Solary Automotive Cap Plugs Kit - 8 Piece Set

I love this. If you have the smoke kit to test for vacuum leaks this is a must have. Makes the job so much easier instead of having to look for random stuff to block off different lines or hoses

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.

Plugged all the holes in my fire wall for blasting and painting. What a great set!

Works well nice adapters this is essential for diagnosing vacuum leaks

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.
