A pressure washer O-ring is a small round gasket that is used to give a water tight seal between your hose, nozzle and wand connections.
And you can see my favorite replacement O ring kit: the Powerfit Oring for Pressure Washers on Amazon.
O-rings naturally wear out over time and eventually have to be replaced. If you've noticed water dripping from a hose or nozzle, chances are you can easily & completely correct this annoying problem by replacing the worn-out o-ring.
I really recommend the Powerfit Oring Replacement Kit on Amazon!
This economical Oring replacement kit has a universal fit for ALL gas pressure washers - and you get replacement orings for your trigger gun, wand, pump and hose.
O-rings are generally made of EPDM rubber, to help ensure a long working life. It doesn't matter if your pressure washer o-rings are made of black rubber or colored rubber, they work the same.
If you're like me, your o-rings will sometimes pop off as you change a nozzle or hose, and because of their small size, I find them very difficult to locate. They roll away very quickly!
But o-rings are very easy to replace and I always have an extra pack of them around.
ANOTHER TIP: When you replace your o-rings, this is an excellent opportunity to check your inlet screen. If it's dirty or clogged, gently run it under the garden hose to remove debris. Be careful to not bend the screen!
You'll get increased and efficient water pressure if you change your o-rings and clean your inlet screens regularly.
