The Dunn & Watson 4 Way Tyre Inflation & Deflation System is designed to save time when adjusting tyre pressures on your 4WD, ute or touring vehicle. Instead of checking and adjusting each tyre one by one, this system allows you to connect up to four tyres at once, helping you inflate, deflate and equalise pressures across all connected tyres.
It is ideal for beach driving, off-road tracks, corrugations, overlanding and remote touring where tyre pressure changes are part of every trip. The built-in backlit digital gauge reads up to 200 PSI with ±0.1 PSI accuracy, giving you a clear pressure reading while the quick-stop slider makes airflow control simple and convenient.
The system features premium TPU braided air hoses with a working pressure rating up to 300 PSI, push-on lock-on tyre chucks, auto shut-off couplers and rubber hose-end protectors to help keep the chucks cleaner during use. Supplied with a range of adaptor fittings for common compressor setups, this is a practical air management kit for serious 4WD owners who want faster, cleaner and more consistent tyre pressure control.
