O-rings are used to seal joints in water fixtures, preventing water from leaking out.
What are the different types of O-Rings?
There's one type of O-ring, which is usually made of black rubber when used in home plumbing. The size of an O-ring can vary between faucets and other fixtures.
How do you size an O-ring?
O-rings sizes are usually given as the thickness of the ring and the inner diameter. The best way to be sure you get the right size O-ring is to shut off the water supply line to a leaky faucet, then take the fixture apart and match the replacement.
