A good ol' Aussie bush salute to all caravanners, motorhomers and truckers - the Heavy Duty Staun Tyre Deflators 15-55 psi is for the big, beefy vehicles going off-road.

This pack of 100% brass beauties is suitable for vehicles over 4-tonne. They feature an extra exhaust hole, come preset at a pressure of 35 psi, and are accurate to within 0.25 psi. The cap can be adjusted at 4 psi per half-turn or 8 psi per full turn, as well as automatically started while 20 psi above its preset pressure. When manually lifting the piston, the deflator can start at 2 psi above the preset.

Finger grip grooves make for easy handling, and the lock ring can be tightened by hand - so no tools are needed. With 4 in the pack, achieve multiple tyres deflating at the same time simply by screwing onto the valve stem of each.
