Hose Clamp Topex 37D518, worm-drive, diameter 140–160 mm, corrosion class W2

Topex 37D518 worm-drive hose clamp is designed to secure hoses and ducts with a clamping range of 140–160 mm. Manufactured with a worm gear screw mechanism, the clamp allows controlled tightening and later readjustment. The W2 corrosion class indicates basic corrosion protection suitable for typical indoor and protected outdoor environments encountered in automotive, plumbing and HVAC installations.

Advantages

The worm-drive design provides even radial pressure around the hose, reducing the risk of leaks while enabling precise torque application during installation. The adjustable screw thread ensures a reliable connection across the specified diameter range of 140–160 mm. Materials and W2 corrosion protection balance durability and cost, making the clamp appropriate for medium-duty fastening tasks where full stainless performance is not required.

Suitable for

• Securing automotive radiator and coolant hoses
• Connecting flexible ducting in HVAC systems
• Plumbing connections on water and drainage lines in protected environments
• General workshop and repair tasks requiring medium-sized hose fastening

Key specifications

• Clamping range: 140–160 mm
• Drive type: worm gear screw
• Corrosion class: W2 (basic corrosion protection)
• Application: medium-duty hose and duct fastening

How to use

Place the clamp over the hose end and position the hose on the fitting or pipe. Align the band so the worm gear housing is accessible, then tighten the screw with a suitable screwdriver or nutdriver until the hose is evenly compressed and secure. Avoid excessive torque to prevent damage to the hose material; if re-adjustment is needed, loosen the screw, reposition the hose, and retighten to the recommended fit.

Usage recommendations

Inspect the connection after initial operation and periodically during use. For applications exposed to harsh weather, salt or chemicals, consider a clamp with higher corrosion resistance. Use the clamp only within the specified 140–160 mm range to ensure reliable performance.
