## Summary description

K-flex K-FLEX® PU insulation elbow with PVC jacket, size 20 x 28, designed for thermal insulation of pipe bends. Consists of polyurethane (PU) core and protective PVC outer covering to reduce heat loss and provide mechanical protection. Suitable for use in heating, ventilation and air-conditioning (HVAC) systems and industrial piping where insulated elbows are required.

## Long description

K-flex K-FLEX® PU insulation elbow with PVC jacket, size 20 x 28, is a pre-formed thermal insulation component engineered for insulating pipe bends in heating, ventilation and air-conditioning (HVAC) systems and industrial piping. The elbow combines a closed-cell polyurethane (PU) foam core with a protective PVC outer jacket to reduce thermal losses, limit condensation risk and provide basic mechanical protection for elbow sections where continuity of insulation is required.
Advantages
The PU foam core offers low thermal conductivity and a closed-cell structure that resists moisture absorption, while the PVC jacket delivers abrasion resistance and easy cleaning. Pre-formed shape ensures uniform thickness and fast installation at elbows without the need for extensive on-site shaping. The product is dimensioned for compact bend sections and is compatible with standard pipe insulation systems to maintain continuous thermal performance across fittings.
Suitable for
 Thermal insulation of pipe bends in HVAC systems
 Insulated elbows in hot and chilled water distribution
 Industrial piping where mechanical protection and condensation control are needed
 Applications requiring quick installation of pre-formed bend insulation
Key specifications
 Material: closed-cell polyurethane (PU) foam core with PVC outer jacket
 Shape: pre-formed elbow designed for pipe bends
 Size: 20 x 28 (nominal dimensions for use with corresponding insulated pipe runs)
 Thermal performance: low thermal conductivity of PU foam suitable for thermal loss reduction
 Moisture resistance: closed-cell structure reduces water absorption
 Mechanical protection: PVC jacket provides abrasion resistance and ease of cleaning
How to use
Fit the insulation elbow over the pipe bend so that the pre-formed curvature matches the pipe geometry and maintains continuous contact with the adjacent straight-run insulation. Secure seams and joints according to standard installation practice for thermal insulation, using compatible adhesives, tape or mechanical fasteners as required to achieve a tight seal. Ensure surfaces are clean and dry before installation to promote good adhesion and to minimize the risk of trapped moisture.
Usage recommendations
For best performance, verify compatibility of the elbow dimensions with the existing insulated pipe diameter and adjacent insulation thickness. Follow local building codes and system design requirements for thermal insulation and vapor barriers. Avoid prolonged exposure of the PVC jacket to direct sunlight or aggressive chemicals; where necessary, provide additional UV protection or chemical shielding.
