## Summary description

Niczuk Obejma DUO 11/4 BK is a hose clamp designed for securing pipes and hoses with a clamping diameter range of 39–44 mm. The DUO construction provides a dual-contact grip for reliable fastening. Suitable for plumbing, HVAC and automotive applications where a robust adjustable clamp is needed to prevent leaks and ensure secure hose connections.

## Long description

Niczuk Obejma DUO 11/4 BK Ø39–44 mm is a metal hose clamp engineered to secure hoses and pipes with diameters from 39 to 44 mm. The DUO construction uses two contact surfaces to distribute clamping pressure evenly, reducing the risk of deformation and improving sealing performance. The clamp is adjustable and suitable for repeated assembly and disassembly where a consistent, reliable connection is required.
Advantages
The dual-contact DUO design provides stable, uniform pressure around the hose circumference, minimizing local compression and potential leaks. Its adjustable range covers common medium-diameter hoses and plumbing connections, offering flexibility during installation. Constructed from corrosion-resistant materials with a robust drive mechanism, the clamp maintains clamping force under vibration and thermal changes typical for plumbing, HVAC and automotive environments.
Suitable for
Securing flexible hoses in plumbing systems
Connections in heating, ventilation and air conditioning installations
Automotive hose connections such as coolant or intake lines
Temporary or permanent repairs where adjustable clamping is needed
Key specifications
Clamping diameter range: 39–44 mm
DUO dual-contact construction for even pressure distribution
Adjustable tightening mechanism for repeated use
Material: corrosion-resistant metal components suitable for wet and variable-temperature conditions
Finish: black coating for additional surface protection
How to use
Position the clamp around the hose and the mating pipe so the sealing surfaces align with the hose end. Tighten the drive mechanism gradually until the clamp contacts the hose uniformly and the connection is firm; avoid over-tightening to prevent hose damage. For removal, loosen the drive mechanism until the clamp can be slid off. Inspect the sealed joint after installation and retighten if minor settling occurs during initial use.
Usage recommendations
Use appropriate hand tools that match the clamp drive type to ensure controlled torque. For applications in corrosive environments, periodically inspect the clamp and replace it if signs of corrosion or loss of clamping force appear. When used on soft or thin-walled hoses, monitor for indentations and adjust tightening accordingly to maintain a secure seal without damaging the hose.
