Tork Craft Heavy Duty Hose Clamp — 103-127 mm (Model HC103-127)
This heavy duty worm-drive hose clamp is designed to securely fasten hoses, flexible ducting or tubing whose outer diameter falls between 103 mm and 127 mm. Its robust construction makes it suitable for industrial, plumbing, automotive and HVAC applications.
Extra Information
Best used on smooth, clean hose surfaces and mating collar or pipe surfaces.
Do not overtighten—stop when hose begins to compress slightly or when slit starts to close.
Verify that band and screw threads are free of debris before installation to avoid stripping.
Inspect after thermal cycling or vibration cycles to ensure clamp remains tight.
Pro Tip
Lubricate the screw threads before tightening to reduce galling and improve torque control.
Always position the screw head away from sharp edges or moving parts to reduce wear or snagging.
Features
Size range: 103–127 mm
Worm-drive tightening mechanism — reliable and adjustable clamping force
Heavy duty band material — increased strength and durability for demanding use
Rounded edges — reduces risk of hose damage during tightening
Standard bolt head drive — usable with screwdriver, nut driver or socket
Benefits
Strong clamp force: holds hoses tightly under pressure or vibration.
Adjustability: fits range of diameters in one clamp—versatile for mixed plumbing systems.
Durability: heavy construction resists deformation and bending under stress.
Safeguards hose material: rounded edges help avoid cutting or abrasion on the hose surface.
Safety
Wear eye protection — small metal shavings or burrs may occur during installation or removal.
Do not overtighten — excessive torque may damage hose or clamp deformation.
Ensure the clamp is seated evenly around the hose — uneven clamping can lead to leakage.
Inspect periodically, especially in vibration or thermal cycling environments, to verify retention.
