R4072C Dual-Foot Pencil Pressure Gauge

The R4072C shares the 20 to 120 psi range of the R8100C but adds a dual-foot fitting, letting the same gauge connect to valve stems from two different angles without repositioning the whole tool.

That dual-angle head is particularly useful on dual-wheel trucks and buses, where inner and outer valve stems often sit at slightly different orientations that a single fixed-angle gauge foot can struggle to seat against cleanly.

For technicians working through a full set of commercial dual wheels, the added flexibility of the two-way foot can speed up a pressure check round by reducing the fumbling that comes with awkward valve angles.
