HellermannTyton TFE2-10-1220-PTFE-CL PTFE Heat Shrink Tubing 2:1 Transparent 4.85mm x 2.85mm x 1.22m

This PTFE heat shrink tubing stands out with its exceptional temperature range and chemical inertness, making it suitable for demanding environments where standard polyolefin tubing would fail. The transparent sleeve allows visual inspection of the covered component, while the 2:1 shrink ratio ensures a snug fit over irregular shapes.

Highlights

• Made from PTFE (Polytetrafluoroethylene) for superior chemical and UV resistance
• Operating temperature from -65 °C to +260 °C
• Transparent for easy inspection of underlying connections
• Non-flammable and halogen-free
• Meets MIL-I-23053/12 and AMS-DTL-23053/12 standards

In daily use

With an expanded inner diameter of 4.85 mm and a recovered diameter of 2.85 mm, this tubing is ideal for insulating wires, splices, and components in aerospace, automotive, and chemical processing applications. Its high dielectric strength (>20 kV/mm) provides reliable electrical insulation even at elevated temperatures. The 1.22 m length offers ample material for multiple installations.
