Staun Tyre Deflators are by far the quickest and easiest way to reduce tyre pressure - say goodbye to the hassle of fiddling around with keys, matchsticks, or poor quality devices.

The deflators are supplied at a preset pressure, however you can adjust this pressure to your desired level. It is not necessary to reset them again unless you wish to change the psi that you want to reduce your tyre pressure to.

This unique set comes with 4 Standard deflators and 2 Heavy Duty deflators. Designed to suit those who tow camper trailers and vans off road and on the beach. While your 4WD tyres are deflated to your preferred pressure, the trailer would normally deflate to different pressures based on the weight of the trailer/van.

This set allows you to deflate your 4WD and trailer at the same time without having to adjust your 4WD deflators to deflate your trailer/van. Your 4 Standard deflators are preset at 18psi and the 2 Heavy Duty deflators are preset at 22psi.

They are fully adjustable Each valve has an adjustment range specific to the level of deflation you require They are easy to use, not requiring any tools They are highly accurate, deflating to within 0.05psi of the preset pressure they have been adjusted to They are the smallest tyre deflators available measuring only 30mm x 15mm (1.18" x 0.6") They are one of the lightest deflators weighing only 32 grams (1.13 ounces) They are made of 100% brass They are the fastest deflators on the market (tests found a normal 10rx15 tyre takes approx. 1 minute and 30 seconds to deflate from 32psi to 18psi) Every valve is completely pre-tested to ensure high performance They are covered with a 5 year guarantee They can be used for all types of four wheel driving ranging from coastal sand driving, desert sand driving, rock climbing to mud driving.
