How to Replace O Rings in a Pressure Washer Quick Connect Nozzle

You've tried every way imaginable to replace o-rings in a pressure washer quick connect nozzle, but you still aren't successful. At least not successful without first injuring your hand and spending lots of time trying to get out the old o-rings and put in the new ones. Don't fret; unless you've been shown the technique explained here, like many others, you'll keep wasting tons of time and using lots of small bandages for your injuries trying to replace o-rings in a pressure washer quick connect nozzle.

Difficulty: Moderately Challenging

Instructions

Things You'll Need:

• Flat-tip screwdriver (1.4 mm x 4 inches)
• Straight long-nose needle-nose pliers (long-neck, 5 inches)
• Table-top vise grip (optional)

Removing the Old O-Ring

1. Insert the quick connect nozzle into the table-top vise grip, with the O-ring end at the best position for you to work. If you don't have a table-top vise grip, firmly hold the quick connect in one hand, with the O-ring end toward you.

2. Stick the screwdriver into the O-ring with enough force so as to actually stick it into the old O-ring. With a precise and careful motion, gently pull the screwdriver with the O-ring now stuck to it out toward the middle of the inside of the quick connect. (Your goal at this point is to partially get the old O-ring out of its groove.)

3. Pull the screwdriver up out of the middle of the quick connect, trying to get out the old O-ring as you bring the screwdriver back out of the middle of the quick connect. It's OK if the O-ring no longer remains stuck to the screwdriver.

4. Insert the needle nose pliers into the middle of the quick connect and pull out the old O-ring. If you can only get part of the old O-ring out because it has deteriorated, repeat the screwdriver to pliers process until it's all out.

Inserting New O-Ring

5. Replace O-rings in a pressure washer quick connect by inserting the new O-ring into the middle of the quick connect one half at a time. With one half of the O-ring closer to the groove where it functions than the other half of the O-ring, gently use the screwdriver to start to place the O-ring into its groove.

6. Use the small flat-tip screwdriver to gently work one piece of the O-ring at a time into its groove. Do not rush to insert it; there is no shortcut to inserting the new O-ring.

7. Use your finger to feel the O-ring to make sure it is flush in its groove. If the new O-ring is not fully seated, use the screwdriver to press it into its groove.

Tips & Warnings

• If the quick connect is not in a vise when replacing the O-rings, be careful not to stick yourself with the screwdriver when trying to remove the old O-ring.
• Ensure the new O-ring is seated into its groove. Not doing so can result in personal injury once its under pressure.
