Hold this thought for a second because it is unnecessary and a waste of money. Replacing an O-ring is one of the easiest works that everyone can nail for the first time. Here in this article, I will give you a thorough guide on how to replace the o ring on a Moen kitchen faucet. Scroll down for more!
What Size O-Ring Do I Need For A Moen Kitchen Faucet?
You will have different replacement part sizes depending on your Moen kitchen model. It is advised that you check the O-ring’s ID number first, take measurements about the size, or bring it to the hardware store to get a new replacement.
The replacement size is the same for all single-handle models, so you shouldn’t worry about buying the wrong one. If you have trouble finding the dimensions, you can read your manual or contact the store for assistance.
Yet, the ID number is normally on the O-ring, which you can use to determine the exact size you need.

When Should An O-Ring Be Replaced?
All machine parts will wear down over time, and the O-ring is not an exception. It is often responsible for leakages, which indicates that you need to replace it. A broken one might also cause high-pressure pulses. If you find the same condition in your kitchen, it’s time to make a change.
How To Replace The O Ring On A Moen Kitchen Faucet
Stick to these 5 steps to get the job done at ease.
Step 1: The first thing you need to do is to shut down the kitchen’s water supply. Some sinks are already equipped with individual shut-off valves underneath them.
Meanwhile, others may require you to come to the basement and activate the main shut-off valve. Drain all the leftover water from the line when the water is off by turning on the faucet.
Step 2: In the handles’ center, use a knife to remove the cap. The locking screw is within your reach. Now, use a Phillips-head screwdriver to take out the screw.
Step 3: Next, you should pull the handle off the valve to take it out. Use an adjustable wrench to reach the remaining nut and remove it as well.
You will find the O-ring inside after moving the cartridge from the faucet valve. Then, use a screwdriver with a flat head to pry it off the cartridge.
Step 4: Apply a generous amount of grease on the new O-ring before installing it. You also need to assemble the faucet and the handle once again. Replace the faucet on the assembly and tighten the remaining nut. Lock the screw cap back after reattaching the handle with the handle screw.
Step 5: Turn the water on at the shut-off valve to check if there is any leakage.
Why Is My Moen Faucet Leaking After Replacing The Cartridge?
Suppose you recently made a replacement of your cartridge to repair a leak, but the situation did not improve. In that case, it is an obvious indicator that you also need to replace other parts, including O-rings and gaskets.
You will need to execute a thorough check to identify precisely where the issue is. The rubber seat can be a possibility since a worn one can cause water leakage through the cracks. An old O-ring might be the next suspect as well, so take your examination carefully.
Now you must have figured out a way of how to replace the O ring on a Moen kitchen faucet. It is not as complicated as you think.
