“Consistent, easy and reliable.”

These work perfectly! I wanted them set for 20 PSI and it took me about 5 minutes to adjust them from their factory setting. I've used them four times now and every time they deflate my tires to exactly 20 PSI per my gauge. Customer Review Sep-19

“Great product!”

Excellent product - does exactly what it says. I walked round the vehicle screwing them on one after the other. By the time I returned to the first tyre deflated, it had finished. Very efficient means of deflating tyres. Once more round taking them off whilst checking pressures, and good to go. Easily adjusted to set the preferred psi. Customer Review Apr-18
