Thrifco Plumbing 8113171 PVC Adapter – 1/2 Inch Male Thread X 1 Inch Slip, SCH 40

This Thrifco Plumbing PVC adapter lets you connect a 1/2-inch male threaded pipe to a 1-inch slip (socket) fitting.

It's SCH 40 rated, so it's standard for plumbing and irrigation projects.

It's brand new and made for non-potable water applications—it contains lead, so don't use it for drinking water.

California residents should note the Prop 65 warning.

But for drainage, irrigation, or other non-potable uses, it's a solid fitting.

The part number is 8113171.

If you need to adapt down from 1-inch slip to 1/2-inch male pipe, this is the piece.
