Heyco Heyco-Flex™ Liquid-Tight Tubings are flexible, non-metallic, and corrugated tubings for trade sizes 3/8" through 1". These tubings resist corrosion, oil, and water and are nontoxic, UV-resistant, and flame-retardant. The Heyco-Flex™ liquid-tight tubings offer quick and easy installation, maximum flexibility, and can be used in extremely tight quarters. These tubings do not require threading for installation, which eliminates the possibility of cutting the tubing and creating leak paths. The Heyco-Flex™ liquid-tight tubings support a 300V voltage rating and are rated for NEMA type 3R, 4, and 4X applications. These tubings are suitable for high-vibration or flexing applications such as automotive equipment, fiber optics, computer and peripherals, lab equipment, and robotics.
