Description
1. Product Overview
The Clifnor G-Series professional cable glands are engineered for high-integrity sealing in demanding industrial environments. Constructed from Nickel-Plated Brass with an integrated Nylon PA66 clamping claw, these glands provide exceptional strain relief and a permanent IP68 waterproof seal. The precision G-thread (PF/Gas thread) design ensures compatibility with standard industrial conduits and enclosures.

3. Advanced Engineering Features
-
Enhanced Clamping System: The optimized claw and seal design provides a wider cable clamping range while preventing core damage. The sealing nut features a distinct “Click” feedback mechanism to ensure a secure lock.
-
Double-Seal Integrity: Utilizing NBR for both the internal sealing insert and the external O-ring ensures gas-tight and liquid-tight performance even under 10-bar pressure.
-
Corrosion Resistance: The thick nickel plating provides a sacrificial layer against saltwater spray and harsh industrial atmospheric conditions, making it ideal for marine and offshore applications.
-
Mechanical Stability: Unlike plastic glands, the brass body prevents thread stripping and withstands high mechanical impacts or heavy cable loads.
4. Strategic Industry Applications
-
Marine & Offshore: Shipboard wiring, offshore platforms, and coastal lighting where salt-air corrosion is a primary concern.
-
Petrochemical & Mining: Connection points for sensors and power cables in environments exposed to oils, greases, and solvents.
-
Heavy Machinery: Vibration-resistant cable entry for industrial motors, generators, and control panels.
-
Food & Beverage: High-pressure washdown areas requiring IP68/10-bar ratings.
