The patent pending Colby Valves are the first tire valves made to install from the outside of the wheel, without any tire removal. Have a broken valve stem? Replace it in less than 5 minutes with our valves.
Our XL Valve is 5/8" sized for larger wheels and tires. These fit tractors, backhoes, skid steers, hay balers, heavy duty trucks, etc. They can be installed anywhere, from the outside of the wheel, without tire removal, in 5 minutes or less. You will need to tighten the XL Valve down with a 9/16" socket or a wrench. They are custom machined from 360 brass bar stock to our specifications. This results in a valve that is 20X stronger than standard valves. They aren't indestructible, but they will take one heck of a beating.
- Installs from the outside of the wheel!
- Fits large 5/8" (.625) wheel openings
- Installs in about 1 minute
- 20X stronger than standard valves
- 9/16" socket or wrench required for installation
- Available in single packs
- Quality 360 brass components
- Made in the USA

Bought this a spare for my tractor liquid filled tire. Already have replaced one tire valve with this product and am totally impressed with the quality and ease of installation. Saved me hundreds of dollars in having a repair done to fix a leaky valve stem.

Absolutely a great piece of kit to have in the shop if your an active shop person or any other purposes. A great idea saving you down time by being able to change out that broken valve stem out in the field or just at your shop. Tires are a pain to deal with at the best of times and tire shops are getting more and more expensive. I broke a good handful of valve stems from trailers to machinery and was able to fix them right where i was. The only down fall is that they are only a certain size -meaning when you buy a pack of them, your equipent or vehicles may have different size valve stem holes...if the hole is to big, then your hooped, if it's to small, I have taken the grinder to shave the end of the replacement down some to fit and it worked out great! Highly recommend this product...it's invaluable!!

I keep one in the truck and it bailed me out in the hayfield on a Sunday afternoon on my big tractor. Was back up and running in the time it took to air it up

These things are an absolute must for roadside emergencies. It seems that a large percentage of my flat tires are caused by cheap junk valve stems. Thes things make replacing a valve stem a very simple matter. Cut the cheap rubber valve stem off and install one of these then add air. It takes a lot longer to air the tire up than it does to replace the valve stem.

What a perfect idea from the seller for my farm tractor. No need to remove the tire from the rim. It's too cold outside to do it today but will install it as soon as weather breaks. This product saves us from an expensive service call to have the valve stem replaced.

Tend not to do reviews. This was a savour. I have an old skid steer that has heavily worn tires and rims with lip damage. I found one tire was flat, when I went to fill it, I found the rubber stem was cracked and leaking. Thus leaving me no other choice but to buy a full set of mounted tires. I tired a standard rubber stem, which was too small and did not seal. Then I found this, it was a very quick install and it worked. Now able to clear my driveway again.

It is very well made. The valve stem hole must be the exact size or it doesn't collapse enough. If the rim is thin; this prevents the device from tightening enough.

Accidently knocked the valve stem out of 944 loader wheel. This worked like a charm. Could be a but longer as loader rims are thick, but it worked and is still holding strong. Happy to have not split whe rim.

I ordered the smaller valves without realizing my tire had a larger hole. The smaller valve could slide right in, past the lovely machined brass device. I modified it and got it to seal, but this involved lots of work and rough handling. No worries, their rubber and brass held up to whatever I threw at it. I was able to seal with the wrong size valve, but I'm not confident it will hold long so I ordered this one to replace it. These valves are REAL easy to install and the WORk. Also, I'm an Engineer so I love just looking at them. They are solid brass, look hand made, and have the overall feel of quality. If Rolls Royce made valve stems, these would be the one.
