This is a rugged tyre inflator with a dial reading pressure gauge, more like the one you find at the local garage (or maybe even better!). With a large, clear gauge protected by a rubber housing, it reads in psi, kg/cm², kpa and bar. Cleverly, the gauge swivels to allow left or right handed use. It can also inflate the inside wheel of a twin wheel axle. It has a 1/4" BSP female fitting. For quick release couplings use 100313 or 410251 (swivelling).
