MEZ-PTFE-Tape - 12x4 mm x 25 m

Secure, permanently airtight duct connections

In ductwork construction, leaks at flanges are a common source of cost: unnecessary air leakage, unnecessary rework on site and increased operating costs. Conventional sealing tapes often fail, particularly on uneven or damaged sealing surfaces. This situation leads to installation delays and customer complaints.

The MEZ‑PTFE‑TAPE – 12 x 4 mm, supplied on a 25 m roll, eliminates precisely these problems. The single-sided self-adhesive PTFE flat sealing tape, made from 100 % virgin expanded PTFE, provides an extremely reliable sealing solution, even with critical tolerances and minimal contact pressures.

Technical Highlights

• Material: 100 % virgin expanded PTFE, soft, highly flexible and creep-resistant
• Temperature resistance: -240 °C to +270 °C, up to +315 °C for short periods
• Chemical resistance: High resistance to media, pH 0–14
• Ageing-resistant: UV-, weather- and light-resistant
• Easy to install: Self-adhesive on one side to aid installation
• Sealing efficiency: Adapts to uneven and damaged surfaces; maintains pressure resistance once installed

These properties make MEZ-PTFE tape an ideal solution for static flange seals in air duct construction. This sealing tape is tested, reliable and designed for long-lasting connections with minimal leakage rates.

Key features

• Optimal sealing even on difficult surfaces
• High chemical and temperature resistance
• Simple, quick installation thanks to self-adhesive backing
• Resistant to ageing and therefore ideal for long-lasting systems
• Hygienic, physiologically safe

Additional features

• Predictable costing: Long-lasting sealing tape, resulting in fewer complaints and service calls
• Versatile application: PTFE tape for various duct systems and interfaces
• Excellent value for money: High-quality sealing tape reduces follow-up and installation costs
• Permanent sealing: No ageing, no hardening, no embrittlement
• Hygienic & stable: Physiologically safe, resistant to microorganisms
• Ideal for existing installations: Particularly suitable for repairs and leak optimisation

Installation

• Quick, clean installation: Self-adhesive, adapts to any surface
• No rework: Provides sealing for even uneven edges and damaged flanges
• Minimal downtime: Joint ready for load immediately, no retightening required
