Coupling HiSmart M18 EL240036 — hydraulic/industrial coupling M18 thread

Coupling HiSmart M18 EL240036 is a threaded M18 coupling made from high-strength brass alloy for grounding, lightning protection and industrial hydraulic applications. The coupling provides a secure screw-type M18 connection to join rods, driving heads or threaded fittings, allowing extension of rod length while protecting ground rod threads from damage and slowing corrosion.

Advantages

The coupling is manufactured from a high-strength copper/brass alloy for improved mechanical durability and corrosion resistance. Its M18 screw thread ensures reliable, easy assembly and a stable mechanical and electrical connection in grounding and hydraulic systems. Compact dimensions and a moderate weight make it suitable for workshop and field use.

Suitable for

• Connecting ground rods and rod-to-head assemblies
• Extending rod length by joining multiple rods
• Use in grounding and lightning protection systems
• Industrial and hydraulic threaded M18 connections in maintenance and repair tasks

Key specifications

• Material: brass (high-strength copper alloy)
• Rod diameter: 16 mm
• Screw type: M18
• Length: 68 mm
• Outer diameter: 22 mm
• Weight: 111 g

How to use

Thread the coupling onto the M18 male thread of a rod or driving head by hand, then tighten securely with appropriate tools to ensure a firm mechanical and electrical connection. To extend a rod, join two rods by threading each rod end into opposite sides of the coupling until fully engaged. Ensure threads are clean and undamaged before assembly to prevent cross-threading and to maintain electrical continuity.

Usage recommendations

For grounding and lightning protection applications, verify compatibility with the rod material and system requirements. Inspect threads regularly for corrosion or wear and retighten after initial installation if necessary. Avoid using damaged or severely corroded couplings to maintain reliable mechanical and electrical performance.
