Sweat Fitting Adapter for Potable Water

The Nibco 7032RLF-3412 is a straight adapter designed to connect copper tubing to a female NPT thread in potable water systems. It is intended for plumbers and contractors who need a lead-free bronze transition fitting certified to NSF/ANSI 61 and NSF/ANSI 372 standards.

Installation uses a sweat connection on one end

The cup end accepts 3/4 inch copper tube with a 7/8 inch outer diameter and requires soldering, while the other end provides a 3/4 inch FNPT thread for a threaded joint. Proper flux, heat control, and thread sealant are essential; insufficient cleaning or overheating can cause leaks or joint failure.

Rated for 466 psi at 200 degrees F

The C87850 bronze body meets ASME B16.18 and ISO 9001 requirements, limiting use to the stated pressure and temperature range. It is not suited for applications exceeding these values, for non-potable fluids incompatible with bronze, or for connection types other than sweat-to-FNPT.
