Nibco Inc W00785C 1 Inch Cxc Copper Coupling Roll Stop

Product Description

The NIBCO INC W00785C is a 1-inch copper coupling with roll stop, designed for use in residential and commercial plumbing systems where two lengths of copper tube must be joined with a secure, leak-tight solder connection. The fitting features solder cups on both ends and an internal rolled stop that positions each tube length consistently for uniform solder penetration. Its lead-free construction meets current safe drinking water requirements, making it suitable for potable water applications. Licensed plumbers and pipefitters are the primary installers of this fitting type.

This coupling is used in 1-inch CxC (copper-by-copper) sweat configurations across a wide range of plumbing installations, including domestic water supply lines, hydronic heating distribution piping, and general fluid-handling systems. The roll stop ensures repeatable tube insertion depth on both sides, reducing the risk of improper joint preparation in production or service work. It is sold in a package quantity of 10 units, making it practical for both single-job use and stocking inventory.
