## Long description

Topex 37D511 is an adjustable hose clamp with a 70–90 mm diameter range designed for secure fastening of hoses, pipes and duct connections. The clamp uses a screw tightening mechanism on a stainless-steel band and is produced to the W2 corrosion resistance standard, providing practical protection against rust in typical indoor and covered outdoor environments. It is intended for applications in automotive repair, plumbing and general maintenance where a compact, adjustable metal clamp is required.
Advantages
The clamp combines an adjustable stainless-steel band with a screw drive that allows reliable tightening across the 70–90 mm range. Construction to the W2 standard ensures improved corrosion resistance compared with uncoated clamps, while the compact profile and smooth band reduce the risk of hose damage during installation. The screw mechanism offers controlled torque and reusability for maintenance or repositioning.
Suitable for
 Securing automotive hoses and coolant lines within the specified diameter range
 Fastening plumbing connections and flexible pipes
 Joining ventilation ducts and flexible air hoses
 Temporary or permanent repair tasks requiring an adjustable metal clamp
Key specifications
 Adjustable diameter: 70–90 mm
 Material: stainless-steel band with screw tightening mechanism
 Corrosion resistance class: W2
 Clamping type: worm-drive / screw-tightened band
 Profile: low-profile smooth band suitable for flexible hoses
How to use
Position the clamp around the hose or pipe so the band sits evenly on the sealing area. Insert the hose onto the fitting or pipe and slide the clamp to the required position. Use a screwdriver or appropriate drive bit to turn the screw clockwise until the band is snug against the hose; avoid over-tightening to prevent hose deformation. To remove or reposition, turn the screw counterclockwise until the band loosens sufficiently, then slide the clamp off.
Usage recommendations
For best performance, select the clamp when the hose outer diameter falls within the 70–90 mm range. Inspect the clamped connection after initial use and periodically during service intervals. Avoid prolonged exposure to highly corrosive environments or direct saltwater contact, as W2 corrosion protection is intended for standard indoor and sheltered outdoor conditions. Use the clamp with compatible hose materials and fittings to ensure a reliable seal.
