Hose Clamp Topex 37D510, worm-drive, size 60–80 mm, stainless steel W2

Topex 37D510 is a worm-drive hose clamp with an adjustable diameter range of 60–80 mm, manufactured in W2 stainless steel. The design features a slotted band and a captive screw that provides uniform radial pressure around hoses, pipes and flexible tubing. Its stainless-steel construction offers basic corrosion resistance suited to common automotive, plumbing and general repair environments where a reliable, adjustable fastening is required.

Advantages

The worm-drive mechanism allows precise tightening and quick adjustment with standard screwdrivers or nut drivers. The slotted band distributes clamping force evenly to reduce point loads on rubber or plastic hoses. W2 stainless-steel construction improves resistance to rust compared with plain steel, making the clamp suitable for use in damp or exposed conditions where occasional moisture is present. The size range covers many medium-diameter hose connections and the compact profile facilitates installation in constrained spaces.

Suitable for

• Securing coolant, air, or fuel hoses in automotive repairs and maintenance
• Clamping flexible tubing and pipes in plumbing and heating systems
• General workshop and DIY fastening where adjustable, corrosion-resistant clamps are needed

Key specifications

• Clamp type: worm-drive (slotted band with screw)
• Material: stainless steel, W2 grade
• Adjustable diameter: 60–80 mm
• Banding width: medium profile suitable for hose sealing (typical band width for the size range)
• Installation tool: compatible with flathead or hex screwdrivers/nut drivers

How to use

Position the clamp over the hose end and slide the hose onto the mating pipe or fitting. Place the slotted band so it sits evenly over the hose junction and engage the screw. Tighten the screw until the clamp provides a secure seal without crushing the hose; avoid over-tightening which can damage flexible materials. For larger assemblies, check the clamp after the first operation and re-torque if necessary to maintain a leak-free connection.

Usage recommendations

For best results, use a screwdriver or driver bit that matches the screw head to avoid stripping. Inspect the hose and mating surfaces for debris or sharp edges before installing the clamp. In highly corrosive environments or for long-term outdoor exposure, consider specifying a higher corrosion-resistance grade of stainless steel.
