Reducing Coupling 2" x 3/4" FNPT

This malleable iron reducing coupling connects a 2-inch female NPT pipe to a 3/4-inch female NPT pipe. It is rated for Class 300 service and carries the ZORO SELECT brand. The fitting is supplied new and ready for installation in compatible piping systems.

Class 300 pressure rating limits

Class 300 defines the maximum allowable working pressure for this malleable iron fitting at standard temperatures. Thread engagement follows NPT standards with 11 threads per inch on the 2-inch end and 14 threads per inch on the 3/4-inch end. Exceeding the class rating or misaligning threads can compromise the joint integrity.

Connects 2" and 3/4" NPT pipes

The coupling comfortably handles the transition between these two nominal pipe sizes in Class 300 applications. It runs out of headroom when system pressure exceeds the Class 300 rating or when piping requires a different thread standard or size combination not matching the 2-inch by 3/4-inch FNPT configuration.

Questions about this item

How do I choose the right reducing coupling for my pipe sizes?

This coupling connects a 2-inch female NPT thread to a 3/4-inch female NPT thread. Verify both pipe ends match these exact sizes and thread types before ordering.

What does Class 300 mean for pressure handling in my system?

Class 300 designates the malleable iron fitting for higher-pressure service up to its rated working pressure at standard temperatures.

How do the 11-1/2 and 14 threads per inch affect the seal?

The 2-inch side uses 11-1/2 threads per inch and the 3/4-inch side uses 14 threads per inch, both NPT taper threads that seal when tightened with sealant.
