Valve Lapping and Grinding Equipment

The LarsLap valve lapping system comprises a number of basic models that cover virtually every type of valve, from 1/4" to 52" (8mm - 1300 mm) in diameter. The patented LarsLap technology uses a mechanically driven system whereby the rotating drive head incorporates individually driven grinding wheels to perform the actual work of the seat grinding. This unique tool provides the desired crosshatch pattern on the valve seat considerably quicker than conventional methods of valve grinding. Our versatile accessories for all types of lapping work are the ideal complement to the basic portable valve grinders.
