Brass PEX Male Sweat Adapter
No room in the joist bay for a stub of copper? That's exactly the job of the brass PEX × male sweat street adapter. Its copper end is sized like 1/2″ pipe itself, so it solders directly inside an existing elbow, tee, or coupling — no jumper, one less solder joint, an inch of space saved where there wasn't an inch to spare. The other end is a 1/2″ ASTM F1807 barb that crimps to PEX with a standard copper ring or stainless steel pinch clamp once the soldered side has cooled. Machined from lead-free brass, cUPC certified and rated to NSF/ANSI 61, it makes the copper-to-PEX handoff exactly where the old system already branches. The order never changes: solder first, let it cool, then crimp — the barb never sees the torch. Sold as a single for the service call or a 50-pack for the van that lives in retrofit country.
Features
- Street (FTG) design — male sweat end fits inside copper elbows, tees, and couplings, no pipe stub needed

- 1/2″ F1807 crimp barb — seals with copper crimp rings or stainless steel pinch clamps

- Torch-then-crimp install — solder the street end first, let it cool, then crimp the PEX
- Single or 50-pack — one for the service call, a contractor bag for retrofit crews
