Can I get or change the gauge to a lower pressure range?
Please check-out our Digital tool for easy-to-use pressure readings at any level!
We don’t put lower range analog gauges on our tool, and our custom threads intentionally prevent users from doing this.
Most reasonably-priced consumer air compressors hold anywhere from 100 – 155 psi these days. All it takes is for one-time to forget to unscrew and push the presta valve, and the first shot with the Prestaflator will instantly load the tool with the full pressure of the compressor. If that pressure is higher than the gauge can read, the gauge has been instantly destroyed.
While compressors do have regulators to control output pressure, many consumers don’t understand the need to use them, and even when they do, they might have multiple applications for their compressor and forget to re-set when using a low pressure inflator.
Is it safe to use an air compressor with bicycle tires?
Your concern is exactly what Prestaflator was designed for. The Prestaflator offers a unique variable-rate trigger valve. Short bursts or a light squeeze on the trigger flows less air. Keep one finger or your thumb behind the trigger, and you can easily regulate small additions.
I am not familiar with your Quick Presta heads. How do I use it?
Just push the head onto the valve. Just enough to get past the loosened cap of the valve. You will feel a slight “click” sensation. It’s now on right where you need it. Threadless Presta valves may fall back into the rim when the tire is empty. Push on the tire side under the valve to keep it sticking out.
Why is the head sometimes hard to install or remove from the tire valve?
This problem has come-up more often with a few different brands of newer Presta valves. The problem has been that tube and tire makers increased the diameter of the spin cap of the Presta valve. That caused airflow blockage, and then bikers would push the head onto the valve farther than it is supposed to go. Once it’s on too far, it’s very hard to get off.
We’ve come out with a new design for the Rubber insert that solves this problem. It works great, and it goes on and off all new and old types of Presta valves very easily. All Prestaflator tools and Prestaflator Rebuild Kits shipped after June 10 2012 have this new 2013 model Rubber insert. You can purchase the Prestaflator Rebuild Kit to update any older Prestaflator tool. It also updates similar Silca Pump Heads.
How does it work for Schrader valves?
The hose threads right onto Schrader valves. Our optional Quick-clip Schrader head is high pressure rated and faster for more frequent Schrader use.
Does Prestaflator release air from the tire with the push button?
No. Our Quick heads are one-way only. We’ve designed our tool with a variable rate trigger which allows you to ease-up to the exact pressure you want. And once you take our head off, nothing from inside the tire is lost.
Does the gauge read the pressure in the tire or the incoming air pressure?
Once inflation has begun the gauge shows the pressure of the tire. It holds the tire pressure reading after inflation until the tool or pressure button is released. Technically speaking, it measures the pressure you have allowed to pass-through with the variable-rate trigger into the tool. The pressure inside the tool is equalized with the pressure inside the tire because pressure opens the presta valve. The presta valve closes itself when the pressure on both sides is equal.
Are there different kinds of Presta valves?
Presta Valves (also known as French valves) are standard. The greatest variation is whether or not the body is threaded for a hold-down nut. The Head used on the Prestaflator fits all types of Presta valves. The head maintains contact by friction with a rubber grommet.
