Copper fittings are made following the ASME / ANSI B16.22 and B16.24 standards. Copper and cast fittings are produced in the United States and Mexico. These fittings are very cost-effective and highly efficient, therefore, they are used in pipe works for air conditioning devices. They are made from top-notch raw material, an alloy which is either copper or bronze. They are produced in two series, wrought (wrot) copper fittings and cast copper fittings. The copper fittings can withstand a maximum working pressure of 200 PSI and produce in sizes ranging from 1/4” to 8”. They are used in different industries to serve various purposes. |

1. What are Copper Fittings used for?
|
Fittings are used in pipe systems to create a connection between tubes, pipes, and hoses. They are one of the major devices ensuring a smooth flow of liquids and other substances in machines. Fittings are produced in various sizes, shapes, designs, and types to enable them to fit into different industries where they may be needed.
Copper fittings are made from Bronze or Copper alloys following the American Society of Mechanical Engineers standards, B16.22, and B16.24. They are used to connect pipes and tubes (copper) in systems or pipe works. The NIBCO Company which was established in 1904 is a major producer of fittings, valves, etc. The available copper fittings from NIBCO are classified into two series, Wrought Fittings (600 series) and Cast Fittings (700 series). Copper fittings are available in different sizes from ¼” to 8”. |

2. What are NIBCO Copper Fittings made of?
Tee C x C x C – Cast
|
The two series of NIBCO Copper Fittings are made from different materials. Wrought (wrot) copper fittings are made from undiluted copper mill products following the ASTM B75 Alloy C12200. Cast copper fittings are made from Copper Alloy C84400 chemical composition is 3% tin, 7% lead, 9% zinc, and 81% copper. The standard followed for the production of cast copper fittings is the ASTM B584.

3. What does FTG mean in Copper Fittings?
FTG copper fittings mean the piece's sweat end will go into another regular copper fittings end connection like tee or elbow. Wrought (wrot) copper fittings are made from wrought copper. Wrought copper is a name for copper end-product. Wrought copper fittings follow the ASME/ANSI B16.22 standards and are used in pressure systems (wrought copper and copper alloy solder joint). They are made from different alloy types such as C10200, C23000, C12000, and other alloys containing a minimum of 84% copper (Cu) and a maximum of 16% Zinc (Zn).

Further, wrought copper fittings are made following the ASTM B88 seamless copper pipes, and the sizes (standard outer diameter OD) are from 1/4” to 12”. Any nominal pipe sizes correlate ASME/ANSI B1.20.1 standards and the threaded male or female connections.
The fitting marking of wrought copper fittings is following the standards of MSS SP-25. Also, the copper body has the trademark of the company or manufacturer’s name stamped on it. However, this is omitted when the inscription could cause damage to the fitting. In annealed temper, the wrought fittings type M, L, and K seamless copper pipes have a four times burst pressure. The table below shows the standard list for wrought copper fittings: |

Cast copper fittings are made following ASME/ANSI B16.18 specifications (cast copper alloy solder joint pressure fittings), and are applied for solder joint duties. The fittings are produced following either the ASTM B62, alloy C83600 standards or tensile strength and chemical specifications of ASTM B584, alloys C84400 or C83800. The chemical composition of the cast brass fittings is 85% copper (Cu), 5% tin (Tn), 5% lead (Pb), and 5% zinc (Zn).
The sizes of the copper fittings are made to fulfill the specification of seamless copper pipes, ASTM B88. This is for sizes between 1/4” and 12”. Also, the nominal pipe size correlates with female and male connections. The body of the fitting comes with an inscribed trademark on it. Type L seamless copper pipe has an equal or higher burst strength than the general ones. |
Cast bronze threaded fittings classified under class 125 and 250 are produced following the ASME/ANSI B16.15 standards. The fittings may conform to the specifications of ASTM B62, alloy C83600 or tensile strength, and chemical prerequisites of ASTM B584, alloys C83800 or C838400. For smaller-sized fittings like round or hex bushings, wrought plugs, the requirement to be met is according to C32000, C36000 (free cutting brass rod, shapes, and bar), or C31400 (leaded brass) standards.
