- Potable-water compatible installations where lead-free brass is preferred, backed by traditional reliability of MNPT threads
Installation basics for dependable seals
- Apply an appropriate thread sealant or PTFE tape compatible with metal piping to both ends
- Clean threads before assembly to ensure a secure, leak-free connection
- Tighten gradually to the recommended snug fit—avoid overtightening to prevent thread damage
