10% PEEK filled PTFE tube supplier

As a dedicated 10% PEEK filled PTFE tube supplier, we engineer tubing that blends the low friction of PTFE with the load-bearing strength of PEEK. This filled compound solves a common problem in sealing and bearing systems: standard PTFE deforms under load or wears too quickly, while unfilled PEEK lacks the lubricity needed for dry-running contact. Our catalog includes 10% PEEK PTFE tube for high speed service for rotary and linear motion, PEEK reinforced PTFE tubing for structural support, high wear PEEK PTFE tube for abrasive environments, and PEEK PTFE compound tube for tailored filler loadings and custom blends. Unlike glass-filled or carbon-filled PTFE, the 10% PEEK filler does not aggressively abrade mating metal surfaces, which helps extend the service life of shafts, sleeves, and housings. The material also retains excellent chemical resistance and low moisture absorption, making it suitable for wet or chemically aggressive service conditions. In high-speed pumping, valve actuation, and precision instrumentation, the tubing maintains dimensional stability under fluctuating temperatures and mechanical loads. The filled PTFE also shows lower permeability than unfilled PTFE, reducing leakage in gas handling and vacuum systems. Our manufacturing process uses isostatic molding and ram extrusion to achieve uniform filler distribution and consistent density through the tube wall. This results in predictable machining behavior, reduced scrap rates, and reliable part-to-part repeatability for OEMs and maintenance teams.

The 10% PEEK filled PTFE tube is stocked in common diameters and wall thicknesses, and can be cut to length or machined into finished components without special equipment. Because PEEK is a high-temperature thermoplastic, the compound keeps its mechanical integrity across a broader thermal window than many filled PTFE grades. The material machines cleanly with standard carbide tools, and the low internal stress of the extruded tube reduces the risk of cracking during deep boring or thin-wall finishing operations. Primary applications include high-speed rotary seals, valve stem packings, compressor wear rings, pump bushings, and electrical insulators that require both dimensional stability and low friction.
