All of the advantages found in copper as a metal have been capitalized to the utmost in the manufacture of NIBCO
®
Fittings. Because
of the accuracy of construc tion and design, copper plumbing is more efficient and less expensive.
NIBCO manufactures nine general types of fittings: Wrot Pressure; Cast Pressure; Wrot Drainage; Cast Drainage; Flanges; Flared
Tube; Threaded Bronze; Insert Fittings for PEX; Barbed Insert Fittings for Polybutylene. Each has its particular place and use and each
offers its own advantages when used for the proper service requirement.
Material & Construction — NIBCO Fittings are made from the highest quality raw materials — Cast Fittings are offered in traditional
copper alloys C83600, and C84400 and high quality lead-free* dezincification-resistant (DZR) silicon bronze alloy C87850 cast or
69300 forged Performance Bronze™ per ASTM Specification B584. Wrot Copper Fittings are made from commercially pure copper mill
products already meeting current lead-free* requirements per ASTM Specifications B75 Alloy C12200.
Lead Free refers to the wetted surface of pipe, fittings and fixtures in potable water systems that have a weighted average lead
content ≤ 0.25%.
NIBCO Fittings are produced to meet the requirements of applicable standards.
The majority of NIBCO
®
brand wrot and cast fittings are manufactured in the U.S.A. and Mexico*. The manufacturing plants at
Stuarts Draft, VA, Nacogdoches, TX and Reynosa, Mexico are registered to ISO 9001 quality standards.
