Reliable PG21 Cable Entry and Protection for Electrical Installations
Cable glands are essential components in electrical installations, providing a secure transition between external cables and electrical enclosures. Correctly selected and installed cable glands help retain cables, reduce unwanted movement and minimise mechanical stress on internal electrical connections. They also support organised cable routing and help maintain the integrity of enclosure cable entry points.
The Partex DTGPG21BLK PG21 black nylon cable gland is designed for cables measuring 13–18 mm in outside diameter. Its nylon construction provides a lightweight, corrosion-resistant solution for electrical cable entry applications. The PG21 threaded design makes it particularly useful for compatible industrial equipment, electrical control cabinets and installations using traditional PG-threaded cable entry systems.
Unlike modern metric cable gland threads, PG21 uses the Panzergewinde thread system and should not be treated as interchangeable with M25 or other metric thread sizes. Correct thread compatibility, cable diameter selection and installation tightening are important for reliable cable retention. Where a particular ingress protection rating is required, the complete gland, sealing arrangement and enclosure assembly should be checked against the installation requirements.
Typical Applications
- Industrial electrical control panels and automation cabinets.
- Electrical junction boxes with PG21 cable entry openings.
- Industrial machinery and manufacturing equipment.
- Electrical distribution cabinets and equipment enclosures.
- Commercial and industrial electrical installations.
- Maintenance and refurbishment of existing PG-threaded equipment.
- Power and control cable entry applications.
- OEM machinery manufacturing and control panel assembly.
- Electrical maintenance, repairs and replacement cable gland installations.
