Lhazemu Pipe Insulation Tubing
Size and material: Inner diameter 1-1/2″ (38 mm), total length 6 ft, includes a fire-resistant insulating foam. Temperature tolerance ranges from -20°F to 176°F. The material is non-irritating and non-toxic. This insulation is suitable for industrial and air conditioning equipment, guitar stands, shelves, and as a buffering layer to protect wooden surfaces or sports gear.
Best for: General purpose insulation on 1-1/2″ pipes and equipment protection in workshops or utility rooms. The self-extinguishing, fire-retardant properties add a safety buffer for various installations.
Limitations: Data notes basic insulation specs but does not specify a pre-slit design; ensure a proper fit around existing pipes when installing. Also check local code compliance for fire-retardant materials in specific applications.
Amylove Brown Foam Pipe Insulation Foam Tube (12 Pack)
Size and material: Each piece is about 1 m (3.28 ft) long, outer diameter ~58 mm (2.28″), inner diameter ~38 mm (1.5″), thickness ~10 mm. Made from quality PEP foam; flexible, durable, and reusable. Fireproof and heat-insulating with sound-absorbing properties.
Best for: Bulk replacements for 1.5″ copper pipes and outdoor pipe insulation for pools, lakes, or crafts. The bundle offers plenty of quantity for repetitive projects.
Limitations: Outer diameter is slightly larger than some pipes; verify pipe OD before purchase to ensure a snug fit around curved sections.
Kathfly 12 Pack Foam Tube Insulation 1.5 Inch
Size and material: Each tube is 1.5 inches in diameter and 15.7 inches long with a self-adhesive design. The included foam is flame retardant and easy to seal once the protective backing is removed.
Best for: Replacement insulation for many 1.5″ pipes and quick DIY repairs where a pre-slit, self-adhesive edge speeds installation. Suitable for hot and cold water pipes.
Limitations: Shorter length per piece may require multiple pieces for longer runs; plan for joins when insulating long sections.
Amylove Black Foam Tube Insulation (12 Pack)
Size and material: Each piece measures about 1 m in length, outer diameter ~58 mm, inner diameter 38 mm, thickness ~10 mm. Made from soft, resilient PEP foam; fireproof and heat-insulating with sound-absorbing properties.
Best for: Outdoor insulation for water pipes, pools, or recreational equipment; color black helps blend with many installations and reduces visible wear.
Limitations: Like other bulk foams, you may need to cut or adjust for irregular pipe shapes; ensure accurate interior diameter for a tight seal.
hmevsafinect Pipe Insulation Foam Tube
Size and material: Foam tubing with ID 1-1/2″ (38 mm), OD 2-1/4″ (56 mm), thickness 3/8″ (9 mm). Temperature tolerance from -40°C to 80°C. Fire retardant, self-extinguishing, and non-toxic. Provides flexibility, bending resistance, waterproofing, and sound absorption.
Best for: Heavy-duty insulation on HVAC and piping runs where a broad temperature range and robust flame retardant properties are important. Suitable for guitar stands, exercise equipment handles, and roof racks as mentioned in its product context.
Limitations: Slightly thicker outer diameter may affect fitment on tightly spaced pipes or accessories with tight clearance.
Buying Guide
What makes 1.5 inch pipe insulation the right size?
1.5 inch refers to the inner diameter that fits snugly around 1-1/2 inch pipes. Choosing the correct ID ensures minimal air gaps and improved thermal performance. Check both pipe OD and ID of the insulation to ensure a clean seal and effective insulation.
What material properties matter?
Look for fire-retardant, self-extinguishing foam for safety. Non-toxic, non-irritating raw materials reduce indoor air concerns. Flexible and easily cut or pre-slit designs save time on installation. Consider thermal conductivity, weather resistance, and moisture protection for outdoor use.
Pre-slit vs. non-slit designs
Pre-slit, self-adhesive edges simplify installation, especially on curved pipes. Non-slit designs may require cutting and sealing, which can be more labor-intensive but offers a tighter fit for some configurations.
Best practices for installation
Clean the pipe surface before applying insulation. For self-adhesive tubes, remove backing and press firmly along the pipe. For non-adhesive tubes, use tape or clamps to secure ends. Allow for joints when insulating long runs to maintain continuous protection.
Durability and reuse considerations
Foam insulation can be reusable in some cases, but repeated bending and tearing can reduce effectiveness. Choose thicker walls or higher-quality foam for areas subjected to frequent movement or impact (guitar stands, gym equipment, or outdoor equipment).
Environmental and safety considerations
Prefer materials labeled fire-retardant and low-toxicity. Ensure compatibility with the intended environment (indoor vs. outdoor, high humidity, or chemical exposure). For outdoor or pool use, verify UV resistance and moisture protection to prevent degradation over time.
