Tools & accessories: choosing the right clamp for a reliable installation

In the demanding world of marine electronics, a single detail can mean the difference between smooth sailing and critical failure. Often overlooked, cable ties ensure the secure fastening and watertightness of cables and hoses, guaranteeing the longevity of your system. Skysat, drawing on its extensive experience in offshore racing, guides you toward the most robust solutions tailored to your boat.

Types of collars and their applications

Choosing the right clamp depends on several factors: the type of fluid being transported (water, fuel, gas), the pressure, the temperature, and the diameter of the pipe or cable. An unsuitable clamp can lead to leaks, excessive vibration, and ultimately, system failure.

• Serflex hose clamps (worm screw type): Versatile and economical, they are suitable for many common applications, particularly for freshwater pipes and small-diameter electrical cables. Choose 316 stainless steel for better corrosion resistance.
• Crimp-on ear clamps: Offering superior sealing and increased vibration resistance, they are recommended for fuel and seawater systems, and applications where safety is paramount. A specific crimping tool is required for proper installation.
• Rilsan cable ties (plastic): Lightweight, insulating, and corrosion-resistant, they are ideal for securing electrical cables and harnesses. Check their UV resistance for outdoor use.
• High-pressure clamps: Designed for applications requiring exceptional pressure resistance (hydraulic circuits, engine cooling). Made of reinforced stainless steel, they guarantee a durable seal even under extreme conditions.

selection criteria and best practices

Before choosing a clamp, it is essential to consider the marine environment and the specific constraints of your installation. An incorrectly sized or poor-quality clamp can compromise the reliability of your entire electronic system.

• Material: Opt for 316 stainless steel for optimal resistance to marine corrosion. Avoid galvanized steel clamps, which rust quickly in a saline environment.
• Diameter: Ensure the clamp diameter perfectly matches that of the pipe or cable. A clamp that is too large or too small will not guarantee a proper seal.
• Tightening: Observe the tightening torque recommended by the manufacturer to avoid damaging the pipe or clamp. Use a torque wrench for precise tightening.
• Inspection: Regularly check the condition of the clamps and tighten them if necessary. Replace any rusty or damaged clamps.

💡 Skysat's advice

Don't hesitate to slightly oversize the clamp diameter, especially for flexible hoses that can expand with temperature changes. A slightly larger clamp will be easier to install and offer a better safety margin.
