Emergency Valve

I don't usually bother with product reviews, but this one was such an enormous help! A corroded valve stem came off with the cap when I tried to add air to the tire, and my tire went completely flat. I can fix a lot of things -- from my roof to my dishwasher, but I've never had much luck with auto repair: I don't have the muscle to use hand tools on a car (I have to jump up and down on the wrench to even loosen a lug nut), and no garage means no extensive collection of specialized power tools which could compensate. The alley where I park is not entirely paved, so even positioning a jack is not easy or safe. Add in cold or rainy weather (meaning numb fingers and slippery mud), and I can *maybe* install new windshield wipers... There was NO way I could have done a traditional valve replacement, even a temporary one to limp the car to a repair shop. I tried walking to the one auto parts store within reach, but they had nothing to offer that would do the trick.These valve stems really seemed too good to be true, but my only other option was getting a tow truck and that's NOT cheap (and getting one to where I live is also not a simple proposition, either). So I ordered them and waited the two days for shipping (this was one occasion where I would have gladly paid extra for overnighting them, but expedited shipping wasn't available?). When they arrived, I studied the design and instructions. It wasn't immediately obvious what the instructions meant by "lip of black seal" which had to be "flush against wheel", but after unscrewing the wing nut from the main body of the stem, I realized the black part on the bottom of the main brass body of the stem, right under the brass washer, is actually a hard rubber, and is meant to get pushed down the widening stem bottom to flare around the inside of the wheel to create a seal. So "lip of black seal" is the fat round rubber lip under the brass washer, and the wingnut forces it down the flared bottom of the brass stem. It is an extremely simple and extremely clever design (clever because it's so simple and foolproof). And yes, it works perfectly and EXACTLY as advertised. All I had to do was push the old broken valve stem into the tire (there was a split and corroded collar around it, holding it in place, which I broke off with some pliers) and push the Colby Emergency valve firmly into the hole that was left. I did bring a toothbrush along and cleaned around the hole as much as possible to make extra sure I would get a good seal, but I don't know if that was strictly necessary. Then I tightened the wingnut on top as much as I could (which also bares more threaded stem at the top to connect a pump or compressor). The tire inflated like a charm (during the inflation process, it becomes possible to turn the wingnut further to tighten the seal, and I took full advantage of this, since I didn't have anything handy to supplement what I could manage with my fingers). There are even valve caps in the package, in case yours became unusable along with the valve, as mine did.The whole procedure took maybe 10-15 minutes, and yes, that was in pretty nasty conditions: barely above freezing with a drizzle and barely enough light to see what I was doing. It wasn't 100% tool free, because I did need pliers to get the old, broken valve stem out of the way, BUT your mileage may vary on that point, based on how you came to need an emergency valve stem replacement in the first place. In any case, pliers are something that most people will have on hand or be able to get hold of relatively easily (neighbors, gas stations, convenience stores are all likely to have some). The installation process itself is really as straightforward as the package promises -- which is rare in my experience. It works really well, too: the seal will hold, you can inflate your tire and drive right away (my tire actually stayed inflated overnight, but I imagine that depends on how well you manage to tighten the wingnut). I love that there are two of them in the pack, too, so I can keep one in the car for emergencies.I just wish these things were more widely known and available, because 2-day Prime shipping is great, but "emergency" implies you might not have the luxury of staying put that long, and most people (including myself) don't realize that their tires might go flat not just from a puncture, but from a broken valve stem, right up until it happens. It's really hard to be prepared for something you aren't aware of. And without the option of a spare tire (my car doesn't have one as standard equipment, and doesn't have room for one without installing some non-standard 3rd party kit to carry it), in who knows what conditions and with a bare minimum of tools cars are equipped with, all the tire repair kits in the world won't help. So the second replacement stem along with the packaging, which I was careful to remove undamaged, went into my purse for now, and I'll try to do a little show-and-tell at nearby auto parts stores and gas stations, on the off chance they can be persuaded to start stocking these, and after (probably) developing a bit of a reputation as a crank, it'll be going into the glove compartment, just in case!

This is an amazing, practical product and absolutely feels like a life saver in an emergency. It gives you a fast way to replace a damaged or leaking valve stem without needing full tire dismount tools or a shop visit on the spot.Installation is straightforward for what it is, and it’s designed to get you back on the road quickly when you’re stuck with a failed valve stem. That peace of mind alone makes it worth having in a glove box or emergency kit.Build quality feels solid, and it’s clearly made for real-world roadside situations rather than perfect shop conditions. It’s one of those tools you hope you don’t need but you’re glad you have when you do.Overall, it’s a smart, reliable emergency fix that can genuinely save you time, hassle, and a tow.

I saw this get used on a trail run where a tree branch got caught inside a vehicle's rim and ripped the valve stem right off. It was less than optimal terrain and weather for changing to the spare, but with a hammer and screwdriver to punch the remnants of the broken valve stem inside the wheel, and a pair of pliers to install this new one, he was airing back up in about five minutes. I was so impressed I asked what they were, and as soon as I got home I ordered some for my own emergency kit.

Worth every money super easy to install just pull or cut out ur ripped one and this one is very easy to push in and can save you time and money depending if u get stuck in the mountains or idk but super worth the money and good to have on hand

Woke up one morning and saw dad's truck had a flat. Went to add air so I can drive it to tire shop but noticed it has blown out at the valve stem.Don't have a jack that'll work for this truck so the valve stem replacements worked great. Removed blown out stem, inserted one of these and screwed I on. Was able to inflate tire and drive it to a tire shop for proper valve stem replacement.While this appears it could be used as a permanent repair, I felt more comfortable having a tire shop so it properly.Saved me time and money not having to buy a jack and remove tire to get it fixed. Just installed, sides up and drove it to shop.

I recommend these for anyone who goes off-roading

Sheared off my valve stem on my jeep while out wheeling miles from a repair shop. Spare was back at camp. These are amazing. Easy to use. And held air. Since then we keep extras in our jeeps. So far we've saved 3 other random people out in the woods with these. Everyone is always surprised how great they work.

These valves are awesome, the reason I'm ordering more is because I just used the pack I had. I had a blowout that shredded my tire, I put on my spare which was low, the valve stem cap was corroded and the valve stem ripped off and deflated the spare tire. Luckily I had a pack of these emergency valves. I popped one of these in and reinflated the spare tire and was back up and running in 5 minutes. I've been driving on it for 3 weeks. Great product! I need to replace the ones I used.I want orange for high visibility to denote it is an emergency valve.

Nice produce for emergency tire repairs.

Very helpful
