A Guide For Beginners

I have read several how to replace o rings in a pressure washer quick connect nozzle guides. However, there’s rarely one that is beginner-friendly. Thus, I have decided to summarize the steps in an easy-to-understand way.

Step 1: Prepare The Needed Tools.

It will take about 10-30 minutes to finish replacing the o-ring for pressure washer wand. However, if you don't use the right tools, it might take a longer time. Aside from the o-ring, you need tabletop vise grip, wrench, silicone lubricant, screwdriver, and nose flier.

Step 2: Consider Your Safety.

Undertaking any kind of repair work can be dangerous. No matter how confident you are with your skills, you must take the necessary precautions to avoid hurting yourself. This said, make sure that you wear hand gloves. If it is your first time to replace an o ring pressure washer wand, do not rush the process.

Step 3: Remove The Pressure Water Wand.

With the use of a wrench, remove the pressure water wand from the pump. Turn the wrench counter-clockwise to do this. Once done, place it safely on a table-top vise grip. Tighten the vise grip to secure it.

Step 4: Pull Out The O-ring.

Get a screwdriver and stick it into the o-ring. Slowly and carefully, pull out the o-ring until it's in the middle of the pressure washer wand. If possible, completely pull it out. If not, you can use a nose flier to finish the job.

And here’s a very important reminder:

Note that an o-ring that has completely deteriorated will break down inside the pressure washer wand. In which case, you need to make sure that you remove every piece out. This will take a longer time to do. Thus, it’s advisable that you learn how to replace the o-ring in a pressure washer wand before any big damage happens.

Step 5: Insert The New O-ring.

Check the o ring that you have. Is the o ring size for pressure washer wand the appropriate one? If it is, you can proceed to this next step.

It is impossible to insert the whole o-ring directly inside the pressure washer wand. This is because there is little difference between the circumference size of the washer wand opening and the rings. You have to put the o-ring one half at a time. Use a silicone lubricant to make this process easier.

Step 6: Reinstall The Pressure Water Wand.

Once you've inserted the o-ring inside the pressure washer wand, use your finger to make sure that it is seated well in the recess of the nozzle. Otherwise, there will still be a leak. When you’re sure that the o-ring is secure, connect the pressure water wand with the pump.
