Tork Craft Heavy Duty Hose Clamp — 122-146 mm (Model HC122-146)
This robust worm-drive hose clamp securely fastens hoses, flexible ducting or tubing with outside diameters from 122 mm to
146 mm. Built for strength and reliability, it’s suitable for HVAC, plumbing, automotive and industrial applications.
Extra Information
Ensure mating surfaces and hose are clean and free of debris before applying clamp
Avoid over-tightening — torque until hose slightly compresses or sealing begins
Inspect clamp periodically in applications with vibration or thermal cycling to maintain tightness
Check that screw threads and clamp alignment are correct before applying full torque to prevent damage or thread stripping
Pro Tip
Use a dab of lubricant on the screw threads to smooth tightening and reduce galling risk
Position the screw housing away from potential abrasion or moving parts for longer hose life
Features
Clamping range: 122 – 146 mm
Worm drive screw mechanism — precise, adjustable tightening force
Heavy gauge steel band — resists deformation and ensures lasting clamp integrity
Rounded edges — protect hose surfaces from damage during tightening
Standard drive head — fits flat screwdriver, nut driver or socket
Benefits
Reliable grip: maintains secure hold under pressure, vibration or environmental changes
Versatile fit: accommodates a range of hose diameters with one clamp
Durable design: steel construction holds up in demanding use cases
Safe on hoses: rounded edges reduce the chance of hose gouging or wear
Safety
Wear eye protection — metal shavings or burrs may dislodge during fitting or removal
Avoid over-tightening — excessive torque may deform the hose or strip clamp threads
Ensure clamp is evenly seated around hose — misalignment may lead to leaks or failure
Re-check clamp tightness periodically, especially in conditions involving vibration, temperature fluctuations or pressure cycling
