Profile: Lee Brass is a vendor of brass and bronze castings to OEM in a full range of industries. We also manufacture molds. The process begins by melting scrap metal and metals reclaimed from sand. This melted material is poured into brass ingots that are then melted to a minimum of 1,900 F. and poured into molds to form the castings. Routing from the foundries depends on the type of castings being manufactured. Some castings are routed through grinding, machining, and testing operations before being shipped.

Our FF (bronze) fittings are used for brazed connections on I.P.S. brass, copper nickel tubing, and copper pipe or tubing. The FF-W (CuNi) socket weld fittings are designed for connecting I.P.S. copper nickel tubing.
