7N Female NPT Fitting

Description:

The 7N fitting has female NPT threads at both ends to join two male NPT connections in a straight layout. Equal-size models connect matching thread sizes, while reducing models connect different sizes.

Those female NPT fittings can make a strong seal between pipes and fittings.

If you have any questions about the npt pipe fittings, feel free to ask.

Features and Benefits:

Female NPT Connections: Internal tapered threads at both ends connect mating male NPT components.
Straight Body: Joins two connections in line without adding an elbow.
Equal and Reducing Configurations: Choose matching or different thread sizes for the required connection layout.
Hexagonal Wrench Flats: Provide tool engagement for holding the fitting during assembly.
