Installation tips and best practices
- On the compression end, ensure a clean, square cut on the pipe and seat the compression nut and ferrule fully to form a tight seal.
- On the FPT side, apply an appropriate thread sealant or PTFE tape (for metal-to-plastic interfaces) to the male threads before threading in the mating component. Tighten to manufacturer-recommended torque to avoid leaks.
- Do not overtighten: brass threads are strong, but excessive torque can damage fittings or pipe.
- Use this adapter as part of a well-supported piping run to prevent stress on connections, especially where pipes may shift or vibrate.
