WHEN LAST WE SPOKE of these, all I was aware the manufacturer made was pipe fittings — asses and elbows and sleeves: Oh, my! Just the stuff to fit between ends of pipe or tubes — cut square and cleaned of all burrs, etc.
We am pleased to note that the manufacturer — Shark Bite — has expanded their line. This is a half-inch to three-eighths, straight, quarter-turn stop supply valve. It does not need sweating. It can be used for toilet and sink shutoffs. This is, as they say, the greatest thing since the greatest thing since sliced bread.
In what appears to be a Stupid Legislator Trick, it is illegal to sell this product in California and Vermont.
