0.25 (1/4) OD Blue Polyethylene Tubing

Doesn’t work as advertised to reduce tds to 0. Customer support was unresponsive.

Outstanding quality! Works well.

So far so good. Fast shipping. Which ya had more fittings to tap into water lines besides a fawcet. My fawcet over pressured from r.o.membrane and stained a ceiling. Ugh. Thanks

Works as described for my saltwater mixing station.
