Hose clamp Topex 37D501, worm gear clamp, adjustable 8–12 mm

Topex 37D501 is a worm gear hose clamp designed to secure hoses and small-diameter pipes with diameters from 8 to 12 mm. The clamp features an adjustable metal band and a threaded screw mechanism that enables precise tightening and even pressure distribution around the hose. It is intended for light- to medium-duty assembly and repair tasks in plumbing, automotive systems, and general maintenance where a compact, adjustable clamp is required.

Advantages

The worm gear design provides consistent, incremental tightening for a reliable seal without slipping. Its compact size fits confined spaces while the steel construction offers durability and resistance to deformation under moderate loads. The adjustable range of 8–12 mm makes the clamp versatile for different hose types and fittings, and the screw head accepts common driver tools for quick installation and adjustment.

Suitable for

• Securing coolant, vacuum or fuel hoses in small engines and machinery
• Plumbing connections on small-diameter pipes and flexible tubes
• General repair and maintenance tasks requiring a compact adjustable clamp

Key specifications

• Clamping range: 8–12 mm (diameter)
• Type: worm gear (screw) hose clamp
• Material: metal band with threaded screw mechanism
• Intended duty: light to medium
• Suitable for confined or tight installation spaces

How to use

Place the clamp over the hose end and position it so the band sits evenly around the hose and the screw housing is accessible. Using a compatible screwdriver or nut driver, turn the screw clockwise to tighten until the hose is firmly seated on the fitting and a leak-free seal is achieved. To remove or adjust, turn the screw counterclockwise. Ensure the clamp is not over-tightened to avoid damaging the hose or compressing internal passages.

Usage recommendations

Use the clamp within its specified 8–12 mm diameter range and check compatibility with hose material. For applications involving high pressure, corrosive environments, or heavy vibration, consider a higher-duty or specialized clamp. Inspect clamps periodically for corrosion, loosening, or wear and replace if deformation or loss of holding force is observed.
