Figure-8 Closure for Mainline Supply Tubing
Use this figure-8 closure to inexpensively terminate 1/2" mainline supply tubing. Feed a few inches of tub through one hole, then kink the supply tubing and force the figure-8 over both sections of tubing. Forms a watertight seal (see photo).
This is a less expensive alternative to the Direct-Loc style End Cap. It seals, but that is it.
