These rings work well. I was able to replace a few power washer fitting heads instead of throwing them in the trash.

Colors are actually Orange and Mid Gray. Quality is fine.

  • Worst O-rings I’ve ever purchased. Spend your money elsewhere.
Avoid these. Seriously! These O-rings are extremely poor quality. After minimal use, they swell up, causing quick connect fittings to become nearly impossible to disconnect by hand. On top of that, they leak constantly and in some cases fail completely spraying water everywhere. During a simple two car driveway wash, I had to replace the 1/4” tip O-ring twice, once because it completely fell apart and the second due to leaking. I also had to replace the O-ring on my wand twice because it swelled and locked up the connection. Now it makes sense why they include so many in the pack. You’ll be stopping to change O-rings and burning through the pack. Worst O-rings I’ve ever purchased. Spend your money elsewhere. ... show more
