So far so good! Used these to replace my ATF drain plug and check plug crush washers after an ATF fluid drain and fill on my Toyota Tundra (2007-2013). These appear to be super close to the factory units. Thickness, bevel and design seem to be near identical to the Toyota parts. Maybe a SHADE larger diameter, but really close. They wiggle on the drain plugs just a tad, while the originals seemed more precisely snug to the plug. But once you crank down the plug, the washer deforms a bit (the crush feature) and the washer snugs-up nicely. I'm not seeing any leaking or weep. I had to reinstall the check plug since Toyota requires filling, running, and re-checking the level from the drain pan. That used-up an extra washer unnecessarily. I should have reused an old crush washer for the "testing" part. But lucky I had 8 to spare in this 10 piece package. I'll have spares for the next round as well. Personally, I like using new crush washers. Once deformed, the washers lose that resistance that helps keep tension between the plug and the pan. And to me, using old previously crushed washers encourages me to over tighten the washer to make it seal again... which is an invitation to strip the pan threads. For the price, I'll order a bag of these every time, no question. And these were a fraction of the price of the Toyota factory washers.

Fit and sealed well. Can’t beat that !

Fit perfectly 2001 Toyota tundra 4.7L. No leaks and not to mention the outstanding price.

Worked as intended. No leaks.

It's a crush washer...plan and simple. They look well machined and the ones I've used have functioned properly.

2014 Tacoma transmission drain and check plug. Perfect fit for both.

Worked great for the drain and fill of the transmission on my 2020 4Runner.

Bought a pack to service my GX470 and my father's Tundra. Fits like factory OE. It's been a few weeks and no leaks.
