Heyco® Break-Thru™ Skinned-Over glands offer flexible sealing options by allowing fewer holes while maintaining a liquid-tight seal around conductors. They feature an integral sealing ring for a superior seal at mounting points. These glands are IP 68 rated and approved for NEMA 4, 4X, 6, and 6P environments. Made of durable nylon with TPE sealing glands, they resist exposure to salt water, weak acids, gasoline, alcohol, oil, grease, and common solvents. Multi-hole glands provide a wide range of conductor through-hole sizes and configurations, many with specific agency approvals. These glands are designed for use with Heyco Liquid Tight Cordgrips and are not sold separately.
