Perfect fit

It’s too thin if you use it for engine oil plug.

Bought these to redo a fuel system on an old 1978 international high lift. Have found many other uses where they are handy. They seal up better than the factory brass washers. If they were purchased separately, this kit would cost hundreds. Well worth the price.

Good quality a must in any shop

Great deal and fine quality, would recommend.

Very fast delivery and product is exactly as described!
