## Summary description

SILVERLINE Rund-Flat 90 is a PVC round-to-flat duct adapter in white, designed to connect Ø150 mm round ducts to 89 mm flat ducts with a 90° bend. Supplied as a single piece per pack, it suits ventilation and extraction systems requiring a compact directional change and simple, durable plastic connection.

## Long description

SILVERLINE Silverline Rund-Flat 90 PVC adapter white Ø150/89 x 222 mm is a one-piece plastic duct transition for ventilation and extraction systems. It connects a 150 mm round duct to an 89 mm flat duct while redirecting airflow by 90° in a compact footprint. The adapter is injection-molded from white PVC and supplied as a single unit per pack, intended for installations where a durable, low-cost directional change and compatible mating to standard round and flat ducts is required.
Advantages
The adapter provides a compact 90° change of direction with an integrated transition between round and flat profiles, reducing the need for multiple components. Made of PVC, it resists moisture and typical condensate in ventilation ducts and is lightweight for easy handling. The single-piece design simplifies installation and reduces potential leak points compared with multi-part assemblies.
Suitable for
 Residential and light-commercial ventilation systems
 Kitchen extraction and range hood ducting
 Connecting standard Ø150 mm round ducts to 89 mm flat ducts in restricted spaces
 Retrofit projects where a compact 90° transition is needed
When it may not be suitable
This PVC adapter is not designed for high-temperature flue gases, direct exhaust from combustion appliances, or installations requiring fire-resisting ductwork. It is intended for air-moving ventilation and extraction only and may not be suitable where structural rigidity or heavy mechanical loads are required.
Key specifications
 Material: PVC (polyvinyl chloride), white finish
 Round inlet diameter: 150 mm
 Flat outlet nominal width: 89 mm
 Overall axial length: 222 mm
 Bend angle: 90 degrees
 Single-piece construction, injection-molded
How to use
Measure and mark the round and flat duct runs, ensuring compatible Ø150 round and 89 mm flat profiles. Push the round duct into the round inlet until seated, and insert the flat duct onto the flat outlet; use appropriate clamps, banding, or duct tape to secure joints and prevent air leakage. Support the assembly as needed to avoid strain on joints and maintain the designed airflow direction. For sealed systems, apply a suitable duct sealant around joints following manufacturer instructions.
What to consider before purchase
 Confirm duct diameters and profiles (Ø150 round to 89 mm flat) match your system
 Verify that PVC material and a 90° bend are acceptable for your application (temperature and regulatory requirements)
 Check available clearance and axial length (222 mm) to ensure fit in the intended location
 Plan mounting or support to avoid mechanical stress on the adapter and connected ducts
Usage recommendations
Use the adapter in low- to moderate-temperature ventilation and extraction applications only; secure joints with clamps or tape and provide mechanical support to maintain airtight connections and reliable airflow. Avoid exposure to direct heat sources or corrosive chemicals to preserve material integrity.
