Questions about this item

How does the 395 psi pressure rating translate to everyday plumbing use?

The 395 psi maximum pressure rating provides a substantial safety margin well above typical municipal supply pressures, ensuring reliable performance in standard residential and commercial installations.

What does the C x FNPT connection standard mean for fitting compatibility?

The C x FNPT designation indicates a copper tube sweat connection on one end and a female national pipe thread on the other, allowing direct transition between copper piping and threaded components without additional adapters.

What clearance is required to install this 1-inch bronze trap?

The fitting features a 1-1/8 inch outside diameter on the sweat end and a 1-inch pipe size, requiring sufficient space for soldering the copper joint and threading the FNPT connection during installation.
