uxcell 40pcs Round Rubber End Caps 1/8" 1/4" 3/8" 1/2" Black Vinyl Cover Screw Thread Protectors Assortment Kit(3mm 6mm 9mm 12mm)

This uxcell 40pcs Round Rubber End Caps 1/8" 1/4" 3/8" 1/2" Black Vinyl is a nice assortment of very nice little caps. The quality of the caps appears to be very good; they are well made, and just the right material for a vacuum cap, nice and supple, but not flimsy, and the assortment provides a good range of sizes. I work on my cars, and occasionally need vacuum line caps. I have an assortment of vacuum caps, but I needed a 1/2 inch cap. I had put a short length of clear vinyl tubing on the radiator drain of my car so rather than spill coolant over the car frame, the coolant comes out the tubing straight into my drain pan. I used the 1/2 inch cap from this assortment to plug the end of the drain hose to keep the hose clean. It fit the 1/2 inch OD drain hose perfectly, snug enough to remain in place, yet should remove easily. As others have noted, these caps come in handy for many other uses as well. I am very happy with my purchase.

These smallest wire covers recovered the naked prongs for better grip on 2 KennelCab dog kennels for small dogs. The trick is to warm the plastic with a hair dryer as needed to ease them over the ends and into place. Voila!

Have helped on our wire racks in the garage. Only gave it 4 start because I wish there were more medium size and not large or tiny. So far we haven’t found use for either. But the medium size ones fit well for our use and we like the bright orange.

Keeps pipes clean in HVAC. Just slip one on an open pipe to prevent contamination…..several sizes comes in the kit.

used this for a new tip in marine antenna and it was perfect

Be careful, not compatible with US sizes. These are sized for metric use and do not fit US inch sized components.

Good variety of sizes, using on the sharp ends of tools and to cover the ends on grease guns

I purchased these caps to cover the feet of an antique vanity stool. They fit perfectly and the package contains additional sizes that will work well for other applications. The clear finish is great, and they are easy to apply.
