Our Thinnest Catheter Liners Yet

Flex your core capabilities with the Sub-Lite-Wall® StreamLiner™ series, the latest in PTFE catheter liner technology. Featuring an impressive array of thin wall and minimal ID/OD catheter liner options, these liners represent a new class of precision components that bring strength and flexibility for more advanced catheter designs.

PTFE Sub-Lite-Wall® StreamLiner™ XT and VT

Accommodating the most in-demand catheter sizes down to the smallest microcatheter, our new PTFE Sub-Lite-Wall® StreamLiner™ series lets engineers and clinicians explore new delivery systems and improve patient care.

StreamLiner™ Series

StreamLiner™ XT offers a maximum wall thickness of 0.00075″ (0.01905 mm) and an ID range of 0.004″ – 0.040″ (0.102 – 1.016 mm) unetched, and 0.013″ – 0.040″ (0.330 – 1.016 mm) etched.

As a thin-walled liner, StreamLiner™ XT is the soon-to-be standard for microcatheter construction to support the next generation of minimally invasive therapies.

StreamLiner™ VT is slightly larger and provides a maximum wall thickness of 0.001″ (0.025 mm) with an ID range of 0.004″ – 0.120″ (0.102 – 3.048 mm).

For larger and more common sizes, StreamLiner™ VT fills this demand and provides clinicians with a new standard of strength and flexibility for catheter-based therapies.

Revolutionizing Catheter Design

Catheters made with StreamLiner™ series 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 reduced deployment force for various intra-lumen catheter technologies. The higher strength of StreamLiner™ PTFE catheter tubing translates into improved pushability and supports better tractability.

For microcatheter design, StreamLiner™ XT allows greater access to the smallest vasculatures and most tortuous anatomies.

Improving Outcomes with Quality

Leveraging 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 for the finished catheter device.

    Catheter Liners – As a thin-walled liner, this product is perfect for the creation of micro-sized catheters for a range of delivery and application 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 maximum wall thickness of 0.00075″ / 0.01905 mm (StreamLiner™ XT).

    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 liners yet but with superior strength and comparable flexibility compared to dip-coated liners.

    Tight Tolerances – Sub-Lite-Wall® StreamLiner™ XT standard ID tolerance is ± 0.0005″ (0.0127 mm) while VT ID standard tolerance can be as low as ± 0.001″ (0.025 mm) for ID’s greater than 0.100″ (2.54 mm).
