Hose Clamp Topex 37D508, worm gear clamp, size 40–60 mm, stainless steel W2

Topex 37D508 worm gear hose clamp secures hoses and flexible tubing with an adjustable diameter range of 40–60 mm. Constructed to W2 corrosion-resistance standard, this clamp has a stainless steel band and housing with a worm drive screw that provides consistent clamping torque. It is designed for plumbing, automotive hose connections, HVAC installations and general repair tasks where a stable, adjustable clamp is required.

Advantages

The worm gear design enables precise adjustment and reliable holding force across the full 40–60 mm range. W2 stainless steel components reduce corrosion risk in wet and mildly corrosive environments while keeping costs lower than higher-resistance stainless grades. The band width and screw thread provide even compression around hoses to minimize leaks and slippage. The simple screw drive allows easy tightening with a screwdriver or socket for fast installation and removal.

Suitable for

• Plumbing connections on water and drain lines
• Automotive coolant, air and vacuum hoses
• HVAC duct and flexible tubing joins
• General workshop and maintenance repairs

Key specifications

• Adjustable clamping range: 40–60 mm
• Material standard: W2 (stainless steel band and housing)
• Drive type: worm gear (screw drive)
• Typical use: hose and tubing fastening

How to use

Position the clamp over the hose end so the band sits evenly around the circumference and the worm screw is accessible. Tighten the screw clockwise using a flat-head screwdriver, Phillips screwdriver or compatible socket until the hose is compressed sufficiently to prevent leaks without deforming the hose. To remove or reposition, loosen the screw counterclockwise until the band relaxes and the clamp can be slid off. Verify the hose and connection remain properly seated while tightening to ensure an effective seal.

Usage recommendations

For longer service life, avoid continuous exposure to highly corrosive chemicals or seawater; for those environments consider higher stainless grades. Inspect clamps periodically in high-vibration or high-temperature applications and re-torque if necessary. Select the size range so the hose diameter falls well within 40–60 mm when tightened for optimal performance.
