Adhesive Cloth Tape K-flex K-FLEX® CLOTH DUCT 160 µm × 50 mm × 50 m – blue

K-flex K-FLEX® CLOTH DUCT is a blue adhesive cloth tape with a thickness of 160 µm, a width of 50 mm and a roll length of 50 m. The product is designed for ducting, sealing insulation joints and protecting surfaces during HVAC and construction work. The cloth backing combines flexibility and tear resistance, while the pressure-sensitive adhesive provides reliable bonding to common insulation materials, metal ducts and many construction surfaces.

Advantages

The tape offers good conformability around irregular shapes and bends, allowing neat sealing of seams and joints. Its cloth construction provides dimensional stability and resistance to tearing during application, and the adhesive backing ensures quick stick and hold on a variety of substrates. The blue color aids visual identification and neat laying in installation work, and the 50 m roll reduces the need for frequent replacements on job sites.

Suitable for

• Sealing insulation joints on pipes and ducts
• Bundling and temporary repair of HVAC components
• Surface protection during installation and maintenance
• Masking and securing materials on construction sites

Key specifications

• Backing material: cloth fabric with high conformability
• Adhesive type: pressure-sensitive adhesive for immediate tack
• Thickness: 160 µm
• Width: 50 mm
• Length: 50 m per roll
• Color: blue for visual identification
• Mechanical properties: tear-resistant and flexible

How to use

Ensure surfaces are dry, clean and free from dust, oil and loose particles before application. Cut the required length and apply the tape with even pressure, smoothing it down to ensure full contact with the substrate and to remove air pockets. For seams and joints, overlap adjacent passes as needed to create a continuous seal. On curved or irregular surfaces, apply progressively and press the tape into place to conform to the profile.

Usage recommendations

Store rolls in a cool, dry place away from direct sunlight and excessive heat. For best adhesion, apply at moderate temperatures and avoid stretching the tape excessively during application. Use the tape for indoor and sheltered outdoor applications where mechanical protection or long-term exposure to weather is not required; for prolonged outdoor exposure or chemically aggressive environments, confirm compatibility with the substrate and consider specialized sealing materials.
