Product Description

Insultherm Braided Sleeving Logo

Techflex® Insultherm®

Insultherm® is an extremely high temperature resistant sleeve commonly used as thermal protection for wires, cables and hoses that are subjected to continuous and extreme high temperature environments, such as engine manifolds and exhaust systems. Insultherm is braided from fiberglass yarns and saturated with high temperature resins that improve the product's stability and minimize irritating fiberglass dusting during cutting and installation. The sleeving is tough and durable, maintaining its tight structure under extreme vibration, abrasion, mechanical stress and temperature variations. Insultherm® is available in a wide range of diameters. It cuts cleanly with scissors and installs easily over a variety of applications to either deflect or retain heat in environments up to 1,200°F.

OPERATING TEMPS: -94° to 1,202°F (-70° to 650°C.)

MELT TEMP: 2048 ºF / 1120 ºC

COLOR OPTIONS: Black, Silver, & Red



Why Do I Need High Temperature Sleeving?

There are many applications where high temperature braided sleeving is essential, such as in aerospace, automotive, industrial, and military settings. In these environments, wires and cables may be subjected to intense heat from engines, exhaust systems, or other high-temperature sources. Without proper insulation and protection, these components can become damaged or even fail, leading to system downtime, safety hazards, and costly repairs.

Tips for Installing & Terminating Braided Sleeving

How To Determine What Diameter Sleeving You Need

Bundle the cords that you’ll be covering and measure the diameter of the bundle. If you want a snug fit, choose a braided sleeving option with a slightly smaller diameter than that of your cables. If you want a loose and flexible fit, choose a braided sleeving option with a diameter that is equal to or slightly larger than that of your cables. Keep in mind that braided sleeving loses 2% to 3% of its length when it expands. Be sure to plan accordingly!

How To Terminate Sleeving with Heatshrink Tubing

Heatshrink Tubing is the ideal way to create a tight, professional finish on any wire, hose or cable management project. Once shrunk, the tubing will hold its reduced state, even at elevated temperatures. This application can be used to protect, color code, brand, or secure ends or sections of braided sleeving. A Heat Gun is required to properly apply heatshrink tubing. You can find a guide to the proper technique for working with heatshrink tubing Here.

About The Insultherm® Family of Products

Insultherm® products are extremely high temperature resistant material commonly used as thermal protection for wires, cables and hoses that are subjected to continuous and extreme high temperature environments, such as engine manifolds and exhaust systems.

Insultherm®:This traditional sleeving is tough and durable, maintaining its tight structure under extreme vibration, abrasion, mechanical stress, and temperature variations.

Insultherm® Heavy Duty: This is a braided fiberglass sleeving made in a heavy wall construction with a high temp cord braided into the sleeving. Insultherm® HD is saturated with high temperature acrylic resins which adds rigidity and reduces fray when cut.

Insultherm® Tru-Fit: Tru-Fit is often used as primary insulation on low voltage applications such as leads in toasters, coffee makers, ranges, and other appliances. This product is available in a wider range of colors than standard Insultherm®.

Insultherm® Ultra Flex®: Ultra Flex® expands slightly, allowing it to slide easily over wires and follow curves and contours without binding. It is compatible with most bonding & saturation systems.

Insultherm® Ultra Flex® Pro: Ultra Flex® Pro cuts easily with scissors, and special heat treated construction minimizes fraying and dusting during assembly. The Increased wall thickness adds value to insulation.

Insultherm® Spark Plug Boots: These innovative sleeves offers high temperature protection in an easy slip on sleeve that will extend the life of expensive spark plug wires by protecting them where they need it most... at the boot. Just slip these 3/4” diameter double thickness (triple thick at the sewn end) sleeves over any spark plug cable and boot (even right angle boots) to protect them from engine temperatures up to 1,200°F.

Insultherm® Header Wrap: Insultherm® Header Wrap is an extremely high temperature resistant wrap commonly used to contain and manage hot gases in automotive and high performance headers and exhausts.

Insultherm® Header Wrap SI: This exhaust wrap is made from texturized amorphous silica filament yarn woven into a strong and flexible form. Because the yarn is texturized into a bulky form it provides excellent insulating values. Header Wrap SI is not made from leached fiberglass, resulting in a much more wear resistant finished product
