## Long description

Norma worm-gear hose clamp with adjustable diameter from 80 to 100 mm. Constructed from stainless steel, this clamp is designed to provide secure radial sealing for hoses, ducts and tubing in automotive, plumbing and light industrial applications. The slotted band and captive screw allow consistent torque transfer and straightforward tightening using a screwdriver or nut driver, ensuring stable hose connections under moderate pressure and vibration.
Advantages
The stainless steel construction offers corrosion resistance and dimensional stability in damp or mildly corrosive environments. The worm-gear mechanism permits fine adjustment across the 80–100 mm range for a reliable fit on a variety of hose diameters. A captive screw reduces the risk of fastener loss during installation and simplifies repetitive assembly or maintenance tasks.
Suitable for
 Securing rubber and reinforced hoses in automotive cooling and intake systems
 Connecting flexible ducting in ventilation and HVAC systems
 Clamping hoses and tubing in residential and commercial plumbing
 Light industrial applications where moderate axial and radial loads are present
Key specifications
 Material: stainless steel band and housing
 Clamping range: 80–100 mm (diameter)
 Closure type: worm-gear with slotted band
 Screw type: captive screw compatible with screwdriver or nut driver
 Application: radial hose sealing for hoses, ducts and tubing
How to use
Position the clamp around the hose over the fitting or barb, align the slotted band evenly, and hand-tighten the captive screw until the band contacts the hose. Use a screwdriver or nut driver to tighten further, applying even turns until a secure seal is achieved without over-torquing. Check alignment and seating of the hose on the fitting after tightening and re-torque as needed following initial operation or exposure to temperature cycles.
Usage recommendations
For durable connections, select the clamp so the required operating diameter falls well within the 80–100 mm range. Avoid excessive torque to prevent hose deformation; use a calibrated torque screwdriver where precise tightening is required. Inspect clamps periodically for corrosion, loss of tension, or damage, and replace if signs of failure appear.
