section of the structure (Your house or garage). The 4" or 12" are recommended for locations where it gets really cold outside because the valve will be further inside the heated structure where something like the 2.5" close couple bibb has the valve closer to the exterior elements. The copper piping on the prier C-434 hose bibbs are at an angle so any water left in the pipe will drain out through some holes behind the handle when fully closed and not risk being frozen in the pipe.

For Use as a Bucket Filler - Height Recommendation: Remember that the hose will carry a radius when hanging freely. In my wash bay, the bibb is mounted at 45.75" from the floor to the center line of the mounting holes. That leaves the tip of the nozzle at 14.5" from the ground. I would suggest moving the bibb up another 1.5 inches since the Ultimate Nozzle is a bit longer than my old Adam's.
