Plastigage Clearance Indicator

(.001-.003 / .025mm-.076mm)

Made from a special extruded plastic thread with accurately controlled crush properties, Plastigage provides a fast and accurate way to check bearing clearances. Plastigage is packaged in a calibrated envelope that not only protects the plastic threads, but also serves as a scale to measure the bearing clearance. One package contains enough Plastigage to check both main and connecting rod clearance for one engine.
