## Long description

Armacell K-28/20 polyurethane elbow fitting is designed to provide thermal insulation and mechanical protection at pipe bends. Sized to fit 28/20 dimensions, this elbow section connects two insulated pipe runs while maintaining continuous insulating coverage. Manufactured from closed-cell polyurethane foam, it offers a balance of low weight and impact resistance for installations in HVAC systems, domestic plumbing, and industrial piping networks.
Advantages
The K-28/20 elbow delivers continuous thermal protection across curved pipe runs, reducing heat loss and helping to prevent condensation. Its closed-cell polyurethane construction resists moisture absorption and provides mechanical protection against minor impacts. The lightweight form factor simplifies handling and speeds up installation while maintaining dimensional stability in typical building and industrial environments.
Suitable for
 Thermal insulation of pipe bends in HVAC systems
 Insulation and protection of plumbing bends in residential and commercial buildings
 Pipe elbow protection in light industrial and process piping
Key specifications
 Material: closed-cell polyurethane foam
 Intended pipe size: 28/20 dimensions
 Function: thermal insulation and mechanical protection for elbows
 Weight: lightweight construction for easy handling
 Moisture behaviour: low absorption due to closed-cell structure
How to use
Position the elbow fitting over the pipe bend so that it mates with adjacent straight insulation sections, ensuring a snug fit along the pipe surface. Where necessary, cut or trim the ends for a tight joint with adjoining insulation pieces. Secure seams and joints with compatible adhesive or sealing tape recommended for polyurethane insulation to preserve thermal continuity and prevent moisture ingress. Follow standard safety and installation practices for working with pipe insulation materials.
Usage recommendations
For optimal performance, store the fittings in a dry environment prior to installation and avoid prolonged exposure to direct sunlight. Use adhesives and tapes compatible with polyurethane foam and inspect joints after installation to ensure continuous coverage and sealing at bends.
