Thermal Insulation Pins

China Made Self Adhesive Stick Pins for Insulation, Peel & Stick Pins for Duct Liner

Product Overview:

Looking for a fast, tool-free, and reliable way to install insulation without welding or drilling? Our China Made Self Adhesive Stick Pins for Insulation, also known as Peel & Stick Pins for Duct Liner, are the perfect solution. Designed for maximum convenience and strong holding power, these pins feature a robust steel pin attached to a high-performance industrial adhesive base. Simply peel off the release paper and stick them directly onto sheet metal, plastic, or other smooth surfaces. Ideal for HVAC contractors, fabricators, and builders, our pins offer a cost-effective, factory-direct fastening system that saves labor time while ensuring a secure, long-lasting insulation hold.

Key Features & Benefits:

• True "Peel & Stick" Convenience: Say goodbye to welding guns, drills, and screws. Installation takes only seconds—just clean the surface, peel the liner, and press firmly. This drastically reduces installation time and labor costs, especially on large-scale ductwork projects.

• High-Performance Industrial Adhesive: Equipped with a thick, pressure-sensitive foam or rubber adhesive pad, these pins form an incredibly strong initial tack and cure to a permanent bond. The adhesive is engineered to resist aging, humidity, and temperature fluctuations, ensuring the pin stays put in demanding HVAC environments.

• Premium Pin Material: The pins are made from high-quality galvanized steel or stainless steel, providing excellent resistance to bending and corrosion. They are fully compatible with standard self-locking washers or dome caps to lock insulation in place.

• Clean & Safe "Cold Work" Installation: Since no welding or drilling is required, there are no sparks, no metal shavings, and no risk of damaging delicate ductwork or surrounding equipment. This makes them perfect for retrofitting, occupied buildings, or marine environments where safety regulations prohibit open flames or sparks.

• Versatile Insulation Compatibility: Works flawlessly with fiberglass duct liner, foam insulation boards, mineral wool, and acoustic panels. The sharp pin point easily penetrates various densities of insulation material for a quick, secure fit.

  
  

Typical Applications:

• HVAC Duct Liner Installation: The primary use for securing fiberglass or elastomeric foam liners to sheet metal ducts in commercial and residential air conditioning systems.

• Duct Wrap & External Insulation: Fastening insulation blankets to the exterior of rectangular or round ductwork.

• Equipment & Machinery: Installing soundproofing or thermal insulation on compressors, air handlers, and factory equipment.

• Marine & Offshore: Ideal for shipbuilding and offshore platforms where "cold work" (no welding) is strictly required for safety compliance.

• General Building Insulation: Quick-fix solutions for walls, ceilings, and HVAC enclosures requiring a clean, efficient fastening method.
