Zeus Sub-Lite-Wall™ heat shrink tubing has been engineered to produce nominal wall thicknesses 0.005″ (0.127 mm) and below, down to 0.001″ (0.025 mm), with tolerances of ± 0.0005″ (0.0127 mm) available in most sizes. This super-thin-walled heat shrink fills a critical need for our customers demanding thinner walls for their specialized applications.
Though primarily extruded in PTFE, we also offer our Sub-Lite-Wall™ heat shrink in FEP, PFA, and PEEK for a broad spectrum of applications. For PTFE, this highly versatile polymer became the gold standard for tubing options requiring high lubricity, temperature endurance, and precision tolerances. As a heat shrink, PTFE has a high presence in areas ranging from medical devices, analytical and laboratory equipment, chemical environments, and industrial equipment.
With the lowest coefficient of friction of any polymer, PTFE Sub-Lite-Wall™ heat shrink is easy to wipe clean and not prone to staining. This heat shrink is flame resistant and imparts excellent mechanical strength to covered components for its wall thickness compared to other polymer coverings.
Please note that the sizes listed in our Sub-Lite-Wall™ heat shrink sizing guide are based upon PTFE. Size options vary for FEP, PFA, PEEK, and other fluoropolymer resins for Sub-Lite-Wall™ tubing.

Catheter Lead Delivery – Our Sub-Lite-Wall™ products are developed to support the critical functions and construction for multiple catheter types, from guide sheaths for varying flexibility and strength down to the smallest microcatheter.
Batteries – Zeus heat shrinks are a popular choice where efficiency and dielectric strength are most important for battery coverings. Sub-Lite Wall™ heat shrink removes the waste and inconsistency of tape and can be installed quicker and easier than wrapping.
Diagnostic – When visualization is of primary importance, such as in brain angiography, our catheter components, such as our PTFE heat shrink inner catheter liners, are chemically unreactive not only with body components but also with dyes which are commonly used for contrast material. Zeus PTFE Sub-Lite-Wall™ heat shrink can withstand a range of sterilization protocols to minimize the risk of catheter-associated infections.
Endoscopy – Sub-Lite-Wall™ inner liners for catheters provide the utmost in lubricity, electrical performance, chemical resistance, and are UV sterilizable. Because of their extremely low coefficient of friction, PTFE Sub-Lite Wall™ liners are ideal as inner walls through which instruments can be passed.
Sensors – Heat shrink options are a convenient and efficient way to protect and insulate valuable sensors. Zeus Sub-Lite-Wall™ heat shrink provides multiple customization options for your exact operating conditions, helping to extended the life of your sensor components.
Biocompatibility – PTFE has a proven history of use within medical devices. For more information on PTFE’s biocompatibility, contact us today.
Broad Working Temperature Range – PTFE has an extended service temperature range, allowing this heat shrink to be used in cryogenic temperatures up to 500 °F (260 °C).
Chemical Resistance – PTFE is resistant to all common solvents, including acids, bases, and hydrocarbons.
Easy to Clean – Because of its highly lubricious nature, PTFE’s surface is inherently non-stick, making the Sub-Lite-Wall™ heat shrink easy to wipe clean.
Excellent Dielectric Strength – Exceptional dielectric strength prevents electrical interference coming from, or getting into, your covered components.
Flame Resistant – In addition to its temperature tolerance, PTFE Sub-Lite-Wall™ heat shrink is highly flame-resistant.
Low Coefficient of Friction – PTFE has the lowest coefficient of friction of any polymer.
Low Extractables – PTFE has an extremely low level of chemical extractables, minimizing the chance of substances leaching into your materials from the heat shrink.
Mechanical Resistance – After recovery, PTFE Sub-Lite-Wall™ imparts superior strength and mechanical toughness to your covered components.
Sterilizable – PTFE Sub-Lite-Wall™ can hold up to EtO and autoclave sterilizations.
