Custom Heat Shrink Tubing Services

Heat shrink tubing is a thermoplastic tube that shrinks when exposed to heat and is a staple in electrical setups across industries. It is primarily used to protect and insulate electrical wiring, connectors, and other components, and it also helps with the organization and identification of wires within applications.

Peerless Electronics stocks heat-shrink tubing from leading manufacturers for industrial, military, and aerospace applications. In addition to high-quality tubing, Peerless offers cutting and marking as a value-added service. This invaluable offering includes customized sizing for time and cost savings, compliance with standards, and traceability while supporting tubing identification, labeling, and cable organization.

Heat shrink tubing is an insulating material that protects sensitive electronic wiring and components from external factors, such as abrasion, moisture, dust, and sharp objects, that could cause damage. 

The tubing is designed to contract when exposed to heat, creating a tight seal around wires, cables, or components. This process provides insulation, mechanical protection, and strain relief. When the tubing is marked or color-coded, it also supports reliable identification,  traceability, and compliance.

The composition of heat shrink tubing in electrical applications varies depending on the application and includes polyolefin, PVC (Polyvinyl Chloride), fluoropolymers (PTFE, FEP, PVDF, ETFE), elastomers, and other specialty materials. 

This is the most commonly used tubing insulation in electrical applications. Composed of cross-linked polyolefin, this heat shrink tubing is flexible, flame-retardant, and chemically resistant. It’s used for general-purpose insulation in wires and cables for consumer electronics, automotive, aerospace, and industrial applications.

This type of tubing features a dual-wall polyolefin construction with an inner adhesive lining, making it ideal for environmental sealing and offering protection against moisture and corrosion. Adhesive-lined heat shrink tubing is commonly used in automotive harnesses, marine electronics, outdoor electrical connections, and aerospace wiring exposed to humidity.

As the name indicates, high temperature heat shrink tubing can withstand extreme conditions. Comprised of fluoropolymers (PTFE, FEP, PVDF, ETFE) or high-temperature polyolefins, this type of heat shrink tubing can withstand extreme heat (up to 200 - 260°C), offering excellent dielectric strength and chemical resistance. These properties make the tubing ideal for environments with high heat or chemical exposure in aerospace, defense, and industrial electronics.

When cable management is a priority, these ready-made tubing solutions provide faster installation, thanks to pre-sized or spiral designs. These tubing types are typically made of polyolefin (for pre-cut) or flexible PVC/polyolefin (for spiral) and are well-suited for control panels, wiring harnesses, and maintenance kits.

This polyolefin tubing features a built-in solder ring and adhesive lining for a soldered electrical connection and sealed protection in one step. This tubing is commonly used for field repairs, automotive and aerospace wiring, marine connections, and other applications that require quick, reliable joints without the need for external soldering tools.

This protective material is typically supplied in long lengths (spools, reels, or sticks), making cutting heat shrink tubing necessary to meet application requirements. Peerless Electronics offers custom-cut heat shrink tubing as part of its Value-Added Services, saving customers time and reducing waste. Performed by our experienced team at our Hauppauge, NY, headquarters, these services include:

Provides heat shrink tubing cut lengthwise to exact specifications to improve installation speed and minimize material waste.

Provides customized tubing for specific lengths, diameters, or spiral pitches that aren’t part of standard inventory.

Tube marking provides easy identification while also supporting cable organization, compliance with standards, and traceability.Applications & Industries

Heat shrink tubing is a critical component in countless electrical applications across industries, including industrial, aerospace, and military and defense. 

• Industrial Electronics: Heat shrink tubing insulates and organizes control panel wiring in automated machinery, protecting against moisture, abrasion, and debris. 
• Aerospace: Many applications rely on heat shrink tubing for durable, color-coded identification of aircraft wiring to support safety inspections and compliance with MIL-SPEC standards. 
• Military and Defense: In both sectors, heat shrink tubing is used to protect critical systems in aircraft, ground vehicles, and communications equipment from harsh environmental conditions.

Heat shrink tubing must meet specific quality and compliance standards to ensure safety, reliability, and long-term performance. Key certifications include UL (Underwriters Laboratories) for electrical safety, RoHS (Restriction of Hazardous Substances) for environmental compliance, and ISO standards for quality management and manufacturing consistency. Additionally, reputable suppliers maintain material traceability and conduct testing to verify properties such as shrink ratio, dielectric strength, temperature tolerance, and chemical resistance. To verify product qualifications, refer to the tubing's product specifications sheet.

What is Heat Shrink Tubing used for?

It is used to insulate, protect, organize, and identify wires, cables, and components in electrical and electronic systems.

How to choose the right heat shrink tube?

Consideration criteria should include material, diameter, shrink ratio, temperature rating, and application environment (e.g., indoor, outdoor, high-heat, chemical exposure).

Can Heat Shrink Tubing be reused?

No, as soon as it is shrunk, the tubing forms a permanent seal and cannot return to its original size. 

Can you cut heat shrink tubing to length?

Yes, heat shrink tube cutting is offered as part of our Value-Added Services for customers.
