SpiroFlex duct pipe black 150 mm, length 0.25 m, model SX-WCZ150R0,25

Rigid black SpiroFlex duct pipe with a nominal diameter of 150 mm and a length of 0.25 m. Designed as a short, sturdy section for ventilation and air distribution systems, this 150 mm duct segment serves as a compact connector or replacement piece within indoor HVAC assemblies and air handling units. The smooth exterior and consistent circular profile support straightforward integration into existing circular ductwork where a short run or repair is required.

Advantages

The SpiroFlex 150 mm duct pipe offers a rigid construction that maintains shape under airflow and moderate handling during installation. Its black finish provides a discreet appearance for indoor installations and helps conceal minor surface marks. The nominal 150 mm diameter matches common circular duct standards, making it compatible with standard clamps and sealing methods for reliable airflow connections. The short 0.25 m length makes the component convenient as a connector, spacer, or replacement segment in tight or compact duct layouts.

Suitable for

• Joining or repairing circular ventilation ducts with 150 mm diameter
• Short duct runs or compact connectors in residential and commercial HVAC systems
• Integration with air handling units and indoor ventilation assemblies
• Replacement segments during maintenance or retrofitting of ductwork

How to use

Measure and confirm the existing duct diameter and required insertion depth before installation. Prepare mating duct ends by cleaning and, if necessary, deburring to ensure a flush connection. Slide the SpiroFlex duct pipe into or onto the adjoining duct sections, align the ends to maintain uninterrupted airflow, and secure the joints using appropriate clamps, brackets, or sealing tape designed for ventilation systems. Verify airflow and check for leaks after installation, adjusting seals as required.

Usage recommendations

For best performance, use compatible clamps and HVAC sealing materials to ensure airtight connections. Avoid exposure to direct outdoor weathering and long-term UV exposure since the component is intended for indoor ductwork. When replacing sections in active systems, follow standard safety procedures and, if necessary, consult HVAC installation guidelines to maintain system balance and efficiency.
