Key Features & Specifications

Exceptional Temperature Resistance

M23053/12 tubing operates in a temperature range of -55°C to +260°C (-67°F to +500°F), making it one of the most heat-resistant options available. It remains stable under extreme thermal cycling, preventing degradation or cracking over time.

High Shrink Ratio & Precise Fit

  • Shrink ratio: 1.7:1
  • Minimum shrink temperature: 340°F (170°C)
  • Full recovery temperature: 650°F (343°C)
  • Available inner diameters (ID): From 0.020" (before shrink) to 0.500" for various wire and component sizes.

This precise shrink capability allows for tight-fitting insulation and encapsulation, even in high-vibration environments.

Strain Relief & Mechanical Durability

Compared to standard polyolefin tubing, M23053/12 PTFE heat shrink tubing provides nearly 10x the tensile strength (up to 5,000 psi) while maintaining flexibility. It effectively absorbs mechanical stress and provides exceptional strain relief, making it ideal for aerospace and medical wiring harnesses where mechanical integrity is critical.

Unmatched Abrasion & Chemical Resistance

  • Abrasion resistance: M23053/12 PTFE tubing surpasses conventional materials like polyolefin by withstanding over 200,000 cycles in abrasion testing (Taber Test, CS-10 wheel, 500g load).
  • Chemical resistance: Fully inert against fuels, solvents, acids, and oils, preventing degradation in aerospace and chemical processing applications.
  • Non-stick & low-friction surface: Essential for bundling cables without adhesion or snagging.

Dielectric Strength & Electrical Insulation

M23053/12 tubing boasts a dielectric strength of up to 500 V/mil, making it an ideal insulator for high-voltage applications, preventing electrical arcing and short circuits.

Color Variants & Functional Benefits

M23053/12 PTFE heat shrink tubing is available in multiple colors, each offering distinct benefits for specific applications:

  • Clear: Allows for visual inspection of wires and components inside.
  • Black: UV-resistant, commonly used in aerospace and industrial applications.
  • Red, Blue, Yellow: Facilitates easy color-coded wiring identification in electrical harnesses.

Applications & Use Cases

Purchasing managers and engineers often encounter M23053/12 heat shrink tubing in technical specifications without fully understanding its advantages. Here’s where it excels:

  • Aerospace & Defense: Used in military-grade wiring insulation, high-temperature connectors, and fuel-resistant protection.
  • Medical Devices: Meets FDA & USP Class VI standards for sterilizable tubing in surgical instruments.
  • Oil & Gas: Protects sensor wiring and control systems in chemically harsh environments.
  • Industrial Equipment: Ideal for motor leads, control panels, and high-voltage insulation.
