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.
A specially formulated silicone rubber coating on this fiberglass sleeving sheds sparks, molten metal splash, hydraulic fuel, and lubricating oil. Exposure to a torch will char the coating, but will not scorch the fiberglass inner layer. It also resists fraying. Because this sleeving is non-expandable, it does not stretch, so it’s best for applications where you know the exact diameter of the items you need to protect.
A strip of hook-and-loop creates a strong seal along the entire length of this sleeving, yet it can be opened at any point to access contents. Wrap it around wire, cable, and hose without disconnecting them.
Nylon sleeving is made of tightly braided fibers for excellent abrasion resistance. It has the toughness of metal, yet remains flexible.
A specially formulated silicone rubber coats this fiberglass sleeving to shed sparks, molten metal splash, hydraulic fuel, and lubricating oil. Wrap it around wire, cable, and hose without disconnecting them. It has a slit along the entire length and a strip of hook-and-loop that keeps it securely closed but allows you to maintain access along the length of the sleeving.
This common insulation material is typically used on hot and cold water lines and in process piping. To use outdoors, add metal jacketing.
Tubes, elbows, and tees are formed to provide the best fit on pipe and are the easiest to install. If your pipe is larger than the sizes we offer, choose a sheet/strip.
Tubes have an all-service jacket (ASJ) made of kraft paper with an adhesive strip closure. Seal with reinforced insulation tape (sold separately).
Rigid and flame resistant, these insulation tubes meet ASTM E84 5/0 for flame and smoke. They are typically used in process piping and mechanical systems and perform best at temperatures up to 600° F. To use outdoors, add metal jacketing.
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. To use outdoors, add metal jacketing.
Tubes have a kraft paper all-service jacket (ASJ) that resists mold and mildew by allowing moisture to evaporate. They have an adhesive strip closure.
