Catheter Liners & FEP Heat Shrink

Home / Products & Services / Catheter Liners & FEP Heat Shrink

PTFE etched thin-wall liners that set the standard in quality — produced with extrusion, in-line etching, and packaging in dedicated Class 10,000 / ISO 7 cleanroom facilities.

PTFE Etched Thin Wall Liners

Manufactured by Parker on state-of-the-art, best-in-class equipment with a fully automated process, these liners deliver high precision tolerances and an etched surface engineered for superior bonding performance in catheter construction.

Available Sizes

  • O.D. 0.055" to 0.190"
  • I.D. 0.053" to 0.187"
  • Wall thicknesses as small as 0.001" with tolerances of ±0.0005"

Medical FEP Heat Shrink Tubing

A full line of medical heat shrink designed specifically for use as an integral component of catheters and other devices where performance and design are critical.

  • Uniform recovery — significantly reduces wrinkles and twists
  • Reduced maximum elongation — constrained to roughly +5% (vs. up to 20% for typical FEP), limiting curling, pigtailing, marks, ridges, and thread effects
  • Faster recovery time — smooth transitions and uniform walls from one resin to the next in reflow applications

FEP Heat Shrinkable Tubing — Size Charts

Series HS1.3FEP and HS1.6FEP. Most of these sizes are stocked and ready to ship.

FAQ

Frequently Asked Questions

What are PTFE catheter liners used for?
PTFE catheter liners form the low-friction inner lumen of a catheter, giving devices a lubricious surface for smooth device passage and reliable reflow lamination.
How are your catheter liners manufactured?
They are PTFE etched thin-wall liners produced with extrusion and in-line etching, then packaged in dedicated Class 10,000 / ISO 7 cleanrooms for precision tolerances and superior bonding surfaces.
Do you also supply FEP heat shrink?
Yes. We supply FEP heat shrink tubing for reflowing, laminating, and encapsulating catheter components alongside PTFE liners.
