    Custom Fillers – Providing greater specialization for your application, fillers allow the properties of base polymer tubing to be further tailored. Common options available include bismuth and barium for added visibility under fluoroscopy and x-ray, carbon fiber to improve crush resistance and electrical dissipation, and glass to enhance bonding and reduce longitudinal change.

    Custom Profiles – Providing square, rectangular, and custom shapes, we offer a range of extrusion options for specialized applications. We strive to produce these tight-tolerance custom profiles to the highest standards.

    Engineered Surface Tubing – For strain-free movement, engineered surface tubing provides unique profiles and micro-structured surface channels which decrease friction allowing easier fiber optic manipulation and handling.

    Heat Shrinks – We can help you select the ideal heat shrinkable material to encapsulate and protect your fiber optic housings, cables, and connectors from elevated temperatures and moisture. Our heat shrinks are available in shrink ratios up to 4:1 with temperature tolerances reaching 500 °F (260 °C).

    Multi-Lumen – Zeus has the ability to extrude round tubes with separate channels, or “passages,” that run the length of the tubing so that multiple optical fibers can be placed within a single outside diameter.

    Polymer Coating – We make custom coatings to protect your fiber optics from environmental extremes including temperature (high and low), pressure, radiation, and moisture absorption. These coatings also provide chemical resistance and impart added structural support.

    Spiral Cut – This expandable tubing secures your fiber optics in bundles and provides added abrasion and temperature resistance. The expandable nature of this product allows the removal of leads anywhere along the wrapped fiber bundle. This specialty tubing also allows sensors to come in contact with oils or other liquids while remaining protected from physical trauma.

    Tubing and Sheathing – Also called furcation tubing, these products are commonly used in fiber optics to protect and bundle these fragile communication devices. The high lubricity of these polymer tubings and sleeves easily slides over optical fibers without damaging them and decreases strain and friction. These options are available in standard and custom sizes and tolerances. These polymer coverings are also available with assembly aids to facilitate fiber insertion into the sheathing or tubing.
