Nice crush washer. Just like nissan sells me.
good price for a package of cooper crush washers for my 2018 nissan frontier. They fit the Engine oil drain plug and the automatic trransmission drain plug. No leaks. Good Product.

Quality crush washers
Fit my 2012 Subaru Outback 3.6L. They work as expected and are of better quality than the crush washers at the local auto stores.

Perfect OEM replacement — great value pack
These OEM-spec drain plug washers are exactly what my Honda needed. I've been using them every oil change and they seal perfectly every time — no leaks, no drips. The crush-seal design works as it should, and the fit on my 14mm drain plug is spot on. The pack of 20 is a great value since you'll want a fresh one every oil change. Much cheaper than buying them one at a time from a dealer and the quality is identical. Will definitely keep ordering these.

Perfect fit. Great value.
Changed my oil yesterday- so far so good. I think they’re a tad on the thinner side than the OEM washers, but fit was perfect, no leaks, and happy that I got 15 washers for the price of 1 OEM washer. My Audi is a 2006. If this thing is still running after 100,000 miles- will order again!

It's an actual "crush" washer. Works perfect
I require a crush washer on my slightly marred drain plug hole (thanks to shop oil changes... BTW, why TF is it so rare to find a shop that doesn't screw up a simple oil change by over tightening everything?) Such a simple job. Anyway if you do your own oil changes this is a real single use crush washer. It gets crushed when tightened, which allows it to conform to small irregularities forming a better seal. But it's also complete toast when used. Drain plug washers are supposed to be single use all the time but you can definitely get multiple safe uses from a robust washer on a robust metal pan. My application is on an Audi Q5. Weak oil drain plug/ hole Sometimes you need a more aggressive fix, sometimes this is perfect. If you don't have a small drip, these are still an excellent choice as they make a better seal at a lower torque value.
