20mm Galvanised Conduit Coupler | Threaded Steel Connector

Galvanised conduit systems have been a staple of UK factories and workshops for decades, valued for their strength, durability, and no-nonsense industrial aesthetic. Today, that same look is increasingly used in bars, restaurants, hotels, and contemporary homes to achieve a clean, urban finish.

Our 20mm galvanised conduit coupler is designed to securely join two lengths of threaded 20mm conduit, creating a strong, seamless connection. Manufactured from steel and finished in traditional galvanised coating, it delivers both long-term performance and an authentic industrial appearance.

Compatible with our cut and threaded 20mm galvanised conduit, this coupler makes installation straightforward—no specialist tools required. Ideal for lighting installations, surface-mounted electrical runs, and industrial-style interiors.
