## Summary description

Topex 37D509 is a worm-gear hose clamp for securing hoses and pipes with a 50–70 mm diameter range. Constructed to W2 corrosion-resistance level, it features an adjustable band and threaded screw for reliable tightening. Suitable for automotive, plumbing and general repair tasks where a compact, adjustable metal clamp is required to ensure secure hose connections.

## Long description

Topex 37D509 is a worm-gear hose clamp designed for securing hoses and pipes with diameters from 50 to 70 mm. The clamp has an adjustable metal band and a threaded screw mechanism that provides gradual, controlled tightening. Built to a W2 corrosion-resistance level, the clamp is suitable for environments where occasional moisture or mild corrosion may occur. Its compact profile allows installation in confined spaces and delivers a uniform clamping force around flexible and semi-rigid hoses.
Advantages
The worm-gear drive enables precise adjustment and reliable holding power without slippage. W2-rated materials provide improved resistance to corrosion compared with plain steel clamps, extending service life in non-aggressive conditions. The smooth band edges help reduce damage to hose material during installation while the compact housing minimises protrusion. The clamp’s simple screw mechanism requires only common hand tools for fitting and removal.
Suitable for
Securing coolant, air and fuel hoses in automotive and small-engine applications
Plumbing connections on flexible hoses and boot seals
General repair and maintenance tasks where a compact adjustable metal clamp is needed
Temporary or permanent hose joins in workshop and light industrial settings
Key specifications
Type: worm-gear (screw) hose clamp
Diameter range: 50–70 mm
Material/finish: W2 corrosion-resistance level (zinc-plated steel components)
Band width: suitable for medium-duty hose applications
Operation: threaded screw for incremental tightening and loosening
How to use
Position the clamp around the hose where it overlaps the fitting or ferrule and ensure the band seats evenly. Turn the screw clockwise with a screwdriver or compatible socket to tighten until the hose is compressed sufficiently to prevent leaks, taking care not to over-tighten and distort the hose. To remove or reposition, turn the screw counterclockwise until the band can be slid off. Inspect the hose and clamp seating after initial operation and retighten if necessary.
Usage recommendations
For reliable results, select the clamp size so that the hose sits near the middle of the 50–70 mm range when fitted. Avoid overtightening on soft or thin-walled hoses; use a torque-limited driver if precise clamping pressure is required. In corrosive or marine environments, consider a higher corrosion-resistance class or stainless-steel alternative.
