Brass Coupling for 3 in NPT Systems

This brass coupling connects two 3 in Female NPT threaded pipes in a straight run. It is rated for Class 125 service with a maximum operating pressure of 200 psi. The fitting suits plumbing installations that require a durable, corrosion-resistant joint.

Threaded NPT Limits and Pressure Class

The National Pipe Taper thread seal relies on thread engagement and sealant, so the joint must be assembled to the correct torque to prevent leaks. Class 125 defines the pressure-temperature envelope for this casting, and the 200 psi rating applies only within that envelope. Exceeding the class pressure or temperature range compromises the fitting integrity.

California Proposition 65 Chemical Notice

This product contains a chemical known to the State of California to cause cancer and birth defects or other reproductive harm. The warning is required by Proposition 65 and applies to the brass material used in the coupling. Buyers who require components without Proposition 65 listed substances should select an alternative material.
