2-Pack Ceramic Insulating Rods – High-Strength Alumina Tubes, Length 300mm, Outer 40mm, Inner 30mm – For Electrical & Heating Applications

About This Product

If you're working with high-temperature equipment, electrical systems, or laboratory setups, these ceramic insulating rods are built to handle the heat.

This is a 2-pack of alumina ceramic tubes – each one is 300mm long, with an outer diameter of 40mm and an inner diameter of 30mm.

High-alumina content gives them excellent electrical insulation properties – high dielectric strength and low loss, so they're reliable in demanding environments.

They're also tough – high fracture resistance means they can handle mechanical stress without cracking, which is critical when they're used as protective sheaths, heater rod covers, or circuit breakers.

They resist heat and corrosion, so they last longer than cheaper alternatives.

Widely used in electric heating elements, power distribution systems, and lab test rigs.

If you need durable, high-performance ceramic tubes for industrial or experimental work, these are a solid choice.

Two pieces per pack means you have a spare or can use them in parallel setups.

Just make sure you've got the right dimensions for your fixture.
