Hose Clamp Topex 37D514, worm-drive, diameter 100–120 mm, corrosion resistance class W2

The Topex 37D514 worm-drive hose clamp secures hoses and ducts with diameters from 100 to 120 mm. Manufactured to a W2 corrosion resistance class, this clamp features a threaded screw mechanism that provides adjustable tightening and a consistent seal across the clamped surface. The design suits applications where medium corrosion protection and repeatable adjustment are required, delivering a simple mechanical solution for hose connections in automotive, plumbing and ventilation systems.

Advantages

The worm-drive construction ensures gradual, precise tightening and easy adjustment with standard tools. W2 corrosion resistance provides moderate protection against atmospheric corrosion, extending service life compared with non-treated clamps. The wide diameter range of 100–120 mm accommodates various hose wall thicknesses and materials, while the stainless-treated screw and plated band reduce the risk of seizing and permit multiple reuses when maintained properly.

Suitable for

• Automotive intake, coolant or vacuum hoses
• Plumbing connections and flexible pipe joints
• Ventilation ducts and HVAC flexible hose connections
• General repair and maintenance where adjustable clamping is needed

Key specifications

• Clamping type: worm-drive screw mechanism
• Applicable diameter range: 100–120 mm
• Corrosion resistance class: W2 (moderate protection)
• Material characteristics: plated band with treated screw for reduced seizing
• Adjustment method: screw-tightening with screwdriver or socket

How to use

Position the clamp around the hose so the band sits evenly over the connection interface. Start with the screw relaxed, then advance the screw gradually while ensuring the hose remains properly seated on the fitting. Tighten until a secure seal is achieved without deforming the hose; avoid overtightening to prevent damage to soft materials. Check the connection after initial operation and re-tighten if necessary to maintain a leak-free joint.

Usage recommendations

For best performance, inspect clamps periodically for corrosion or thread wear, especially in humid or chemically aggressive environments. Replace clamps that show significant corrosion or stripped threads. Use the clamp within its specified diameter range and select a higher corrosion class for long-term outdoor or marine exposure.
