Plastic hose clamps are lightweight, corrosion-resistant assembly hardware designed to secure hoses onto fittings in low-pressure applications. Constructed from durable polyamide (nylon), these hose clamps feature an interlocking serrated mechanism that provides a secure grip without the need for additional tools.
Their non-conductive and non-corrosive properties make them ideal for use in environments where metal clamps may not be suitable. Common applications include fluid transfer systems, cable management and securing hoses in industrial machinery.​
How Plastic Hose Clips Work
These plastic clamps for hoses operate using an interlocking ladder mechanism. The clamp is wrapped around the hose and the serrated ends are interlocked to tighten, similar to a cable tie. As the clamp is tightened, the serrations engage step by step to maintain tension, ensuring a secure fit around the hose.
This design allows for quick installation without the need for specialised tools. However, it's important to note that plastic hose clips are not suitable for pressurised systems due to their clamping limitations.​ For this, we'd recommend taking a look at our t-bolt clamps.
Materials Plastic Hose Clamps Are Made From
Our range of plastic hose clamps is made from polyamide (nylon), chosen for its strength, flexibility and resistance to various chemicals and environmental factors.​ Nylon hose clamps offer excellent mechanical properties, including high tensile strength and impact resistance. They also provide good resistance to abrasion and chemicals, making them suitable for various industrial applications.​
Sizes and Types of Plastic Hose Clamps Available
Accu offers a range of sizes and colours to accommodate different hose diameters and application requirements, from small plastic hose clamps to white and black nylon hose clamps.
- Hose Diameter Range: 6mm to 90mm
- Colours: Black, White & Grey​
These variations allow for easy identification and compatibility with different systems and environments.​
FAQs
Q: How to tighten a plastic hose clamp?
A: To tighten a plastic hose clamp, wrap it around the hose and insert the two interlocking serrated ends together. Press on both sides of the clamp until the two sides fit snugly around the hose. Ensure not to overtighten, as this may damage the clamp or hose.​ Try to also avoid using tools, as these could also break the clamp.
Q: Can plastic hose clamps be reused?
A: While some plastic hose clamps are designed for single use, others can be reused if they have not been damaged during removal. Always inspect the clamp for wear or damage before reusing.​
Q: Are plastic hose clamps suitable for outdoor use?
A: Yes, our plastic hose clamps made from polyamide are resistant to UV radiation and various environmental factors, making them suitable for outdoor applications.​
Q: What are the advantages of using plastic hose clamps over metal ones?
A: Plastic hose clamps are non-conductive, corrosion-resistant and lightweight, making them ideal for applications where metal clamps may cause issues, such as in electrical or corrosive environments.​
