What is a Staun Automatic Tire Deflator?

The Staun Automatic Tire Deflator is an inexpensive accessory used for airing down tires. The brass tire deflator screws onto any standard valve stem to automatically deflate the tire to a pressure of your choice. Adjusting the pressure setting for the deflator is as simple as turning the knurled pressure adjustment knob followed by tightening the lock nut.

Includes four adjustable deflators in a leather carry pouch.
Helpful hints for using your Staun Automatic Tire Deflators
1) Each 360 degree rotation of the pressure adjustment knob varies the pressure 6 PSI.
2) When the Tire Deflator has not been used for a long period of time, the deflator pop-off valve may stick to its seat. To ensure accurate operation of the deflator, pull the pop-off stem to unseat the valve prior to attaching the deflator to a valve stem.
3) Rather than setting all four deflators to a single pressure, set two at your rock crawling pressure and the other two at your sandy trail pressure. Mark each pair for their intended use. When airing down, attach the deflators to two tires. When the deflators stop bleeding air, move them to the second set of tires to be aired down.
4) When you have finished airing down, remove the Staun Automatic Tire Deflator from the valve stem... this will reduce the chance of snagging the valve stem and deflator on an obstacle.

Can't wait to start your trail ride? Simply attach the Staun Tire Deflators to your valves, hop in, and begin your trail ride. When the Staun Tire Deflators have done their job -- you're finished airing down; hop out and remove the deflators.
