5 PCS 1 Inch Copper Male Adapter C x MNPT LF Plumbing Fitting Sweat Solder

About this item

Tying 1-inch copper into a threaded pump, valve body or tank fitting calls for a 1 inch copper male adapter C x MNPT. This lot includes five, listed as new and lead free (LF), with a solder cup on one end and male pipe threads on the other.

Is a C x MNPT adapter soldered or threaded?

Both. The cup end is sweat-soldered onto 1-inch copper tube; the MNPT end threads into a 1-inch female fitting.

• Order of work: solder and cool the joint before applying thread sealant.
• Backing up: hold the adapter with a wrench while tightening so the solder joint isn't stressed.
• Mains and trunks: 1-inch is common on service entries and large supply runs.
• Permits: water service work often needs a permit; check locally.
