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
