Quality
Prestaflator is engineered specifically for the needs of bicycles and bicyclists. Only top quality materials are used for it's components. We start with a cast Aluminum body and give it a bead blasted finish. Next we use Brass, Aluminum, Chrome and Stainless Steel components for all connectors and moving parts. The industrial grade hose is rated for 300 PSI of continuous use.
Prestaflator's unique variable-rate trigger plunger is long and narrow. This allows the user to more easily regulate very small amounts of air to reach the exact pressure desired in even the smallest racing tires.
The pressure gauge has a rubber shock housing and offers accuracy with +/- 2%. The dial has a bicycle-specific pressure range of 12 Bar/174 PSI. It's high enough to inflate any daily-use tire, but not excessive so the gauge is easy to read.
Serviceability
Prestaflator is designed to offer years of reliable service. The body has a ¼" NPT male threaded adapter so you can install any type of connector. It comes with the most commonly-used ¼" I/M Quick Coupler already installed and ready to use right out of the box.
The hose, trigger and pressure release mechanisms are all threaded and installed using #7 O-Rings. They can all be removed and serviced with a 14 mm wrench.
The Presta / Schrader head is made of all brass. This is no place for plastic. Drop your hose on the concrete with a plastic head and it could break. The Presta head connects to your tire valve with an industry standard "24.1 pump head gasket". Replacements are available through any cycling supply source.
Automotive Inflators
Automotive inflators are not the same and may not be safe at bicycle pressures. Don't let a high pressure gauge fool you...inside their package are safety warnings. Even one with a 230 PSI gauge may only be rated for 70 PSI maximum use. Their lower-grade air hoses may burst or the small 'quick-clip' Schrader connectors could blast off the wheel. Basic metal parts are usually glued-on and cannot be serviced. Leaks develop and then you get no reading from the pressure gauge. Failure and disposal of automotive inflators is common.
Prestaflator is different ... a high quality, serviceable tool ... designed, built and warranted for use on Bicycles.
Very useful, unique cycling product.
