This is a PEEK tube with an industry-leading inner diameter tolerance of ±30μm!
We manufacture and develop PEEK tubes with an industry-leading inner diameter tolerance of ±30μm. The concentricity (roundness: the difference between the center of the outer diameter and the center of the inner diameter) is also around 10μm. We continuously monitor the dimensions along the entire length of the tube using an online measuring device introduced in our production line. Currently, our tubes are mainly used for liquid chromatography (analytical instruments) delivery piping (outer diameter φ1.59mm, inner diameter φ0.13–1.00mm), but we also accept custom orders for various applications such as medical devices, electronic equipment, and semiconductors. We have a track record of sizes with an outer diameter of φ3mm or less, an inner diameter of 50μm or more, and a wall thickness of 100μm or more. As a special managed product, we also accept ultra-high precision items (inner diameter tolerance of ±10μm).

basic information
【Product Information】 ○ Ultra-thin PEEK Tube → With an inner diameter of φ2.6mm and a wall thickness of only 100μm (a ratio of inner diameter to wall thickness of 100:4), this ultra-thin PEEK tube is similar to a drinking straw. → For example, it can be used in limited spaces within precision small devices where insulation, mechanical strength, and sliding properties are required. ○ PEEK Tube for Liquid Chromatography Delivery Piping → PEEK tube with an inner diameter tolerance of ±30μm. → Used for delivery piping in liquid chromatography (analytical instruments). → Made from PEEK, which boasts the highest level of mechanical strength and chemical resistance among resins. ○ Special PEEK Tube with Unique Inner and Outer Diameters for Liquid Chromatography Delivery Piping → Starting production of PEEK tubes with an outer diameter of 1/16" and a minimum inner diameter of φ0.13mm, which is half of that, with an inner diameter of 65μm (outer diameter is 1/16"). → Inner diameter tolerance is ±15μm. ○ Sample Loop Processing → Production of sample loops that do not require bundling. ○ Large Capacity Sample Loop Processing → Coiling of PEEK tubes over 2m for the 2ml type and over 6m for the 5ml type. ● For more details, please visit our website.
