Polyurethane liner with a tapered wall, designed for patients of all activity levels.
  • Made of skin-friendly polyurethane to ensure even pressure distribution and high shock absorption
  • Wall thickness of 6 mm in the distal area (up to 10 cm) tapers to 3 mm in the proximal direction for additional protection of the residual limb
  • Floating effect maintains a precise, comfortable fit
  • Available with Skinguard antibacterial additive
  • Available with (6Y523) or without (6Y522) a textile cover
  • Suitable for all residual limb types, especially sensitive, bony, and/or scarred residual limbs
  • Ideal for use with an exhaust valve and sealing sleeve or with the Harmony vacuum volume management system
How to measure for liner size: Measure the residual limb circumference 4 cm above the distal end of the residual limb and select the liner size corresponding to this measurement or the next smaller size.

Serial number location:
To find serial number, invert liner inside out and look at the distal end for the laser etched information. Talc powder rubbed on etching may help to read.
