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

K-Flex 6RX048118 – 3/4" x 1/2" Elastomeric Pipe Insulation, 6 Ft Length

The K-Flex 6RX048118 is a flexible, closed-cell elastomeric pipe insulation designed to reduce thermal transfer and control condensation on mechanical piping. This 3/4" nominal size insulation with a 1/2" wall thickness is suitable for use in a variety of HVAC and plumbing systems. Manufactured with NBR/PVC-based foam, it delivers low thermal conductivity and high moisture vapor resistance in demanding conditions.

Performance Features

• Closed-Cell Construction – Prevents moisture ingress and eliminates the need for additional vapor retarders in most conditions.
• Low VOC Emissions – GREENGUARD Gold Certified for compliance with indoor air quality standards.
• EPA-Registered Antimicrobial Protection – Helps resist mold and microbial growth on the insulation surface.
• Fiber-Free, Non-Halogenated Formulation – Contains no formaldehyde, CFCs, HFCs, or PBDEs.
• Flexible and Conformable – Easily wraps around piping configurations, minimizing installation time and material waste.

Technical Specifications

• Nominal Pipe Size: 3/4"
• Wall Thickness: 1/2"
• Length: 6 feet
• Material: NBR/PVC closed-cell elastomeric foam
• Certifications: GREENGUARD Gold, UL 94-rated for flame resistance

Installation Guidance

For optimal performance, pipe surfaces should be clean and dry prior to installation. Insulation can be applied over hot or cold piping and should be secured with appropriate adhesive or tape where necessary. When sealing joints or terminations, use manufacturer-recommended contact adhesives or closure systems to maintain vapor seal continuity.

Recommended Applications

Designed for use on refrigerant lines, chilled water piping, hot water systems, and other HVAC applications. Suitable for residential, commercial, or industrial environments requiring moisture control and thermal efficiency on mechanical piping systems.
