Replacement valve for NRS Float Bags. This is is a twist valve that will fit a variety of float bags (NRS and Harmony).

No adhesive necessary. Use heat to soften 1/2" plastic tubing when removing old valve and installing new valve.

Fits onto 1/2" and 3/8" diameter tubing - NRS bags have a 1/2" tube; the manufacturer's specs say the valve works with 1/2". Can also work with either 3/8" or 1/2" diameter tubing - the difference between fitting the valve into, or over, the end of the tube.
