High-Temperature Electrical-Insulating Tube Sleeving
This sleeving withstands temperatures up to 390° F and is often used to insulate connections in transformers, relays, and solenoids. It prevents electricity and heat from dissipating from wire and cable. When exposed to flame, it will self-extinguish and produce a nonconductive ash. It’s flame rated VW-1 to meet requirements for preventing the spread of flames based on a timed test with vertically suspended material. Made of silicone-coated fiberglass, it resists chemicals.
Electrical-Insulating Tube Sleeving
Add a layer of insulation to prevent electricity and heat from dissipating from wire and cable. This sleeving is often used in motors, transformers, and generators. Made of coated fiberglass, it resists abrasion, acids, alkalies, and chemicals.
Vinyl-coated sleeving resists wax and alcohol. Sleeving is flame-rated VW-1 to meet requirements for preventing the spread of flames based on a timed test with vertically suspended material.
Expandable Electrical-Insulating Tube Sleeving
A specially formulated silicone rubber coating allows this fiberglass sleeving to stretch over items during installation; it then tightens around its contents for a secure fit. Often used in motors, generators, and transformers, it prevents electricity and heat from dissipating from wire and cable. It has good chemical resistance.
Snap-In Pipe and Tubing Grommets
These grommets have two flanges that snap around holes and flex to compensate for misalignment and movement of pipe and tubing. They're often used for routing applications in panel walls. Made of plastic, these grommets are chemical resistant and won't dry out and become brittle when exposed to UV rays. All have a medium-hard rating to withstand high levels of impact. They can be used outdoors.
