M25 Brass Nickel-Plated Cable Gland (Waterproof Connector)
Zhejiang Zhengna Technology Co., Ltd. supplies high-precision, custom-manufactured M25 Brass Nickel-Plated Cable Glands. This essential component, also known as a cord grip or strain relief connector, is engineered to provide a secure, watertight, and dust-tight seal where cables or hoses enter enclosures, machinery, or control panels.
Constructed from solid brass and finished with a durable nickel plating, our cable gland offers superior resistance to corrosion, oxidation, and harsh environmental conditions. The precision CNC machining ensures perfect threads (M25 x 1.5mm metric thread standard) and reliable sealing, making it a critical part for ensuring electrical safety and system integrity.
Key Features & Benefits
-
Robust & Durable Construction: Made from high-grade brass, providing excellent mechanical strength and longevity.
-
Superior Corrosion Protection: Bright nickel plating offers enhanced resistance to rust, tarnishing, and chemical exposure, ideal for marine, industrial, and outdoor use.
-
High Ingress Protection (IP68): Designed to reliably seal out dust and withstand prolonged immersion underwater, protecting sensitive internal components.
-
Precision Machined Threads: CNC-machined M25 threads ensure a smooth, accurate fit with locknuts and enclosures, preventing cross-threading and ensuring a tight seal.
-
Secure Cable Retention: The internal neoprene sealing gland and compression nut provide excellent strain relief, preventing cable pull-out and protecting connection points.
-
Wide Compatibility: Suitable for a broad range of cable diameters. Commonly used in electrical cabinets, LED lighting, marine equipment, HVAC systems, and automation machinery.
