About Sleeving

Slide this sleeving over wire, cable, or hose before adding connectors or making electrical connections. The corrugated construction gives it impact and abrasion resistance similar to conduit, but with more flexibility. It’s ultra-flexible so it’s good for applications that require tight turns. Since it doesn’t have a slit, it keeps out more dust and debris than slit corrugated sleeving.

Steel sleeving is more impact resistant than stainless steel and aluminum sleeving, so it’s better for use in high traffic areas where equipment or people could bump into it.

Heavy Duty Wrap-Around Heaters for Pails and Drums

With One Output Setting

With Three Output Settings

5-15

5-20

6-15

For applications requiring high heat over long periods of time, these aluminized steel heaters warm up faster and are more durable than silicone rubber heaters. They wrap around containers to heat contents without direct contact. Heaters should be positioned at the base of the pail or drum. The spring-loaded clamp closure allows heaters to expand to fit around slightly larger container diameters. Heaters are not for use with flammable materials or in hazardous areas.

Heaters with three output settings have a dial to select low, medium, or high watt density.

Nonadjustable thermostat automatically turns the heater on when the temperature drops below the factory-set temperature and off when it rises above the factory-set temperature. The thermostat keeps the heater temperature at or below 165° F. Adjustable thermostats automatically turn the heater on when the temperature drops below your set temperature and off when it rises above your set temperature. Adjust the set temperature with the dial.

Time-cycle controllers constantly cycle on and off to maintain your set temperature with less fluctuation than thermostats. Turn the dial to adjust the ratio of on to off time. Controllers require a thermometer (sold separately) for calibration and temperature monitoring.

Heaters for Extrusion- and Injection-Molding Barrels

Heat resins, raw materials, and food with these heaters that fit around extrusion and injection-molding barrels. All require a temperature switch or controller (sold separately) to regulate heat output.

Note: The heater must be sized to fit tightly around the barrel to prevent air gaps that lead to inefficient heating and premature failure.

Pipe Cradles for Loop Hangers

Adhesive Mount

Also known as pipe shields, these cradles provide additional support and prevent insulation from tearing when routing insulated pipe through loop hangers.

Adhesive-mount cradles have an adhesive strip that attaches the cradle to the pipe’s insulation.
