Hose clamp GEKO W1 9 mm, adjustable diameter 200–220 mm

GEKO W1 9 mm hose clamp with an adjustable diameter range of 200–220 mm is engineered to secure hoses, pipes and ducting in automotive, plumbing and light industrial settings. The clamp features a 9 mm wide stainless-style band conforming to corrosion resistance class W1 and a simple worm-drive screw for straightforward tightening and release. Its medium-duty design offers consistent clamping force across the specified diameter range and is suitable for applications that require basic resistance to corrosion and dependable mechanical fastening.

Advantages

The GEKO W1 clamp combines a 9 mm band width with a worm-drive screw for accurate, tool-assisted adjustment and secure retention. Corrosion resistance class W1 provides basic protection against rust in non-aggressive environments while the 200–220 mm adjustable range covers a variety of hose and duct diameters. Its construction enables repeated installation and removal without significant loss of clamping performance and the smooth band profile reduces the risk of damage to hose surfaces.

Suitable for

• Securing automotive coolant, air and vacuum hoses
• Fastening plumbing pipes and flexible ducting
• Light industrial and workshop applications with medium‑duty requirements
• Temporary or repeated connections where adjustable clamping is needed

Key specifications

• Band width: 9 mm
• Adjustable diameter range: 200–220 mm
• Clamping mechanism: worm-drive screw
• Corrosion resistance class: W1 (basic corrosion protection)
• Material: stainless-style band and screw suitable for general-purpose use
• Duty level: medium-duty fastening

How to use

Place the clamp around the hose or duct so that the band sits evenly on the sealing surface. Rotate the worm-drive screw clockwise using an appropriate screwdriver or socket until the clamp provides firm, even pressure without deforming the hose. To remove or loosen, turn the screw counterclockwise. Inspect the clamped joint after initial operation and retighten if necessary to maintain a secure seal. Replace the clamp if the band or screw shows visible wear or corrosion that compromises performance.

Usage recommendations

Use this GEKO W1 clamp where basic corrosion resistance and medium-duty securing are sufficient. Avoid prolonged exposure to highly corrosive environments or continuous high-temperature conditions. For critical or marine applications, choose a clamp with higher corrosion class. Ensure correct band alignment and avoid overtightening to prevent hose damage.
