K-FLEX Rigid 90° Insulation Elbow for HVAC & Industrial Pipes
£7.75
K‑FLEX PU Elbow is a factory‑formed rigid polyurethane (PUR) elbow designed to provide continuous thermal insulation across pipe bends. It ensures uniform thickness, reliable performance and professional finish when insulating directional changes in industrial and HVAC pipe systems.
Key Features & Benefits
- Precision‑moulded 90° elbow ensures consistent insulation around bends.
- Matches K‑FLEX PU pipe section thicknesses for seamless system integration.
- Low thermal conductivity: λ40°C ≈ 0.0349 W/m·K
- Temperature suitability up to +110°C.
- Rigid closed‑cell PUR offers durability and dimensional stability.
Applications
- HVAC and mechanical pipe bends
- Industrial process pipelines requiring insulated changes of direction
- Chilled water, heating and hot water systems
- OEM fabrication for insulated assemblies
