Q: What is the difference in supply types? I currently have a Watts Premier and am thinking about replacing it?
A: AquaFX Hose Bib Adapter
Choose either 1/4 or 3/8 inch depending on your tubing size. Tis goes from standard hose bib size thread.
Inline Under Sink Adapter
3/8 Female x 3/8 Male Thread with Quick Connect Fitting for 1/4 inch Tube
Fits into Most Undersink Hoses.
Teflon Tape will assure a good seal
