The Piston Ring Groove Plug Gauge is a checking tool used to measure the internal diameter of piston ring grooves during inspection work. The gauge helps confirm that the groove size matches the required clearance for correct piston ring movement. Accurate groove measurement supports proper ring seating inside the piston. Correct clearance allows piston rings to expand and contract smoothly during operation. The tool helps identify worn or oversized grooves before assembly begins.Attributes:• Helps prevent piston ring binding conditions.• Improves accuracy during piston inspection procedures.• Assists in controlling oil movement around pistons.Applications: The Piston Ring Groove Plug Gauge is applied directly to piston ring grooves during inspection and servicing tasks. The gauge verifies groove diameter to ensure correct piston ring clearance for proper sealing during operation.
