Adhesive Cloth Duct Tape K-flex K-FLEX® CLOTH DUCT 160 µm x 50 mm x 50 m, silver (grey)

K-flex K-FLEX® CLOTH DUCT adhesive cloth duct tape is a general-purpose sealing and repair tape designed for HVAC systems, insulation joints and temporary fixes. The tape has a 160 µm thick backing with cloth reinforcement and a pressure-sensitive adhesive that provides reliable adhesion to metal, plastic and insulated surfaces. Supplied in a 50 mm width and 50 m roll length in silver (grey), it is suitable for applications that require tear resistance and moderate conformability across irregular surfaces.

Advantages

The cloth backing delivers improved tear resistance and tensile strength compared with standard paper or thin polymer tapes, while the pressure-sensitive adhesive ensures quick tack and durable bond on a variety of surfaces. The 160 µm total thickness balances flexibility and mechanical protection, and the silver (grey) color offers a neutral appearance for HVAC ducts and exposed insulation areas. The 50 m roll length reduces the need for frequent roll changes on site.

Suitable for

• Sealing and repairing HVAC ducts and fittings
• Joining and patching insulation seams and joints
• Temporary surface protection and bundling of cables or materials
• General-purpose masking and holding during installation work

Key specifications

• Backing: cloth-reinforced material for tear resistance
• Adhesive type: pressure-sensitive adhesive suitable for metal, plastic and insulated surfaces
• Thickness: 160 µm total
• Width: 50 mm
• Roll length: 50 m
• Color: silver / grey

How to use

Ensure surfaces are clean, dry and free from dust, oil or loose particles before applying the tape. Measure and cut the required length, then press the tape firmly onto the surface, smoothing out any air pockets to ensure full contact. For seams and joints, overlap adjacent tape edges by a few millimetres to create a continuous seal. Remove slowly if repositioning is needed and apply new tape where necessary.

Usage recommendations

Store rolls in a dry environment away from direct sunlight and heat sources to preserve adhesive performance. For long-term or critical HVAC airtightness applications, verify compatibility with the specific insulation or substrate and consider using a permanent sealing solution if required.
