As the world’s leading linear gauge, the AIRFORCE® MK4 takes performance to a new level, offering even greater ease of use with a 20% larger screen and clearer to read scale. Meanwhile PCL’s leading high performance two-stage valve design ensures accuracy and longer life compared to competitors’ single-stage mechanisms, where filters are used in an attempt to protect the product. This can result in over 50% reduction in product life, with filters slowing down inflation rates, wasting valuable technician time.

Tests show the 'Made in Sheffield' AIRFORCE® MK4 can cover more than ten times as many cycles as its main contender, making it the product of choice for users who prefer a linear tool.
