Insulation sleeving is a type of protective, heat-resistant tubing designed to shield cables, hoses, and wires from extreme temperatures and environmental wear. Since these products must act as a thermal barrier under demanding conditions, they are made from durable materials like fiberglass, with silicone rubber, acrylic, or vinyl-coated interfacing.
Insulation sleeving products from National Plastics and Seals, Inc. are flexible, corrosion-resistant, and available in a variety of sizes and coating options. Our solutions are fully customizable to your needs and built to comply with diverse industry regulations, including specific UL, CSA, and temperature class ratings.
Features and Benefits
While insulation sleeving is designed for thermal protection, it offers many additional features and benefits. National Plastics’ products are trusted by some of the world’s most demanding industries due to their chemical tolerance, sound control, and more.
Electrical Insulation
Electrical insulation sleeving prevents electrical currents from leaking and creating shocks or short circuits. It also prevents wires from reaching other wires or cables that may be located nearby, extending their lifespan and ensuring effective performance.
Mechanical Support
Industrial assemblies involve fragile wires and critical equipment that is highly sensitive to abrasions, moisture, and rust. Installing insulating sleeves provides added mechanical support and protection against harmful environmental conditions.
Corrosion Resistance
Insulating sleeves are made from corrosion-resistant materials that offer a long lifespan, such as fiberglass, rubber, silicon, or plastic. Even with constant exposure to corrosive chemicals, these specially engineered products safely surround sensitive wires and cables, providing greater protection.
Sound Control
Ongoing exposure to loud noises is a common challenge in many workplaces, putting employee health at risk. Many of the environments these products are used in are inherently noisy, such as engine manifolds, exhaust systems, and heavy-duty industrial equipment. Insulating sleeves act as an added soundproofing barrier, helping to minimize equipment noise and promote the well-being of surrounding workers.
Chemical Tolerance
Since they are made from fiberglass, insulating sleeves from National Plastics are highly chemical-resistant. Insulation sleeves are engineered with constant exposure to corrosive chemicals in mind, resulting in dependable performance even under rigorous conditions.
Highly Adjustable and Versatile
Engineered with flexibility in mind, insulation sleeving products easily conform to installation sites and come in a variety of shapes and sizes to promote a perfect fit. Insulation sleeving from National Plastics accommodates many types of pipes and cables and is easy to install and adjust due to its lightweight, flexible nature.

Insulation sleeving is used throughout an extensive range of industries, with applications that range from heavy-duty industrial equipment, plumbing, commercial installations, and much more. Some of the most important roles these products play include:
Electrical insulation
Insulating wires and cables is important for preventing electrical faults and short circuits. Insulation sleeving protects the electrical components within motors, transformers, and other types of equipment. It also provides insulation for electronic devices and components like switches, connectors, and cables.
Thermal Protection
Cables, hoses, and pipes often require protection against high temperatures, especially those installed within demanding environments like engines and exhaust systems. Insulation sleeving reflects heat and helps maintain safe temperatures, which is important to keep pipes from freezing in unheated or outdoor locations.
Mechanical Protection
Insulation sleeving protects cables, hoses, and wires from abrasion, wear, and physical damage. It helps prevent external damage and accidental contact, acting as a barrier against sharp edges and rough surfaces.
