FRAENKISCHE SM-E-V 20 Steel Threaded Coupling M20 for FFS-ES/FFSK-ES-UV Conduit, Galvanized 20450020

Electricians and panel builders connecting FRAENKISCHE FFS-ES or FFSK-ES-UV conduit systems rely on the SM-E-V 20 threaded coupling for secure, metallic continuity in industrial and outdoor installations. This galvanized steel coupling joins 20 mm conduits with metric M20 threads, ensuring a rigid, corrosion-resistant connection that withstands UV exposure and temperatures from -25°C to +120°C.

Key specifications

• Product type: Threaded coupling
• Material: Steel, galvanized
• Nominal conduit size: 20 mm
• Thread type: Metric M20
• Compatibility: FFS-ES, FFSK-ES-UV conduit systems
• Operating temperature: -25°C to +120°C
• UV resistant (for FFSK-ES-UV)
• Number of connections: 2

Why choose it

The zinc-nickel galvanized finish provides long-term corrosion protection in harsh environments, while the rigid steel construction maintains high mechanical strength. Its compatibility with UV-resistant conduits makes it suitable for outdoor electrical installations without additional protection.

Ideal use cases

• Industrial machinery wiring
• Outdoor conduit runs exposed to sunlight
• Connecting rigid steel conduits in demanding environments

Good to know
