Introduction
AP Armaflex Self-Seal Pipe Insulation is designed for insulating plumbing, HVAC, and refrigeration lines. This foam tubing provides a solution for condensation control, energy efficiency, and pipe protection. Its closed-cell structure acts as a barrier against moisture, preventing condensation and reducing heat transfer.
This insulation helps prevent water damage and corrosion by stopping pipe sweating. It also contributes to energy savings by maintaining desired water temperatures, thereby reducing the energy consumption of HVAC systems and water heaters.
The product is fiber-free and non-particulating, holding GREENGUARD Gold Certification for indoor air quality. It is designed for durability, resisting tears, crushing, and degradation, and protects pipes from freezing temperatures and impacts.
Installation Instructions
Follow these steps for proper installation of AP Armaflex Self-Seal Pipe Insulation:
- Measure the Pipe: Carefully measure the outer diameter (OD) of your pipe.
- Select Correct Size: Refer to the pipe size guide below to select the corresponding insulation size. Ensure the insulation's inner diameter (ID) matches your pipe's outer diameter for a snug fit.
- Cut to Length: Measure the length of the pipe section to be insulated and cut the Armaflex tube to the required length using a sharp utility knife.
- Prepare for Application: The insulation features a factory-applied, pressure-sensitive adhesive Lap Seal. Gently separate the two halves of the insulation along the pre-cut seam.
- Position on Pipe: Slip the insulation over the pipe. Ensure the seam is aligned properly.
- Seal the Seam: Peel the release liner from the adhesive strip. Press the seam firmly together along the entire length to create a secure seal. Ensure there are no gaps.
- Insulate Fittings and Valves: For elbows, tees, and valves, use Armaflex sheets or pre-formed fittings (sold separately) to ensure complete insulation coverage.

Product Functionality and Benefits
Once installed, AP Armaflex insulation provides continuous thermal and moisture control for your piping systems.
- Condensation Control: The closed-cell foam structure effectively prevents surface condensation on cold water pipes, refrigeration lines, and HVAC systems. This mitigates moisture damage, rust, and mold growth.
- Energy Efficiency: By reducing heat loss on hot water pipes and preventing heat gain on cold lines, the insulation helps maintain desired fluid temperatures. This reduces the energy demand on water heaters and HVAC equipment, leading to lower energy consumption.
- Pipe Protection: The durable, flexible foam provides a protective layer against physical damage from impacts and abrasion. It also offers protection against freezing in cold conditions, safeguarding pipes from bursting.
Care and Maintenance
AP Armaflex pipe insulation is designed for years of maintenance-free performance. Regular inspection is recommended to ensure the integrity of the insulation, especially in areas prone to physical damage or extreme conditions.
- Inspection: Periodically check for any signs of damage, such as tears, punctures, or gaps in the sealed seams.
- Cleaning: If cleaning is necessary, wipe the surface with a damp cloth. Avoid harsh chemicals or abrasive cleaners.
- Outdoor Applications: For pipes exposed to direct, intense sunlight, a protective coating like Armacell's Armafinish is recommended to maximize the insulation's lifespan and UV resistance.
Troubleshooting
If you observe issues with your insulated pipes, consider the following:
- Condensation on Insulated Pipes:
- Check for Gaps: Ensure all seams are fully sealed and there are no gaps where moisture can penetrate or air can circulate.
- Verify Fit: Confirm that the insulation size matches the pipe's outer diameter. Loose-fitting insulation can reduce effectiveness.
- Insulate Fittings: Ensure all fittings, valves, and joints are also properly insulated. Uninsulated components can be points of condensation.
- Insulation Damage:
- Physical Damage: Inspect for tears or punctures. Small damages can be repaired with Armaflex adhesive or tape. Larger damaged sections may require replacement.
- UV Degradation (Outdoor): If insulation exposed to direct sunlight shows signs of degradation, consider applying a UV protective coating.
