  • O Rings
Price was right and the quality appears to be sufficient.

  • Stopped pressure washer leaks
Replaced all the O-rings in an old pressure washer. With a tune up it runs like new and doesn't get me soaked from all the previous leaking points.

  • Check your sizes
No fault of the vendor. Didn’t fit my standard pressure washer hose. Smaller ones fit. Larger ones too big. I realize this sounds a little weird, but each pressure washer connection has 2 O rings., one small, one big. Took a chance this kit would have the correct sizes. It did, only in part

  • Essential spare parts
Fast shipping. Convenient kit to have on hand for pressure washer connectors

  • Every size I needed
Probably not for every sprayer, but they fit mine. Affordable and I have a couple of spares.

  • Both sizes in one package..was perfect combo for my power washer
These were perfect and I love the fact that they are two sizes because my power washer uses two different sizes and this was just perfect foe me. Very durable as well.
