Spring hose clamp Alphacool 68084, black, brass construction, spring clamp for hoses

Spring hose clamp Alphacool 68084 is a black, brass-constructed spring clamp designed to secure hoses and flexible tubing. It provides consistent radial pressure via a spring mechanism, making it suitable for coolant, water or air lines where a compact and reusable fastening is required. The clamp is made from steel tape with brass elements, compatible with hoses with an outer diameter of 13 to 15 mm, and intended for hose fixation on fittings without union nuts.

Advantages

The spring design ensures uniform clamping force around the hose for reliable sealing and reduced risk of leaks. Its compact profile is well suited for tight installation spaces, and the steel tape construction with brass components offers durability and resistance to deformation. The clamp can be reopened and closed multiple times while retaining its clamping force, and it can be operated by hand or more easily with pliers for secure attachment.

Suitable for

• PC water-cooling loops and custom liquid cooling systems
• Small plumbing repairs and flexible tubing connections
• Air and coolant lines in electronic or mechanical assemblies
• Hose fixation on barbed fittings without union nuts

Key specifications

• Material: steel tape with brass construction and spring mechanism
• Finish: black
• Compatible hose outer diameter: 13–15 mm
• Clamp type: spring / constant-tension hose clamp
• Reusable: yes, retains clamping force after multiple openings

How to use

Slide the clamp over the hose before attaching the hose to the fitting. Position the clamp directly over the barbed section of the fitting and compress the clamp to expand its diameter, then release to apply uniform radial pressure. For easier operation, use pliers to open the clamp, ensuring it sits squarely and firmly on the hose. Verify the clamp is seated correctly and test the connection under normal operating conditions to confirm there are no leaks.

Usage recommendations

Use the clamp within its compatible hose diameter range (13–15 mm) and avoid overtightening by deforming the hose. Inspect clamps periodically in systems with temperature or pressure cycling to ensure continued sealing performance. For corrosive environments, verify material compatibility before prolonged use.
