Niuli HVAC Cable Ties are extra-long, heavy-duty PA66 ties designed for securing flexible air ducts, air connectors and insulation materials. Compared with standard cable ties, the HVAC series combines a 9 mm wide strap, lengths up to 1200 mm and 175 lb / 80 kg minimum loop tensile strength, making it suitable for large-diameter duct applications.
Flexible HVAC ducts often require a fastener that can wrap around a large diameter while maintaining reliable clamping force. Niuli HVAC Cable Ties are available in multiple extra-long sizes, with maximum bundle diameters up to approximately 340 mm, depending on model.
The 9 mm and 12 mm wide strap provides a larger contact area than standard narrow cable ties and is designed for demanding HVAC installation work. The self-locking one-piece construction allows installers to wrap, tighten and secure the duct quickly.
Ideal for:
Manufactured from PA66, the series provides a minimum loop tensile strength of 175 lb / 80 kg. Recommended operating temperature: -40°C to +85°C. For North American HVAC projects requiring UL 181B-C, the exact product model and certification coverage should be confirmed before ordering.
Multiple extra-long sizes are available. Free samples can be provided for checking duct diameter, fastening strength and installation fit before bulk purchasing.

They are designed mainly for securing flexible air ducts, air connectors and insulation materials in HVAC installations.
Flexible ducts often have large outside diameters, so extra-long ties are required to wrap around the duct and fitting.
The current HVAC series is rated at 175 lb / 80 kg minimum loop tensile strength.
Niuli offers 9 mm wide HVAC ties from 800 mm to 1200 mm, covering bundle diameters up to approximately 340 mm.
UL 181B-C coverage depends on the exact product model. Please confirm the required certification with us before ordering.
Send us your required size, tensile strength, application, operating temperature and installation environment. Our team can recommend a suitable cable tie specification for your project.
Soft, adjustable and reusable cable ties designed for fiber optic, network, data and other sensitive cables that require frequent access or lower bundling pressure.
Designed for Low-Profile Fastening: Niuli In-Line Cable Ties feature a 180° parallel-entry locking design that creates a flatter profile than conventional cable ties. The compact head and smooth outward-facing surface make them especially suitable for applications where protruding cable tie heads may snag, interfere with surrounding materials or create uncomfortable contact.
1.Features: The Handcuffs like the connection of two cable ties, which can bind or fix two pipes or cables at the same time, also suitable for police, security guard or where someone need to be restrained.
2.Material：UL Approved Nylon 66.
3.Flammability: UL 94V-2.
4.Installation temperature：-10℃ to 85℃.
5.Working temperature：-40℃ to 85℃.
6.Color: Natural (white), Black, other colors are available as requested.
7.Certificates: UL, CE, RoHS, REACH, SGS.
