Spring Hose Clamps

Spring Hose Clamps, also known as constant tension hose clamps, are designed to provide a consistent and reliable clamping force on hoses, particularly in applications where temperature fluctuations can cause expansion and contraction. Their spring steel construction allows them to automatically adjust their diameter to maintain a tight seal, preventing leaks due to thermal cycling or hose relaxation. These clamps are commonly used in automotive cooling systems, fuel lines, and various industrial and domestic applications where a self-adjusting and leak-proof seal is required.  

Features

• Constructed from spring steel for inherent elasticity and constant tension.
• Automatically adjusts diameter to compensate for hose expansion and contraction.
• Provides a consistent and reliable sealing force over a wide temperature range.
• Helps prevent leaks caused by thermal cycling and hose relaxation.
• Offers quick and easy installation and removal.
• Available in various sizes to fit different hose outer diameters.
• Often feature smooth, rounded edges to minimize hose damage.
• Provides a more uniform clamping pressure compared to traditional worm drive clamps in dynamic thermal environments.
• Cost-effective and maintenance-free.
• Suitable for applications where consistent sealing is critical.

Technical Data

• Material: Typically Spring Steel (e.g., 65Mn), Stainless Steel (e.g., 304)
• Inner Diameter Range: Available to fit various hose outer diameters (e.g., from 6mm to 100mm and beyond)
• Band Width: Common widths include 7mm, 9mm, 10mm, 12mm
• Wire Diameter (for wire-form clamps): Varies based on the clamp size and intended pressure
• Clamping Force Range: Dependent on the clamp size and material (refer to specific product specifications)
• Operating Temperature Range: Varies with the material used (e.g., Spring Steel: -40°C to +120°C, Stainless Steel: -50°C to +150°C or higher)
• Corrosion Resistance: Spring Steel with coating: Offers moderate corrosion resistance; Stainless Steel: Offers excellent corrosion resistance.
• Surface Finish: May have a protective coating (e.g., zinc plating) for spring steel or a natural finish for stainless steel.
• Installation Tool: Typically installed and removed using pliers or specialized clamp pliers.
• Application Examples: Automotive coolant hoses, fuel lines, vacuum lines, silicone hoses, low-pressure hydraulic hoses.
• Adjustment Range: The amount of diameter adjustment the spring action allows (varies by design).
