FRÄNKISCHE ROHRWERKE SMSKu-E 25 acoplamiento de enchufe gris para tubos protectores M25

Electricians and panel builders working with rigid conduits need a reliable, tool-free way to join M25 conduit sections. The FRÄNKISCHE ROHRWERKE SMSKu-E 25 push-fit coupling slides over the conduit ends and locks them together in seconds, creating a secure, IP65-rated connection that stands up to dust, water jets, and everyday knocks. Its grey polypropylene body blends into almost any installation, from machine wiring to outdoor cable runs.

Key specifications

• Product type: Conduit coupling with push-fit connection
• Nominal diameter: M25 (suitable for NW25 conduits)
• Material: Halogen-free polypropylene (PP), light grey RAL 7035
• Protection class: IP65 (dust-tight and protected against water jets)
• Mechanical strength: Compression class 3 (750 N), impact class 3 (2 J)
• Temperature range: -25 °C to +60 °C
• UV resistant: Yes, suitable for outdoor use
• Standards: EN 61386-22

Why choose it

No screws, no glue, no special tools. The push-fit design reduces installation time and eliminates the risk of loose connections. The halogen-free material is a safer choice in case of fire, and the IP65 rating means you can use it in damp or dusty environments without extra sealing. The grey colour matches standard conduit systems, keeping the installation looking clean and professional.

Ideal use cases

• Joining rigid conduit sections in industrial control panels
• Extending conduit runs in outdoor or washdown areas
• Repairing damaged conduit without replacing the whole length
• Creating a fixed point in a conduit system where a junction is needed

Good to know

The coupling is intended for rigid conduits only and should not be used with flexible or corrugated conduit. Always check that the conduit outer diameter matches the M25 nominal size before installation. For best results, cut the conduit ends square and deburr them before pushing into the coupling.
