Flexible EPE Foam Duct Bend 90° UBBINK AERFOAM EPE 125 BEND 90, 125 mm diameter

UBBINK AERFOAM EPE 125 BEND 90 is a 90° flexible bend for 125 mm ventilation ducting, manufactured from expanded polyethylene (EPE) foam. The component is intended for low-pressure air distribution in residential and light-commercial ventilation and HVAC systems. Its lightweight, compressible construction allows easy alignment and connection between straight duct sections while providing basic thermal insulation and sound attenuation properties compared with rigid duct fittings.

Advantages

The EPE foam construction delivers a combination of flexibility and dimensional stability that simplifies installation in confined or irregular spaces. The bend reduces airborne noise transmission through the duct run and offers a thermal barrier that helps limit heat loss or gain in low-pressure systems. Its lightweight design decreases handling effort and reduces the need for additional support compared with heavier materials, while the resilient material tolerates minor impacts and repeated disassembly.

Suitable for

• Residential ventilation systems (bathrooms, kitchens, living areas)
• Light-commercial HVAC installations where low-pressure distribution is used
• Retrofit projects requiring flexible connections and limited access
• Applications needing basic thermal insulation and reduced ductborne noise

Key specifications

• Bend angle: 90°
• Nominal duct diameter: 125 mm
• Material: expanded polyethylene (EPE) foam
• Suitable for low-pressure air distribution
• Lightweight and flexible construction
• Provides thermal insulation and sound attenuation compared with uninsulated rigid ducts

How to use

Install the 90° bend by aligning it with the mating 125 mm duct sections and securing connections according to the ventilation system design. The flexible EPE material permits small compressions and adjustments for a tight fit; use appropriate clamps, tape, or collars designed for foam duct components to ensure an airtight joint. Verify that the bend orientation matches the intended airflow direction and avoid sharp kinks or compressions that could restrict flow. Follow local building codes and HVAC installation guidelines for support intervals, sealing, and fire-safety requirements.

Usage recommendations

For durable performance, avoid exposing the EPE bend to open flames, high temperatures, or aggressive chemicals. Use compatible duct seals and mechanical fasteners suited for foam materials, and inspect joints after initial system start-up to confirm airtight connections and unobstructed airflow.
