Is Fix-a-Flat Safe To Use?

By January 26, 2010

Follow me on:

The stories of bodily injury and death by explosion pop up almost instantly when you mention Fix-a-Flat in the company of a seasoned auto mechanic or tire tech. I say seasoned because it's usually older guys that tell the stories. I'm here to tell you with 100% conviction that Fix-a-Flat will NOT explode! If you're using another product, be sure to check it out, but the Fix-a-Flat brand is non-explosive and can be used without risk of injury to the person who is removing the tire. Messy? Oh yeah. But not deadly. I could go on and on about this, and since I can write whatever I want, I did go on and on about it here! Read up on the history of the explosion myth and why there's nothing to worry about.

I know quite a bit about flammable propellants in aerosol tire sealants, having testified as an expert witness in court trials. You are correct about the timeline for elimination of dangerous propellants. As a tire service professional, i cannot endorse the use of any of these aerosol sealants except in an extreme emergency. These products play hell with future tire repairs, they can ruin very expensive TPMS valve stem sensors, and many users feel that it is a permanent repair– NOT! In addition, metal rim components can be damaged. Whenever used, the tire should be taken to a tire professional ASAP and tell them.. that sealant has been injected. Leaving the material in the tire can also ruin the tire when the liquid component tries to seep back through the tire body and compromises the materials in the tire . This stuff is a crutch, not a true fix. It can also void the warranty of some tire manufacturers

Well, I disagree. Because I had 2 cans of FIXAFLAT spontaneously explode today. I work as a travel nurse and literally drive from one side of the country to the other. I’ve had these 2 cans for apprx 3 years now. They’ve been neatly tucked away in my cargo trailer. They”ve endurred extreme cold(Minnesota in the winter) and extreme heat(Central CA and Southern New Mexico in the summer). They’ve traveled at sea level, and travelled through higher elevations like 9000+ feet. Never any problems. Today I drove from Lubbock, TX to Dallas, TX. When I arrived and opened my cargo trailer, the cans were right where they’ve always been, and everything inside the cargo trailer was covered in this stuff. It stinks, and it won’t wash off. They literally spontaneously exploded. There was no change in atmospheric pressure, and the temperature was pretty consistant in the mid 60′s.

Are we talking about a true explosion that leaves shrapnel bit of can everywhere or simply a valve failure that lets the gunk out all over the place as Brad noted?

The latter is messy but not dangerous, yet many people describe such a failure as an “explosion”.

I wouldn’t recommend it myself, it is dangerous and with all that stories of exploding you might want to consider other alternatives.
