Pack of 10; M10 aluminum drain plug sealing washers. Soft tempered aluminum compresses to seal in fluids. Most OEM's recommend replacing sealing washers at each oil or coolant change. Dimensions ID: 10mm; OD: 14.5mm. Meets or exceeds OEM specifications.
Ordered once, I received 5 aluminum and 5 copper washers, requested an exchange and received back 5 aluminum and 5 copper washers. The item description is incorrect and should be removed from sale immediately.
I bought this product and it does not match what was advertised. 5 out of 10 crush washers are copper, not aluminum as advertised. The outer diameter of copper washers is also smaller than that of aluminum washers. Wouldn't buy again.
Good price but very soft material. Yes they are sealed but I could barely get the banjo bolt to the required torque. After that, the washer was crushed into threads, and I had to cut them with dykes. I'm sure they will do for some applications but I reinstalled the original ones on the bike I was working on.
