Durable, low cost, high quality
Unbeatable for price. Not chemical resistant, but if you downstream with x jet you don’t need to buy $2.79/each o rings. Been working fine all year on one replacement o ring per hose. Very handy and cost effective

Great O-Rings
These worked great for my Brass quick fittings. Great quality!

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

Just what I needed
Fixed my leaking pressure washer with extra to spare.

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

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.
