Aerospace, automotive, and many other industries require tubing that can maneuver around tight and cramped spaces in critical environments. Zeus convoluted tubing offers low friction, abrasion protection, flexibility, and is available in both standard and extra flex options.

Zeus brings a diverse range of flexible convoluted products to industries including electrical and electronics, aerospace, analytical, defense, chemical, automotive, medical, and much more. Convoluted tubing is used as a protective and flexible conduit for wires and optical fibers in critical areas that demand high performance tubing. We are capable of producing high volumes of convoluted tubing in a range of flex sizes.

Zeus can produce convoluted tubing from a wide variety of resins, including PTFE, FEP, and ETFE; other resins may also be possible.

Contact us or call 1-800-526-3842 toll-free in the US to learn more about resin possibilities for your convoluted tubing solution. You can also reach us internationally at +1-803-268-9500.

Made to Order

Zeus can customize your convoluted tubing in a variety of resins and configurations. Simply supply us with your design parameters such as convolutes per inch, final wall thickness, major inside and outside diameters, and one of our polymer extrusion experts will contact you with a quote.

In addition to these specialized options, we also offer custom colors and value-add services for your tubing including longitudinal slitting, drilled holes, and cut-to-length sizing. ETFE can be sourced with flares, flanges, draw downs, drilled holes, or a combination of these services. Custom profiles and multi-lumen tubing may also be available depending upon your material choice.

  • APPLICATIONS

    Wire Harness and Cabling – Our convoluted tubing products provide a superior solution as an insulator to protect electrical wire harnesses, cables, and fiber optics from temperature extremes, harsh environments, and electrical interference. The flexible nature of this tubing provides an adaptable conduit to fit securely within limited or tight spaces while giving engineers increased freedom during the design process.

    Zeus convoluted tubing is already widely used in the aerospace, automotive, fiber optics, and oil and gas industries. Our convoluted tubing also has widespread use in areas such as critical fluid transfer and medical arenas as well as in general industrial manufacturing.

  • KEY PROPERTIES

    Abrasion Resistant – Zeus convoluted tubing products are highly resistant to abrasion making them an excellent choice for protection of your wires and cables from trauma.

    Chemically Resistant – Our convoluted tubing is highly chemically resistant to nearly all commonly encountered solvents and hydrocarbons; this makes our tubing suited to a broad spectrum of application environments and maximizes your tubing options.

    Durable – When you purchase convoluted tubing from Zeus, you can be assured of value. Our convoluted tubings are highly durable providing long life and protection for your cabling and wire harnessing needs.

    Excellent Thermal Properties – The resins used to produce our tubings result in products with high working temperatures which can be utilized in a range of harsh environments.

    Flame Resistant – Zeus convoluted tubings possess a UL 94 V-0 flammability rating and thus do not burn readily. These products are well-adapted to conditions involving exposure to heat while also providing some degree of warning if exposed to flame.

    Longer Lengths – Our processing enables us to create convoluted tubing with extended tubing runs during melt processing to produce longer lengths. This means that you can encapsulate long cable and wire runs in a continuous manner without having to apply or join multiple tubing sections.
