Patent ID: 8567241

Claim:
An adapter assembly for incorporating a tire pressure monitor onto a truck tire pressure inflation valve, wherein said assembly comprises: a) a truck tire pressure inflation valve, with the valve having a stem with a distal end flange, b) a hollow adapter collar having a configuration sized to fit over said stem and be internally retained by said distal end flange, said hollow adapter collar having external monitor mounting means, with the adapter collar providing an interface with said tire pressure monitor, said adapter collar further comprising a cup-like configuration with an inner diameter sufficient to clear the outer edge of said valve stem distal end flange, wherein said adapter collar having a clearance hole within an end forming an inward-facing lip, wherein the lip inner diameter is dimensioned to permit the inflation valve stem to slide unrestricted within, and the lip interfacing with the distal end flange on a side facing a valve core proximal end, thereby permitting said inflation valve to incorporate a tire pressure monitoring system (TPMS), and c) a modified aftermarket grommet fastened onto said adapter for interfacing between the adapter and a truck wheel, thus preventing possible minor leaks.
