Precision Bore Glass Tubing for Your Industrial Needs

Precision bore glass tubing and precision bore quartz tubing that meets the highest standards.

Among the hallmark products of Precision Electronic Glass (PEG) are precision bore glass and quartz tubing. With our ultra-accurate precision bore (PB) shrinking process, our glass and quartz tubing meets your most stringent inner diameter (ID) requirements. As a result, we produce inner diameters ranging from 0.011” to 10” and meet tolerances of +/- .02% on more than 140 spindles available. In addition, PEG accommodates prototype to production quantities in a vast range of shapes and sizes. Therefore, PEG is well positioned to manufacture for your unique needs.

Quality is at the forefront of the PEG team. For example, we have inspectors in each department ensuring that your components meet your specifications every step of the way. Finally, once your components are completed, our quality team completes a final inspection before the team packs and ships to you.

Consequently, PEG accommodates prototype to production quantities in a vast range of shapes and sizes.

Similarly, our typical components include syringe glass, flow meters, precision bore tubing, capillary tubing, laser components, and more.

PEG Components Help Make Your Great Products Even Better

Our components are found in an array of applications. For instance, our unique pneumatic actuator products provide unparalleled force accuracy by eliminating friction from the working elements. These products satisfy actuation requirements. They range from undemanding levels of air cylinder force output for the most basic uses to almost imperceptible degrees of accuracy for the most precise applications.

Similarly, you will find our PB glass used in precision fluidic components for analytical and clinical chemistry OEM instrumentation. For example, our parts are used in precision glass syringes, rotary/shear valves, and positive displacement pumps.

Our OEM customers use PEG PB components in a wide variety of applications ranging from cutting-edge laboratory and medical uses to advanced instrumentation in labs, transportation, research and development, and much more.
