Product Introduction：
The corrugated conduit waterproof connector is a sealing cable entry accessory designed for plastic corrugated conduit systems, primarily used to create a watertight connection between corrugated conduits and electrical equipment, control cabinets, junction boxes, or other fittings. When cable harnesses need to pass through damp, splash‑prone, or outdoor environments, standard conduit fittings often fail to prevent water ingress along the conduit wall or through thread gaps. This waterproof connector solves the problem by incorporating an integral sealing ring and a specially designed structure that provides a reliable radial seal between the corrugated conduit’s outer wall and the connector body. Meanwhile, the locknut at the tail of the connector can be tightened firmly against the equipment panel, effectively preventing water, oil, and dust from entering the enclosure, thereby achieving a high degree of ingress protection.
The connector body is typically made of reinforced nylon PA66, offering good mechanical strength and chemical resistance for long‑term use in harsh conditions. The sealing component is produced from aging‑resistant and hydrolysis‑resistant NBR or EPDM rubber, ensuring stable sealing performance even under prolonged immersion or significant temperature fluctuations. The protection rating usually reaches IP68, meaning the connector can function properly when continuously submerged. It also provides strong resistance to impact and vibration. The operating temperature range is generally from -40°C to +125°C, making it suitable for a wide variety of applications, from freezing outdoor environments to locations near high‑temperature equipment.
In terms of installation, the corrugated conduit waterproof connector uses a threaded tightening structure. The user simply inserts the conduit into the connector and then tightens the back nut. As the nut is tightened, it compresses the internal tapered sealing ring, which in turn grips the outer wall of the corrugated conduit firmly. No additional sealant or waterproof tape is required. For removal, loosening the nut allows the conduit to be pulled out easily, facilitating maintenance and cable replacement. The connector is available in multiple thread sizes, such as metric (M12, M16, M20, M25, M32, etc.) and PG series, to fit different equipment cutouts. Corresponding conduit sizes range from AD10.0 to AD54.5, allowing users to choose the right version based on cable bundle diameter and installation space.
Corrugated conduit waterproof connectors are widely used in outdoor lighting equipment, photovoltaic inverters, marine electrical systems, EV charging stations, outdoor enclosures, and various automation devices that must operate in damp or dusty environments. They effectively ensure long‑term reliability of electrical connections, preventing short circuits and corrosion, and are an indispensable component in waterproof cable protection systems.
