Brass Faucet Cartridge Stem

The item appears to be a used brass faucet cartridge stem, held in a person's hand. It is characterized by its elongated, cylindrical shape, tapering slightly towards one end. The primary material is brass, evident from its tarnished, dull brown to greenish-brown patina, indicative of oxidation over time. The stem has a smooth shaft for the majority of its length, with evidence of some minor surface abrasions and marks consistent with removal or previous installation. At one end, there is a distinct, circular opening with an internal 'C'-shaped or crescent-shaped void, suggesting a mechanism for water flow control or a key. The opposite end, partially visible, shows threaded sections and what appears to be a rubber or synthetic O-ring or washer, crucial for sealing. This end also displays a lighter, perhaps less tarnished, brass tone, possibly from being encased or protected. The overall length is proportionate to what a person can comfortably hold in their fingers, likely around 3-5 inches. The craftsmanship suggests a manufactured plumbing component, designed for a specific function within a faucet assembly. Its worn appearance indicates it is either a removed part needing replacement or a component from an older, disassembled fixture. The presence of threading and a sealing mechanism points to its role in regulating water flow.
