How to replace and lubricate O-rings on a high-pressure washer
O-rings are small but essential parts of your Husqvarna® high-pressure washer.
They seal the connection between components and prevent water leakage.
Over time, O-rings can wear out, become damaged or break. When this happens, they must be replaced to keep your washer working properly.
Using the right O-rings—such as original Husqvarna O-rings—ensures a secure fit and reliable performance.
To extend their lifespan, regular lubrication is also recommended.
Why O-rings are important
Seal connections
- O-rings prevent leaks by creating a tight seal.
Maintain performance
- Damaged O-rings can reduce water pressure and efficiency.
Protect your high-pressure washer
- Replacing broken O-rings prevents further wear on other parts.
How to replace O-rings
- Remove the damaged O-ring: Carefully take off the broken or worn O-ring. A small flat head screwdriver or similar tool can help.
- Fit the new O-ring: Slide the correct Husqvarna® O-ring onto the coupling. Make sure it matches the specific connection.
How to lubricate O-rings
Lubricating your O-rings after every use helps reduce wear and prolong their life.
- Detach the parts: Remove the spray lance from the spray handle and then separate the spray handle from the high-pressure hose.
- Apply lubricant: Coat the O-rings with universal white silicone grease. Avoid petroleum-based products, as they can damage the rubber.

- Always use genuine Husqvarna® O-rings.
- Lubricate O-rings after every use for best performance and longer durability.
- By regularly checking, replacing and lubricating O-rings, you’ll prevent water leaks and keep your high-pressure washer working well.
