Copper tee for potable water systems

This cast-copper sweat fitting joins two 1-inch copper tubes with a 1/2-inch female NPT branch. It is intended for installers running potable-water lines who need a durable, lead-free tee that meets plumbing codes.

Sweated joints on the run and threaded branch

The two cup ends accept 1-inch copper tube for soldered connections while the 1/2-inch FNPT outlet accepts standard pipe-thread fittings or valves. This layout lets you add a take-off without extra adapters, keeping the joint count low.

Pre-cleaned surface and center-stop-free bore

The fitting arrives pre-cleaned so flux can be applied immediately, and the open bore avoids flow restriction at the branch. No additional sealants or gaskets are included, so installers supply their own solder, flux and thread tape.

Questions about this item

How does the 1/2" FNPT branch affect flow when the tee runs at full capacity?

The 1/2" FNPT outlet creates a smaller passage than the 1" copper runs, so flow through that branch will be restricted compared with the straight-through ports.

Will the cast copper body stay quiet and cool in a constantly circulating hot-water loop?

Cast copper conducts heat well and has no moving parts, so the fitting itself adds no noise and reaches equilibrium with the water temperature.

What copper tubing must be on hand to sweat the two 1" cup ends?

You need 1" Type K, L, or M copper tube with a 1" outer diameter for the two cup connections.
