The Piston Ring Groove Plug Gauge is used to check the internal diameter of piston ring grooves during inspection and service work. The gauge helps confirm that groove size remains within acceptable limits for correct piston ring clearance. Proper groove diameter allows piston rings to move freely while maintaining effective sealing. Accurate measurement helps identify groove wear that can affect compression and oil control. The tool supports technicians in detecting out-of-range conditions before assembly.Attributes:• Checks piston ring groove diameter for accurate clearance evaluation.• Helps identify worn or oversized piston grooves.• Allows clear pass or fail inspection results.Applications: The Piston Ring Groove Plug Gauge is used on piston ring grooves during inspection and servicing activities. The gauge verifies groove diameter to ensure proper piston ring clearance and effective sealing during operation.
