The Spiratex Co. will design custom tubing to your exact specifications. From simple round tubing with an inside diameter and outside diameter, to more complex pieces like square tubing, rectangular tubing or special hollow shapes, we can create custom tubing in nearly any configuration. Request a quote for your next project. UHMW/PE Tubing The Spiratex Co. specializes in custom extruding UHMW/PE tubing to tight tolerances on the Outside Diameter (OD), Inside Diameter (ID), wall thickness, ovality (roundness), and bow (the extent of bend in the tube over a distance). We offer a wide range of tube sizes and use our proprietary process to create a superior glassy, glossy surface finish. Our exceptional engineering and process control allow us to make the RAM extrusion lines disappear to a much greater extent than other manufacturers. If we don't have the exact standard size tubing you need, we can create custom sizes to meet your requirements. Tubing Tolerances The Spiratex Co.'s standard tolerances for the ID, OD, Ovality, and Bow of our tubes are shown below. Tighter tolerances are negotiable for certain applications through discussions with our expert engineers. Looser tolerances than the standards can reduce costs in some applications where such tolerances aren't critical to the functionality of the tube. The following sizes are available in UHMW/PE. Please contact us for all other inquiries. Standard Tolerances (Bow tolerance is .1" per foot)
