    • Good choice
Great to have on hand in case one breaks.

    • 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

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

    • Great to fix leaky power washer hose
Great as an alternative to buying a new power washer hose

    • Sizes are not as marked
This item is advertised as 1/4" and 3/8" connectors. The item page does not specify whether that's inner or outer dimensions (I'd presume inner). Either way, the actual dimensions (inner) are 3/8" and 1/2", not 1/4" and 3/8". Other than that, the item seemed fine - they are O-rings.
