1/2" Wall Insulation Tube Pipe, Rubber Pipe,6' x 5/8" Pipe (O.D.)

K-FLEX® INSUL-TUBE® – 5/8" ID x 3/8" Wall x 6' Elastomeric Pipe Insulation

The K-FLEX® INSUL-TUBE® 6RX048058 is a flexible, closed-cell elastomeric foam insulation designed for mechanical piping systems. With a 5/8" nominal inner diameter, 3/8" wall thickness, and 6-foot length, it provides thermal efficiency while helping to prevent condensation and moisture accumulation on chilled water and refrigeration lines. Suitable for commercial and industrial HVAC, plumbing, and refrigeration systems.

Key Performance Attributes

• Thermal Efficiency – Reduces heat transfer to maintain system temperature and minimize energy loss.
• Wide Temperature Range – Rated for continuous operation from -297°F to +220°F (-182°C to +104°C).
• Moisture Vapor Resistance – Closed-cell structure limits moisture penetration, reducing risk of mold and corrosion under insulation.
• Compatible with Heat Tracing – Approved for use with properly installed heat tracing systems.
• Flexible Format – Allows for quick fitting over piping without specialized tools.
