​
Material:
Wrought fittings are made from pure copper mill products according to ASTM B75 Alloy C12200. For cast fittings, it is made from Copper Alloy C84400 that consists of 81% copper, 7% lead, 3% tin, and 9% zinc which according to ASTM B54. 

Size Range & Pressure Rating:
The most used sizes for copper fittings are ranged from 1/8" to 8". Copper fittings can withstand working pressure up to 200 PSI. 

Connection Type:
There are three common joint types for copper fittings: brazing, soldering, and threaded. Brazing is a joining process by heating and melting the filler to bonds between fittings and tube. Compare to brazing, soldering is a slightly low temperature heating and melting process that carried out to bonds fittings and tube. Flux is often consumed during brazing or soldering process. It is to clean the material surfaces and make it easy to join parts together. For more information, please refer to Soldering & Brazing.

Another joint type is threaded which is NPT thread. It is to provide adaptability of copper fittings to equipment or pipes connection that having this thread type. The NPT thread is made according to the requirements of ASME B1.20.1.
