Thread Converters/Adapters

Thread Converters/Adapters

Thread converters/adapters are specialized fittings used in electrical installations to join conduit components with different thread types or sizes. These converters allow for a seamless and secure connection between conduit fittings, junction boxes, or other electrical components that may have incompatible threads.

The design of Thread converters/adapters typically involves a male-threaded end on one side and a female-threaded end on the other side. The male-threaded end is designed to fit into the female threads of one conduit component, while the female-threaded end accommodates the male threads of another component with different sizing or threading.

Key features and advantages of Brass conduit thread converters/adapters include:

  1. Electrical Conductivity:Brass is an excellent conductor of electricity, ensuring electrical continuity in the conduit system.
  2. Corrosion Resistance:Brass thread converters/adapters are designed to resist corrosion, making them suitable for outdoor and indoor electrical installations.
  3. Mechanical Strength:Brass provides sturdy and reliable connections, ensuring the longevity and integrity of the electrical conduit system.
  4. Compatibility:Brass conduit thread converters/adapters allow for the connection of various conduit components, such as connectors, couplings, and nipples, with different thread types or sizes.


Common applications of Brass conduit fittings thread converters/adapters include:

  • Connecting conduit connectors or couplings with different thread sizes.
  • Adapting conduit fittings to junction boxes or electrical enclosures with varying thread types.
  • Joining conduit components from different manufacturers with incompatible threading.


When using Brass conduit fittings thread converters/adapters, it’s crucial to select the appropriate converter that matches the specific thread types and sizes of the conduit components being connected. Improperly matched thread converters/adapters can lead to loose connections or potential hazards.

Brass and stainless steel thread Adapters / Reduces help users with dissimilar thread sizes. Blanking plugs are used to stop and seal conducts and pipes. also a range of thread accessories link Fiber / Rubber Washers / Seals can be provided.
