## Long description

The SpiroFlex RED250/200-OC is a professional-grade galvanized steel nipple reducer engineered for seamless integration into ventilation and HVAC systems. This component is specifically designed to facilitate a precise transition between circular air ducts with diameters of 250 mm and 200 mm, ensuring structural integrity and consistent airflow throughout the ductwork.
Advantages
Constructed from high-quality galvanized steel, this nipple reducer offers exceptional resistance to corrosion and mechanical wear, making it a reliable choice for long-term ventilation projects. Its precise manufacturing ensures a tight, secure fit within standard spiral ducts, which minimizes air leakage and reduces energy loss. The smooth internal surface promotes efficient air movement, helping to maintain optimal system performance and quiet operation in both residential and commercial environments.
Suitable for
Connecting ventilation ducts of different diameters
Residential HVAC system installations
Industrial air handling and exhaust systems
Retrofitting or expanding existing ductwork
This reducer may not be suitable for applications involving highly corrosive chemical vapors or extreme temperature environments that exceed the thermal limits of galvanized steel. It is also not intended for use in high-pressure pneumatic conveying systems where specialized heavy-duty fittings are required.

How to use

It is recommended to secure the joints using self-tapping screws or rivets and to seal the connections with professional-grade duct tape or sealant to prevent air leakage and ensure system airtightness.
What to consider before purchase
Verify the exact diameter requirements of your existing ductwork
Ensure the nipple connection type matches your current duct configuration
