C & M Rubber Co. manufactures four sizes of electrical terminal boots used in products requiring a physical protective cover for electrical terminal posts. Originally designed and predominantly used in the aerospace market, these parts have proven to be a cost-effective off-the-shelf solution for a host of electrical connector applications such as marine batteries, hot tubs, gas-powered residential and farm equipment, and electronic telephone switches to name just a few.

Using rubber silicone Class II, 50 Duro (Shore A) per MIL-R-5847, the terminal boot is manufactured using liquid injection molding (LIM) systems. They are then batch processed in a cryogenic de-flashing system to yield a “whistle clean” finish. Visual in-process and post-process inspections are used to ensure your delivered parts meet Mil-Spec AA-59178 (superseded MS-25171 Mil-Spec).

These terminal boots tolerate temperatures from -85 to 401°F and are resistant to environmental exposure. C & M Rubber manufactures these terminal boots in four standard sizes and certifies them to AA-59178-1, -2, -3, and -4 standards (detailed below). The standard color is white, however, they can be specified in black and brick red. Lead-time for standard colors in quantities less than 20,000 pieces is typically 3 weeks or sooner (ARO) depending upon current in-house order cue. Custom colors are also available at a minimum upcharge and a slightly longer lead-time depending on quantity and schedule requirements.
