About Selecting Thermal Insulation

High-Temperature Moisture-Seal Heat-Shrink Tubing

This PTFE tubing withstands temperatures up to 450° F and has an inner lining that creates a water-resistant seal when heated.

Chemical-Resistant Moisture-Seal
Heat-Shrink Tubing

Made of PVC, this tubing resists chemicals, oil, and solvents. The adhesive lining creates a water-resistant seal when heated.

Moisture-Seal Heat-Shrink Tubing

Create a water-resistant seal—this tubing has an adhesive lining that melts when the tubing is heated and bonds to the underlying surface.

Extra-Thick Moisture-Seal Heat-Shrink Tubing

Extra-thick walls provide better protection against abrasion and tears than standard moisture-seal tubing, as well as creating a water-resistant seal.

High-Shrink-Ratio Moisture-Seal Heat-Shrink Tubing

Create a tight, water-resistant seal over irregularly shaped components. When heated, this tubing shrinks down to about 1/6th of its original ID, while an adhesive lining melts and forms a barrier around your component.

Clean Room Heat-Shrink Tubing

After being cleaned with alcohol, this tubing is bagged and sealed in a clean room. It's certified for material quality and purity.

No-Heat Shrink Tubing

Create a permanent seal without applying heat. This tubing is also known as cold-shrink tubing.

Harsh Environment Heat-Shrink Tubing Assortments

Maintain a supply of tubing in a variety of sizes that withstand abrasion, moisture, and chemicals.

Heat-Shrink Cable Splitters

Also known as breakout boots, these splitters insulate and seal the point where wire splits off from cable, or where cables exit from conduit.

Heat-Shrink End Caps

Seal the end of crimped connections, such as motor coils, to insulate and protect them from moisture and abrasion.

Moisture-Seal Wrap for Heat-Shrink Tubing

Use this wrap with heat-shrink tubing to create a moisture-resistant seal. Apply it like tape around wire and cable, then slide the tubing over the wrap. The wrap melts when tubing is heated and bonds to the underlying surface.

Tapered Heat-Shrink Tubing

A different shrink ratio on each end allows this tubing to fit over cable assemblies and wire harnesses with large connections, or around connectors with a 90° elbow.

Wrap-Around Heat-Shrink Tubing

Protect wire and cable without disconnecting them from an assembly. For a water-resistant seal, this tubing has an adhesive lining that melts when heated to bond it to the underlying surface.

No-Heat Shrink End Caps

With a spiral-wound core, these end caps form a permanent seal on the end of your crimped wire or cable without heat or tools.

Thermal Insulation

Chemical-Resistant Cellular Glass Pipe Insulation

Very rigid with a 0% water absorption rate, this insulation is unaffected by corrosive environments, organic solvents, and most acids. It is typically used in chemical-processing systems and underground lines.

Tear-Resistant Silicone Foam Pipe Insulation

Even at high temperatures, these tubes remain flexible to stretch over components without tearing. They restrict absorption of water, air, and gas and are typically used on hot and cold water lines and electrical components.

Economical Flexible Polyethylene
Foam Pipe Insulation

Less flexible than rubber foam, this insulation restricts absorption of water, air, and gas. It is typically used in plumbing applications

UV-Resistant Flexible Rubber
Foam Pipe Insulation with Jacketing

Ready to withstand weather and UV rays, this insulation comes wrapped in protective jacketing.

Flexible Rubber Foam Pipe Insulation

Soft and easy to install, this insulation restricts absorption of water, air, and gas. It is often used on cold and hot water lines and refrigeration lines.

Ultra-Insulating Low-Temperature
Polyisocyanurate Foam Pipe Insulation

This very rigid insulation offers the lowest heat-flow rate of our pipe insulation and restricts absorption of water, air, and gas. It is typically used in process piping and chiller plants and performs best in applications below 50° F.

Pipe Condensation-Reducing Rubber Strips

Wrap pipes, tubing, and fittings to prevent condensation from forming. These strips are for use on copper, iron, and steel.

Rigid Silica Ultra-Insulation Sheets for Furnaces

Typically used in ovens and furnaces, these are the most efficient of our rigid high-temperature insulation sheets. Please note that they require special care when installing since the crumbly material is difficult to work with and will crack easily. Sheets lose strength over time and are intended to be installed behind another facing or insulation material.

Humidity-Resistant Paper Insulation Sheets

Often used in high-humidity applications for its low moisture absorption, this flexible paper insulation is made of inorganic materials. It’s typically used in appliances and electrical devices.

Impact-Resistant Low-Temperature
Rigid PVC Foam Insulation Sheets

Made of rugged PVC foam, these rigid sheets absorb impact and restrict the absorption of water, air, and gas. Use in applications with operating temperatures below 32° F.

Low-Temperature Rigid Cork Insulation Sheets

Use these sheets in operating temperatures below 32° F, such as cold-storage applications.

Moisture-Resistant Low-Temperature
Rigid Polystyrene Foam Insulation Sheets

These sheets resist the absorption of water, air, and gas and are widely used in cold-storage and packaging applications.
