ASTM Alumina Ceramic Insulator Sealed Ceramic Ring For Battery

Alumina Ceramic Insulator /Electrical Insulation Rod For Oxygen Sensor


1. Description:

Stronger than standard firebricks but with lower insulation capabilities, these withstand heavy abrasion on the floors and sides of furnaces. They meet ASTM standards for flame resistance. Also known as hard firebricks. Cut with a diamond-tipped tile saw and install with firebrick bonding mortar (sold separately).

Unlike fiberglass and silica, this sleeving won't irritate skin, so it’s easier to handle. It withstands open flame and molten metal splash, making it a good choice for welding applications. The ceramic fabric also resists acids, alkalies, alcohol, solvents, oil, and gasoline. 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. It meets MIL-I-24244 for material quality.
