About Sleeving

High-Temperature Wire

Even at 480° F—hotter than some industrial ovens—this wire’s insulation won’t melt.

High-Temperature Cable

For high-heat applications such as furnaces and ovens, this cable's insulation withstands temperatures of 390° F and higher.

Temperature and Humidity Monitoring

Thermocouple Wire

Make your own thermocouples.

RTD Wire

Make custom RTD probes.

Sleeving

High-Temperature Expandable Sleeving

Protect cable, hose, and pipe in high temperature environments—this sleeving withstands temperatures over 450° F. It stretches to fit over items for easy installation, then tightens around its contents for a secure fit.

High-Temperature
Electrical-Insulating Tube Sleeving

This sleeving is often used to insulate connections in transformers and relays. It prevents electricity and heat from dissipating from wire and cable.

Expandable Electrical-Insulating Tube Sleeving

A specially formulated silicone rubber coating allows this sleeving to stretch over items during installation; it then tightens around its contents for a secure fit.

Electrical-Insulating Tube Sleeving

Add a layer of insulation to prevent electricity and heat from dissipating from wire and cable.

Spark-Resistant Tube Sleeving

A silicone rubber coating on this fiberglass sleeving protects against sparks and molten metal splash.

Extra-Thick Spark-Resistant Tube Sleeving

Made from thicker and denser fiberglass than standard spark-resistant sleeving, this sleeving is more abrasion resistant and provides better insulation. The silicone rubber coating protects against sparks and molten metal splash.

Fiberglass High-Temperature Sleeving

This sleeving withstands temperatures over 1000°F, such as in refineries.

Aramid High-Temperature Sleeving

A blend of Aramid and fiberglass gives this sleeving excellent abrasion resistance. It can withstand temperatures up to 650° F

Refrigerant-Resistant Sleeving

Coated in acrylic, this sleeving holds up to rapid temperature changes, and it won’t break down from refrigerants, solvents, oil, or lubricants. Also known as hermetic sleeving, it’s designed to protect wires and hose inside air-tight motors, such as those used in air conditioners.

Spark-Resistant Hook-and-Loop
Wrap-Around Sleeving

Silicone rubber coats this fiberglass sleeving to shed sparks and molten metal splash. It has a slit along the entire length so it easily wraps around wire, cable, and hose without disconnecting them.
