Lapp SKINDICHT MA-PG 21 to M 20 x 1.5 Metal Thread Adapter

The Lapp SKINDICHT MA-PG 21 to M 20 x 1.5 metal thread adapter is a precision-engineered component designed to facilitate seamless transitions between different thread standards in electrical installations. This adapter allows for the reliable connection of equipment featuring PG 21 threads to systems utilizing M 20 x 1.5 metric threads, ensuring a secure and stable mechanical interface. Constructed from high-quality metal, this component provides excellent durability and resistance to environmental stressors, making it a dependable choice for demanding industrial environments.

Advantages

The primary advantage of this adapter lies in its robust metal construction, which offers superior mechanical strength and longevity compared to plastic alternatives. By enabling the conversion between PG and metric thread types, it provides essential flexibility for system upgrades, maintenance, or the integration of diverse electrical components. The precise threading ensures a tight fit, which is critical for maintaining the integrity of cable gland assemblies and preventing accidental loosening in vibration-prone settings.

Suitable for

• Industrial electrical control panels
• Machinery and equipment manufacturing
• Retrofitting existing electrical systems with new metric components
• Environments requiring high mechanical stability for cable entries

When it may not be suitable

This adapter is not intended for use in applications where non-metallic or specialized corrosion-resistant materials are strictly required, such as in certain highly acidic or chemical processing environments. It is also not suitable for installations where the thread sizes do not match the specified PG 21 or M 20 x 1.5 standards.

Key specifications

• Material: Nickel-plated brass
• External thread: PG 21
• Internal thread: M 20 x 1.5
• Quantity: 50 pieces per pack
• Design: Thread adapter for cable glands

How to use

To install the adapter, ensure that the target equipment is de-energized. Screw the PG 21 side of the adapter into the corresponding threaded hole or component. Once securely tightened, the M 20 x 1.5 metric cable gland or accessory can be threaded into the internal side of the adapter. Use appropriate tools to ensure the connection is firm, but avoid over-tightening to prevent damage to the threads.

What to consider before purchase

• Verify the thread standards of your existing equipment and the new components
• Ensure the installation space allows for the added length of the adapter
• Confirm that the material is compatible with your specific environmental conditions

Usage recommendations

Always verify that the threads are clean and free of debris before installation to ensure a smooth connection. For applications subject to high vibration, consider using an appropriate thread-locking compound or washer to maintain long-term security.
