Across industries such as home automation, factory monitoring, and sensor integration, the Plastic Cable Gland has become a reliable choice for cable entry protection. Whether in modular junction boxes or distributed control units, the Plastic Cable Gland ensures that cables are securely fastened, sealed, and protected against dust, moisture, and strain. Zhejiang Hongjuesi Connectors (HJSI) offers a series of plastic glands that balance cost, convenience, and technical performance.

Plastic glands are often selected over metal types in applications where weight, electrical isolation, or chemical exposure is a concern. HJSI’s glands are made from industrial-grade polyamide that offers excellent tensile strength, self-extinguishing properties (usually UL94 V-2 or better), and stable geometry under thermal cycling. This makes them suitable for indoor machinery, data boxes, robotics arms, and HVAC sensor units where continuous movement or space limitation requires compact fittings.

One of the biggest functional advantages is the gland’s ability to maintain cable alignment and reduce pull force on terminals inside enclosures. The sealing insert inside each gland, typically made of nitrile or EPDM, conforms tightly to the cable’s outer jacket while the dome nut applies uniform pressure. This compression helps prevent accidental disconnections or water ingress even under slight movement or vibration.

HJSI provides a broad array of thread types including M, PG, and NPT for easy integration into global system designs. These plastic glands come in varied clamping ranges—from micro-sensor wires under 3mm to thick power cables up to 40mm. All units are factory-tested to comply with IP65–IP68 standards, depending on model and installation quality.

For commercial electronics or digital displays mounted in public areas, appearance also matters. Plastic cable glands offer a visually clean finish and can be produced in matching panel colors. HJSI provides options in black, white, and light gray as standard, and supports custom color requests in volume orders. This helps OEMs create streamlined, brand-consistent panel appearances.

Another feature engineers appreciate is the dielectric isolation of plastic glands. In circuits where multiple voltages or sensitive signals exist, eliminating conductive components from gland interfaces helps prevent unintended grounding or interference. For example, in control panels with both power and data cables, using plastic glands helps maintain electrical segregation between pathways.

Despite being lightweight, HJSI’s plastic glands are designed to resist minor impact and withstand environmental wear. They hold their structure under sunlight exposure (UV-stabilized variants available), mild chemical fumes, and ambient temperature shifts between -20°C and +100°C. The threads and compression nut are reinforced to prevent stripping, even under repeated tightening.

Installation is straightforward—no special tools are needed beyond standard hex wrenches. HJSI glands are delivered in individually bagged or bulk formats with optional sealing washers, locknuts, and assembly instructions. Technical data sheets for each product series outline torque values, thread specs, and clamping charts to support electrical contractors and project designers.
