AMMRL: Liquid Nitrogen Transfer - Use PTFE

I've been using the same PTFE hose (non reinforced) for 7 years. The only
thing I've had to do is trim the ends where the tube slides onto the fill
port. This will eventually start to leak due to the tube sliding on and
off the fill port. I'd strongly recommend others use the Teflon tubing.
You can use short pieces of the Teflon along with a metal coupler to
attach to the tank and metal pipe elbows to get the right tube orientation
to reach the fill port.
