Why we love it
  • Optimized size for various pipes.
  • Superior thermal insulation performance.
  • Durable and flexible rubber material.
Main Highlights
  • Optimized Dimensions: featuring a comfortable size with a length of about 5.91 ft/ 1.8 m, the pipe lagging foam meets your insulation needs; The tube possesses an inner diameter of about 0.87 inch/ 22 mm, and a thickness of about 0.35 inches/ 9 mm, making it suitable for various pipe sizes
  • Quality Insulation Performance: with outstanding thermal insulation performance, our pipe insulation foam tube ensures an effective antifreeze protection for various pipelines; Despite the average temperature being 0 degrees Celsius, this tube ensures a low thermal conductivity of 0.034W/mk, ensuring excellent heat insulation performance
  • Strong and Sturdy Material: our pipe cover is made from quality rubber; It has reliable properties such as softness, resistance to bending, cold resistance, heat resistance, flame retardant, waterproof, low thermal conductivity, shock absorption, and sound absorption
  • Quick and Easy Installation: to preserve pipe insulation during shipping, we do not precut it; For optimal insulation performance, install the pipe insulation directly onto the pipe before pipe installation; If the pipe is already in place, simply cut the foam and stick with glue, glue is more durable than double-sided tape; Please note: the pipe insulation withstands -20 to 120 Celsius, when adhered with double-sided tape, the temperature range is reduced to 0 to 40 Celsius
  • Flexibility and Elasticity: experience the pleasure of easy handling with our foam tubing that boasts winding capabilities, and softness that provides bend resistance and shock absorption; They're also resistant to extreme temperatures, making them the reliable choice for your insulation needs

16.4 Ft x 3.2 Inch Pipe Wrap Insulation Tape - Pipe Insulation Lagging Wrap - Foam Adhesive Wrap Cover for Outdoor Indoor Cold Hot Water Pipes,Winter Freeze Protection,Reduce Heat Loss

16.4 Ft x 3.2 Inch Pipe Wrap Insulation Tape - Pipe Insulation Lagging Wrap - Foam Adhesive Wrap Cover for Outdoor Indoor Cold Hot Water Pipes,Winter Freeze Protection,Reduce Heat Loss

GIONAR
Why we love it
  • Installs easily with adhesive.
  • Durable for extreme weather.
  • Reduces energy consumption efficiently.
Main Highlights
  • 【High quality material】The water pipe insulation is made of NBR material ,whose honeycomb closed cell has high-density characteristics, enhancing the toughness and wear resistance of water pipe insulation pipes,making it quickly rebound when external objects collide with the protective strip and has good insulation effect .
  • 【Self adhesive backing】The water pipe insulation sleeve adopts 3M aviation double-sided adhesive backing, which widens the adhesive surface, enhances adhesion, and tightly fits without easy detachment.
  • 【Strong temperature resistance】The tube insulation wrap can effectively avoid the influence of temperature and prevent water pipes from freezing due to low temperature in cold weather, which can lead to problems such as water pipe rupture and leakage.
  • 【Energy saving and consumption reduction】Our water pipe insulation can minimize the heat release of the water pipe, reduce the energy required for transporting hot water, and reduce energy consumption. While maintaining insulation, it can also reduce the flow resistance of water, reduce the power consumption of the water pump, and thus achieve the goal of energy conservation.
  • 【Improving comfort】The water pipe insulation tape can keep the surface temperature of the water pipe relatively high in the cold winter and maintains the transmission of hot water and avoids the situation of low water temperature inside the pipe,making the warm water can be directly discharged without waiting for the cold water to flow clean when the faucet is turned on.
