Pipe size is an industry designation, not the actual size. View information about how to measure threaded and unthreaded pipe and pipe fittings.
More
Combine an adapter with a two-piece pipe flange (sold separately) to build a customized flange connection. Also known as Code 61 or Code 62 split flanges, the two halves of the flange clamp around the adapter and bolt to another Code 61 or Code 62 flange. Flanges and adapters should be used in noncorrosive environments.
NPTF (Dryseal) threads are compatible with NPT threads. UN/UNF (SAE) threads are also known as O-ring boss threads; they have a gasket to prevent leaks.

Combine an adapter with a two-piece pipe flange (sold separately) to build a customized flange connection. Also known as Code 61 or Code 62 split flanges, the two halves of the flange clamp around the adapter and bolt to another Code 61 or Code 62 flange. Flanges and adapters are 316 stainless steel which has excellent corrosion resistance.
NPTF (Dryseal) threads are compatible with NPT threads. UN/UNF (SAE) threads are also known as O-ring boss threads; they have a gasket to prevent leaks.
