Overview – ALCO Type Brass Gland (G Type)
The Brass G Type Gland is a compression type cable gland primarily used for securing and sealing cables entering electrical equipment. It is commonly referred to as ALCO Type due to its design configuration. These glands provide effective strain relief, dust protection, and vibration resistance, making them suitable for indoor and moderate outdoor applications.
Key Features:
Compression type cable sealing
Strong mechanical cable retention
Suitable for unarmoured cables
Corrosion-resistant Brass body
Easy installation and maintenance
Available in Metric, BSP, NPT threads
Compatible with industrial enclosures
