Precision Bore Glass Tubing

PEG specializes the manufacture of Precision Bore Glass and Quartz Tubing. With more than 140 spindles available to run simultaneously, PEG has the ability to accommodate prototype to production quantities in a vast range of shapes and sizes. Inner diameter sizes range from .011” to 10” with the ability to hold tolerances as tight as +/- .02%.

Typical Components: Syringe Glass – Borosilicate and Quartz Precision Bore Tubing – Flowmeters

Our ultra accurate precision bore (PB) shrinking results in tubing that meets or exceeds inner diameter (ID) tube requirements. We shrink inner diameters from 0.011” to 10” with tolerances to +/- .02%. With our 1 to 20 burner machines and more than 140 spindles, PEG has the ability to accommodate small to large runs.


Here at Precision Electronic Glass, our commitment to quality drove us to developing a smoother, more accurate bore. Now, after painstaking R&D, we are pleased to announce a significant product advancement. “Best Bore Tubing” is a superior precision bore glass tubing product with a smoother and more precise inside diameter (ID) for improved feel, higher accuracy and longer life. Our Best Bore Tubing is optimal for applications ranging from syringe glass to fluid flow and volume measurement depend on tubing made to tight tolerances for consistent, dependable performance. Diameter, roundness and internal surface finish determine how smoothly a syringe piston fits, slides and feels in the bore.
