O-Ring
Definition and meaning of O-Ring in real estate.
An o-ring is a small, doughnut-shaped rubber or silicone washer used to create a watertight seal in plumbing fixtures such as faucets, valves, and pipes. By compressing between two parts, this ring prevents water from leaking out of the fixture during use.
In more detail
Over time, these seals can dry out, crack, or become worn down due to friction and minerals in the water, which leads to slow drips and leaks. Replacing a worn ring is one of the most common and inexpensive home maintenance tasks a homeowner can perform.
During a home inspection, inspectors will often check faucets for leaks that indicate a failing ring or valve seat. Understanding how these small components function helps buyers and owners maintain their home plumbing systems and prevent water damage.

Frequently asked questions
How do I know if a leaking faucet is caused by a bad o-ring?
If water is leaking from the handle of the faucet or the base of the spout when the water is turned on, the issue is typically a worn o-ring.

No, they come in many different diameters and thicknesses, so it is best to take the old ring to a hardware store to find an exact match.
