Kokoelma: Clamps

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

In the demanding world of marine electronics, a small detail can make the difference between serene navigation and critical failure. Clamps, often overlooked, ensure the secure fastening and sealing of cables and hoses, thus guaranteeing the durability of your installation. Skysat, with its offshore racing experience, guides you towards the most robust and suitable solutions for your boat.

Types of clamps and their applications

The choice of a suitable clamp depends on several factors: the type of fluid transported (water, fuel, gas), pressure, temperature, and the diameter of the hose or cable. An unsuitable clamp can lead to leaks, excessive vibrations, and ultimately, installation failure.

• Hose clamps (worm drive): Versatile and economical, they are suitable for many common applications, especially for freshwater hoses and low-diameter electrical cables. Prefer 316 stainless steel for better corrosion resistance.
• O-ring clamps (crimping): Offering superior sealing and increased resistance to vibrations, they are recommended for fuel and seawater circuits and applications where safety is paramount. Require a specific crimping tool for correct installation.
• Rilsan clamps (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 durable sealing even in 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 improperly sized or low-quality clamp can compromise the reliability of your entire electronic system.

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

💡 Skysat's advice

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