Danco 88569 Rubber Flat Washer, 1/2-Inch, 10-Pack, Carded , Black

I bought these washers to replace washers that had disintegrated in the 29-year-old shut-off valves in my home. With a little silicone lubricant to get them to slide on the appropriate stem inside the valve, they worked fine and provided a solid shutoff of the water supply to a sink faucet when needed.

Got tired of needing plumbing washers and not having the one I needed and having to go to store and pay a couple bucks for one washer.

The Danco 88569 Rubber Flat Washer, 1/2-Inch, 10-Pack, Carded , Black (New) arrived by the expected delivery date and were new and unopened in the original factory packaging. The washers are as described in the offering. The only negative thing about them is that they have raised lettering on one side but that shouldn’t affect their ability to seal.

Good quality.

I used these in a non-conventional way, so my review shouldn't hold much weight for the intended purpose. I used a couple of these as washers for a fork crown bike light mount that wasn't clearing the headset. Worked great for this purpose.

Works just fine as a seal on a drain with tube for the washing machine water

I purchased a house recently and noticed that most of the shutoff valves needed to be replaced, which could be quite pricy for 6 sinks and 3 toilets. After working through some possible solutions, I realized that the replacement stem kits don't work out very well, because the stem dimensions vary slightly with each vendor. Replacing the shutoff gasket and re-using the existing stem is far more reliable, while also being much cheaper than replacing the entire valve. One issue I ran into while doing the work is corrosion in the pipe and existing valve, which can tend to make it difficult to get a good fit for an OEM gasket matching to original size. Using a size smaller works better for doing the replacement. These gaskets were just about the perfect size. They are a hair smaller than the original, while still sealing off a half inch inlet. One request I'd like to make is that they make these in silicone. I find silicone remains pliable for ~20 years, so effectively would outlast the house. SBR or NBR rubber is organic and subject to oxidize, usually within about 5-10 years. Give me the exact same product made out of silicone, and it would be that much more perfect.

perfect fit for my shower stem. came on time.

Muito Bom

I changed it in my hot faucet and no water leaking more

Not worth the cost

ok product

Os produtos vieram de boa, dentro do prazo. Porém são bem menores do que a imagem sugere. Acabou que ficou sem utilidade e deixei guardado e tive que cortar uma sandália para fazer a arruela que eu queria
