These O-rings are a perfect fit and a great hack to replace factory GM O-rings for transmission oil cooler line adapters to the radiator. The Buna-N material is resistant to oil & coolant damage. All at a great price too!

This is the exact size for my airhose reel that had leaking orings. No more air leaks!

Like other Harley owners have said, these are perfect replacement for the Harley Davidson 103 oil drain plugs. I used 3 of them yesterday when I changed the motor oil, gear oil, and transmission fluid on my 2014 Road King. HD charges $1.00/each. Finding this package of 100 for less than 3 bucks is awesome. More than I'll ever use, but I'll share them with Harley riding buddies.

These are great for a lot of things but I use them for repairing old action figures like Masters of the Universe toys. Sometimes you need to use two together. You also need #216 screw eyes. I also use 111 Buna-N O-Rings for the MOTU figures.

Perfect size for Harley plugs. Don't waste your money buying from Harley or others. These O rings fit the oil, primary and tranny plugs on a Harley 103 motor. Don't know about other motors. Put 2300 miles on in Sturgis. No leaks. Huge cash saver. And the Viton material is good for higher temps than the stock o rings

This product filled my needs very nicely, and the price was really good. I priced similar items at the local hardware store for 79 cents for two. These are less than 3 cents each. One reason I really like them is that I can lubricate them with generic vasoline instead of having to use high priced silicon grease. I use them in my model airplane pneumatic retract landing gear cylinders. My system now holds pressure for more than a week.
