These work but they are very flimsy and very small compared to what is actually needed for most vehicles. We shall see how the hold up.

Jacob Martinez
Good range of sizes for use in multiple applications

These automotive cap plugs sold by Solary come in a bag that includes 8 sizes that can be useful for capping or plugging ports or pipes when working on your vehicle or other applicable projects. As the included sizes are all different, you'll be limited if you have two or more holes or pipes of the same size. They are fairly soft and so can be deformed slightly if they are close to being the right size. I have a stash of old bottle caps and lids that I've save for situations like this but these are much better suited due to their flexibility. It's by no means a complete kit and for the current price of $12.99. they're a bit pricey for what you get. If you work on cars and have purchased replacement pumps or other ported components, then you may have saved the plugs that come with these items. This kit will make a good addition to your stash but finding the right size may still be pot luck. 4 stars.

Good light-duty plug

I purchased this to be used to block coolant and oil lines while I replaced a turbo on my 2011 F150. These plugs worked just fine to stop gravity flow. No complaints. Probably not a good method for plugging a pressurized line
