Installation tips
- Prepare the 3/4 in. copper pipe with a clean, deburred cut. Apply flux and solder the copper sweat end per standard copper-sweat techniques to form a secure joint.
- On the 1 in. FIP end, wrap the threads with PTFE thread seal tape in the direction of tightening, or use an appropriate thread sealant. Tighten evenly to seal without over-torquing.
- Always verify the joint for leaks after assembly and pressurize gradually to ensure a dependable connection in both new builds and repairs.
