HellermannTyton SBPTFE4 NA-PTFE spirálcső, 4 mm, PTFE, natúr

In control cabinets and automated production lines, engineers need a cable protection that withstands aggressive chemicals, extreme heat, and constant flexing. The HellermannTyton SBPTFE4 spiral wrap answers that demand: a self-extinguishing PTFE sleeve that bundles and shields cables in temperatures from -60 °C to 260 °C, with short-term peaks up to 350 °C.

Key specifications

• Material: Polytetrafluoroethylene (PTFE), grade NA-PTFE
• Nominal diameter: 4 mm
• Colour: natural
• Continuous operating temperature: -60 °C to 260 °C
• Short-term operating temperature: 350 °C
• Flame retardancy: self-extinguishing
• Chemical resistance: excellent
• UV resistance: excellent
• Abrasion resistance: high
• Dielectric strength: high
• Halogen-free: yes

Why choose it

PTFE offers inherent flame retardancy and outstanding chemical inertness, making this spiral wrap ideal for harsh environments where PVC or nylon would degrade. Its high flexibility allows easy installation around tight bends without cracking, and the natural colour keeps the bundle visually neutral.

Ideal use cases

• Protecting cable harnesses in chemical plants and laboratories
• Bundling wires in high-temperature equipment such as ovens or heaters
• Organising cables in UV-exposed outdoor installations
• Insulating and shielding sensitive signal lines in electronics

Good to know

The spiral design permits cables to be inserted or removed at any point along the wrap, simplifying maintenance. PTFE's low friction surface also reduces abrasion between cables.
