If you get tires at COSTCO they use the same king of caps with inner seals. If you got ripped off at a dealer and got a Nitrogen package for hundreds of dollars for $5 of nitrogen + labor they put on caps with inner seals. The air you breathe is 80% nitrogen, so you are really paying for the other 20% to be nitrogen in your tires. Put these caps on as replacements for them or just replace your old or missing caps in any color they have. I got green because all my tires came from COSTCO. I don't know how much difference having seals makes, but it will keep the air better in at the valve, so this may be the real reason Nitrogen filled tires need less refilling not the old story that the molecules are bigger so it is harder to get through the rubber. Anyway, I like these and I keep them in the glove box to replace those stolen or not put back during tire rotation.

I ordered this set of value caps to replace some I had lost previously. The shipment arrived in 2 days and the caps fit perfectly on the valve stems of the tires on my Toyota Highlander. The best part was receiving an email from the customer service department, thanking me profusely for the order with such humor and enthusiasm that I still have a smile on my face! It was a pleasure being able to write a such a positive review, not just for such a great product, but for the talented people who sent the email as well! Keep up the good work.

I appreciate having a bag of 25 valve stem caps to keep in my glove box. I'm forever needing one cap, and can't seem to find them at a convenience store when I discover that I've lost one. These caps are great--there are 25 and the price was cheap! I'm getting another bag to keep in the horse trailer. But the coolest thing about this purchase was getting a humorous email from the seller, graciously thanking me for the purchase. If every company took the time to send buyers a heartfelt 'thank you' to each buyer, there would be far more goodwill being spread around!

What can I say, they are black, plastic, have a gasket in them to help prevent leaks, and there are 25 of them (which I assume is more than I'll ever need, but with something so cheap I guess it makes no sense to sell them in 4's). They did seem to screw on nicely, so I'll give them that. Anyhow, I'm happy with them and since the sellers send you a hilarious email asking you to review them I figure I should because the product is good and the email made me laugh.

These universal stem covers are not your average, run-of-the mill valve stem covers! They actually thread easily onto the valve stem and don't strip if you try to tighten them, as some inferior valve stem covers do. The best feature, however, is the rubber o-ring which provides a nice tight moisture seal for your valve stems. In a package of 25, they could supply all your valve stem cover needs for months, if not years!

Picture this: I arrive home from work after a long, bruising commute and discover to my delight an Amazon package nestled in my mailbox. "Could this be it, is it really true? My tire valve caps have arrived!" With trembling hands I cradle the package as I enter my front door. I gently place the package on the dining room table as I quiver with anticipation (and the need to pee - long commute, remember). Back to business, I tear open the package and bask in the warmth and glow of the big "THANK YOU" that washes across my grinning face. It doesn't get any better than this! If you plan on ordering from this seller be prepared to have your day brightened with a "Thank You" e-mail that will make your smile soon after you hit the "Submit Order" button. If we all took a little more time to add a little humor to someone's day, this world would be a better place indeed. With that said, the caps fit, they do their job, and the price is more than reasonable.

For such a little, inexpensive item, these are so important to the life of your tires. Some valve caps don't cover the entire threaded portion of the valve stem, letting water and gunk seep in and ruining the tire valves and causing problems. These cover the entire threaded portion of the valve stem and has a rubber gasket inside to seal things up. Would buy again.

First the (redacted) Mueller Report was released. Then, an event occurred that made me forget all about the Mueller Report -- my 25 pack of (unredacted) Valve-Loc Black Tire Valve caps arrived. I sat on my front steps all morning waiting for the postman to arrive. He didn't need to ring twice; I was right there waiting for him. All I can say is WOW! These are absolutely the finest black tire valve caps I have ever seen. I immediately installed one on my left rear tire and, believe me, I am so proud of that tire and its beautiful cap. Thank you for making my day complete. Now perhaps you can suggest some uses for the remaining 24?

Not sure if someone is stealing my tire caps or they fall off, but one is missing every couple of months. The ones my local repair shop / gas station gives me are free but tiny compared to this. These are larger and screw on all the way to the bottom of the valve. Maybe now they will not fall off?? Happy customer.

Pretty good quality affordable caps with O-rings. Would definitely buy again once I run low. Put them on my 2018 12 foot utility trailer, 2017 ford explorer, and 2018 hyundai accent. Perfect fit on everything.
