This is an authentic OEM sourced replacement part designed for use with air compressors. Reed valves are commonly used part in two-stroke engines, where they control the fuel-air mixture admitted to the cylinder. As the piston rises in the cylinder a vacuum is created in the crankcase beneath the piston. These valves are made out of metal. This kit includes four (4) valves and eight (8) screws used to attach them.
To complete this repair you will need screwdriver and a set of wrenches.

Repair went well. If you are changing the reeds valves pay attention to the input and output reeds because they are different. You will also need to torque the bolts for the head to finish.
Very easy rebuild from the top end.
