Rubber Foam Pipe
Rubber foam pipe insulation wraps chilled water, HVAC, and refrigeration pipes with flexible, closed-cell elastomeric tubes that prevent condensation without a separate vapor barrier. Temperature range typically from -40 °C to +105 °C, tube ID from 6 mm to 160 mm, wall thicknesses from 6 mm to 32 mm, thermal conductivity around 0.034 to 0.040 W/m·K — confirm exact dimensions by inquiry. Supplied from our own and partner factories — combined capacity up to 450,000 t/yr, with a one-container MOQ and LCL support.
- Closed-cell structure provides integrated vapor barrier — eliminates the separate vapor barrier that fails at joints on mineral wool pipe insulation, leading to condensation drip and mold growth.
- Flexible tube slides or wraps onto pipe in one step — no field cutting, no facing application, no taping of separate vapor barrier layers.
- Available plain, pre-slit, and with adhesive closure for new installation, retrofit, and maintenance scenarios.

Problems This Product Solves
Common pain points this product is built to address.
Condensation on cold pipes causes dripping, mold growth, and corrosion.
Chilled water and refrigerant pipes collect moisture from surrounding humid air. Without closed-cell insulation with integrated vapor resistance, condensation forms on the pipe surface — dripping onto ceilings, promoting mold growth in concealed spaces, and accelerating pipe corrosion.
Mineral wool pipe insulation loses performance when its vapor barrier fails.
Fiber insulation on cold pipes depends on a separate vapor barrier to prevent moisture migration into the insulation layer. Vapor barrier failure at joints, penetrations, and damage points allows moisture to accumulate inside the insulation — permanently degrading thermal performance and causing corrosion under insulation (CUI).
Wrapping sheet material around pipes wastes time and produces inconsistent coverage.
Cutting flat sheet stock to fit each pipe diameter requires measuring, cutting, wrapping, and sealing every piece on site. Pre-formed tube insulation eliminates this labor — each tube is sized to the pipe diameter and installs in a fraction of the time.
Multi-size pipe programs need consistent tube supply across all diameters.
A mechanical room may have chilled water, hot water, and refrigerant pipes in different diameters. Sourcing tube insulation across all sizes from one supplier simplifies ordering, reduces delivery coordination, and ensures consistent material properties across the pipe program.
Engineered for Consistent Performance
Every batch is produced under controlled conditions and verified against international standards, so what you specify is what you receive — project after project.
Product Benefits
What sets this product apart in real projects.
Pre-formed tube shape
Slides over or snaps onto pipes without sheet wrapping, reducing installation steps on straight runs.
Closed-cell vapor resistance
Integrates thermal insulation and vapor resistance in one layer, eliminating the need for a separate vapor barrier membrane on cold lines.
Pre-slit option for retrofit
Snap-on installation over existing piping without disconnecting the line, saving time on renovation and maintenance projects.
Self-adhesive slit closure
Peel-and-press seam seal speeds installation and reduces reliance on separate adhesive application for vapor-tight closure.
Range of pipe OD sizes
Available in multiple inner diameters to match common pipe sizes, reducing the need for field cutting or shimming to achieve a proper fit.
Best-Fit Applications
Rubber Foam Pipe is most useful when the pipe system needs flexible tube insulation with integrated condensation control.
Chilled water piping
Closed-cell tube insulation controls condensation on low-temperature water supply and return lines.
HVAC refrigerant lines
Flexible tube format fits copper refrigerant piping in commercial and residential air conditioning systems.
Domestic water pipes
Prevents sweating on cold water supply lines and provides freeze-delay protection in exposed or semi-conditioned spaces.
Condensation-prone mechanical rooms
Covers exposed pipe runs in plant rooms, basements, and equipment areas where humidity and cold pipe surfaces create drip risk.
Split-system AC lines
Sized to fit common split-system refrigerant and drain line diameters for residential and light commercial installations.

When It's Not the Best Fit
Rubber Foam Pipe is not the best first choice for every pipe insulation condition. Review alternatives when:
Selection Guide
Answer these to narrow down the right specification.
What is the pipe OD and pipe material?
Determines the correct tube inner diameter for a snug fit without compression or gaps.
What wall thickness is needed for the temperature differential?
Matches insulation thickness to the operating temperature difference between pipe surface and ambient conditions.
Is the pipe already installed or under construction?
Determines whether plain tube (slide-on for new install) or pre-slit tube (snap-on for retrofit) is needed.
Is facing, adhesive closure, or jacketing required?
Selects the correct variant: foil faced for outdoor UV, self-adhesive for speed, plain for standard indoor runs.

Frequently Asked Questions
Answers to common questions about this product.
Choose rubber foam pipe for chilled water, HVAC refrigerant, and domestic water piping where condensation control is the primary concern and service temperatures are within the product's range.
Measure the actual outer diameter of the pipe to be insulated, not the nominal pipe size. Rubber foam tubes are sized by pipe OD for a snug fit.
Wall thickness depends on the temperature differential, ambient humidity, and condensation prevention target. Share operating conditions for thickness recommendation.
Plain tube slides over the pipe end during new installation. Pre-slit tube opens to wrap around existing installed pipes for retrofit work.
Yes — mixed-size orders are common for mechanical projects. Provide the complete pipe schedule with quantity by size for consolidated quotation.
