Our StreamLiner™ series uses the latest advancements in extrusion technology to produce the most versatile and thinnest PTFE catheter liners yet. From soft and flexible to stiff and rigid, Zeus makes liners that deliver.

Our Thinnest Catheter Liners Yet

Flex your core capabilities with our extruded Sub-Lite-Wall® StreamLiner™ series, the latest in PTFE catheter liner technology. Maximize your ID or minimize your OD with our impressive array of thin walled catheter liners. These liners represent a new class of precision components that bring strength and flexibility to assist you with advancing new catheter designs.

As the thinnest extruded liner available, our PTFE Sub-Lite-Wall® StreamLiner™ series has set the standard for next generation catheter construction.

StreamLiner Family - Free Extruded and Over-The-WireStreamLiner™ OTW – VT, XT, and UT

StreamLiner™ Over-The-Wire (OTW) is our latest addition to the StreamLiner™ family. This new extruded over-wire offering is our thinnest, softest, and most flexible liner yet. Equivalent to a film cast PTFE liner, but with inherently more strength, StreamLiner™ OTW allows for new catheter designs that can navigate through the smallest and most tortuous vasculature to provide lifesaving therapies. Supplied in discrete lengths over silver plated copper (SPC), StreamLiner™ OTW provides a process ready liner that maximizes efficiency and reduces cost.

StreamLiner™ – VT and XT

Accommodating the most in-demand catheter sizes down to the smallest microcatheter, our free-extruded StreamLiner™ XT and VT sizes open up new designs that require optimum strength for delivery, but thinner walls to improve flexibility and tractability.

Revolutionizing Catheter Design

Catheters made with our StreamLiner™ series of PTFE liners allow for a reduced overall profile with greater lumen potential for finished catheter devices. The greater lumen afforded by StreamLiner’s™ thinner walls results in design options that can reduce deployment force for various intra-lumen catheter technologies or improve flexibility and kink resistance. The higher strength of StreamLiner™ PTFE catheter tubing translates into improved pushability and supports better tractability.

For microcatheter designs, the StreamLiner™ series allows greater access to the smallest vasculatures and most complex anatomies.


Improving Outcomes with Quality

With over 50 years of industry-leading experience in state-of-the-art polymer extrusion development and manufacturing, our customers look to us for greater advancements in catheter design aimed at improving patient care and clinical outcomes.

Quality is at the center of everything we do. With ISO as the basis of our quality system, we insure that products such as the StreamLiner™ series of PTFE liners will not only perform, but provide safety and reliability.

Reduce Delamination With Tie Layer

Zeus Tie Layer can be used to enhance bond strength between StreamLiner™ and the catheter jacket. Better bond strength equals better mechanical properties and performance for the finished catheter.

    Catheter Liners – As a thin-walled liner, StreamLiner™ series is perfect for the creation of both vascular and non-vascular catheters delivering a range of options.


    Biocompatible – PTFE has a long and proven history of safe use within the body. PTFE is USP Class VI certified.

    Chemical Resistance – PTFE’s fully fluorinated nature renders it inherently unreactive towards almost all commonly encountered chemicals and bodily fluids.

    Extremely Thin Walls – The StreamLiner™ series improves our already thinnest-in-class liner size to a new nominal wall thickness as low as 0.0004″ / 0.0102 mm (StreamLiner™ UT).

    Low Coefficient of Friction – PTFE has the lowest coefficient of friction of any polymer resin; this trait makes PTFE especially effective for micro-catheter design where lubricity and smoothness of surface are a necessity.

    Sterilizable – As a PTFE component, this product is sterilizable by ETO and autoclave (maximum working temperature of 260 °C / 500 °F).

    Strength and Flexibility – Our proprietary LoPro™ technology has allowed us to create the thinnest extruded over-the-wire liners yet with superior strength and comparable flexibility to film cast liners.

    Tight Tolerances – PTFE Sub-Lite-Wall® StreamLiner™ UT wall thickness tolerance is ± 0.0002″ (0.0051 mm) while XT and VT standard tolerance is ± 0.00025″ (0.00635 mm).
