Precision Bore Tubing involves the heating and shrinking of standard tubing over a precision mandrel when precise ID specifications and tolerances are required. The quality of precision bore is in the quality of the mandrill and the experience of the glass craftsman.  Using only the finest stainless steel and titanium mandrill, we can exact inner diameter (ID) tolerances of ± .001" with flawless finish lending itself to any industrial or laboratory process without interruption of flow. Using automated grinding and polishing equipment for concentric grinding and polishing of the outer diameter (OD), we can guarantee repeatability on each and every piece.

Chose from our vast array of glass types to fit your application. Sizes range for .015" to 10" ID.  Using the top brands of material such as, Pyrex 7740®, Duran 8330®, Kimax KG33®, Corning 7056®, Schott 8250®, Kimble EN-1®, and Quartz, we can meet any requirements of your specifications.
