Product Description

The STARRETT 64498 is a replacement vial tube and plug designed for precision machinists' levels. This kit provides the vial tube assembly and sealing plug needed to restore a worn or damaged level vial to working condition. The tube measures 6-17/32 inches in length and 3/4 inch in width, and the plug is finished in black.

Installation Notes

Vial replacement on precision levels is typically performed by a machinist or qualified tool technician. Before beginning, ensure the level is removed from service and any retained fluid is handled according to the manufacturer's guidance. Use care when pressing or seating the plug to avoid cracking the tube. Verify vial sensitivity and bubble centering against a known flat reference surface after installation to confirm the level reads correctly.
