A homeowner needs to install a water filter on 70-year-old galvanized pipe but cannot figure out which adapters (IP/NPT) to use with PEX due to conflicting information, incorrect search results, and difficulty working with old threaded joints.

Online search results for 'IP fittings' often show NPT fittings, and there is no easy way to identify the correct adapter for transitioning from old galvanized pipe to PEX without professional knowledge.

It eliminates guesswork and wrong purchases.
