Faucet Stem Assembly

A faucet stem assembly is a component of a faucet that controls the flow of water. It is typically located inside the faucet handle and connects to the water supply lines. The stem assembly includes various parts such as the stem, seat washer, O-rings, and packing. These parts work together to regulate the water flow and ensure a watertight seal when the faucet is closed.

The stem is the main component of the assembly and is responsible for controlling the flow of water. It is connected to the handle and moves up and down or side to side to open or close the faucet. The seat washer is a rubber or plastic washer that creates a seal against the faucet body when the faucet is closed, preventing water from leaking out.

O-rings are small rubber rings that are placed around the stem to create a watertight seal. They help prevent leaks around the stem and handle. Packing is another type of sealing material that is used to create a tight seal around the stem. It is typically made of graphite or Teflon and helps prevent leaks from the stem assembly.

Overall, the faucet stem assembly is an essential component of a faucet that allows for the control and regulation of water flow. It is important to regularly inspect and maintain the stem assembly to ensure proper functioning and prevent leaks.
