These Radium Engineering insulator boots slip over a ring terminal and its acorn nut to shield the connection from shorts and corrosion. They are molded from Shore 60A vinyl in black, measure 27mm long by 14mm wide by 18mm tall, and carry a 5.5mm bore for the wire alongside an 11mm bore for the acorn nut. They are compatible with all Radium Engineering fuel hats that use stainless steel electrical terminals, and ship five to a pack.
