Frequently Asked Questions: Sleeving

Conduit Tubing


What is expandable sleeving?

Expandable sleeving serves as an alternative to heat shrink tubing, and is part of Allied's supply of tubing and cable harnessing solutions. Unlike heat shrink tubing, sleeving does not shrink. Instead, it conveniently fits over wire and cable. Sleeving products typically cost less than heat shrink tubing.

How many types of sleeving are there?

Many types of sleeving products are on the market. Two commonly requested styles are polyester expandable sleeving and fiberglass sleeving. High temperature ceramic braided sleeving and expandable braided sleeving are also popular products.

What are some of the benefits of using expandable sleeving rather than heat shrink tubing?

Expandable sleeving is convenient. It does not require the time, effort, or tools necessary for heat shrinking. It is designed to fit well over wire and cable without any alterations. Cost savings are another major advantage of using sleeving rather than heat shrink tubing.

In what applications would fiberglass sleeving be best to use?

Fiberglass sleeving is intended for high temperature applications. Because the sleeving is intended for challenging environments, it is constructed to withstand extreme heat. Heat-treated fiberglass sleeving is designed for applications up to 1200ºF. Other types of fiberglass sleeving meet other temperature requirements. Vinyl-coated is designed for applications up to 130ºC, acrylic-coated may be used up to 155ºC, and silicone-coated is intended for applications up to 200ºC.

How do you use expandable braided sleeving?

Expandable braided sleeving is easy to use. Like other types of sleeving, simply push the expandable braided sleeving over fittings in order to expand its size. The expandable sleeving then forms a tight fitting cover that adjusts to all shapes and contours.
