HD hose clamps
Stainless steel HD hose clamps: Absolute pressure-tight sealing for charge air piping in motorsport
Anyone working with extreme boost pressures in the high-performance and motorsport sector knows the problem: enormous forces arise in the charge air piping under full load. Conventional standard clamps quickly reach their limits here – the result is slipping silicone hoses and sudden boost pressure loss (boost leaks). Our HD hose clamps (Heavy Duty) made of high-strength stainless steel are the ultimate professional solution for sealing silicone hose connections absolutely securely and pressure-tight even under extreme pressures.
At Turbo-Parts.de you will find a large selection of reinforced high-performance hose clamps specially developed for the tough requirements of turbocharged and supercharged engines.
What makes HD hose clamps so superior?
Unlike classic hardware-store worm-drive clamps, our HD stainless steel clamps (often also referred to as hinged bolt clamps or bolt clamps) are uncompromisingly designed for maximum tensile force:
Solid bolt construction: Instead of a simple thread, these clamps feature a robust hinged bolt with a metric screw. This allows an extremely high tightening torque to be applied without the band slipping or tearing.
Wide band with rolled edges: The wide stainless steel band distributes the clamping force absolutely evenly across the entire circumference of the silicone hose. The upward-flanged outward band edges effectively prevent the clamp from cutting into or damaging the sensitive silicone material during installation.
Smooth inner band surface: An integrated bridge ensures a gapless 360-degree enclosure. There are no weak points where air could escape under extreme pressure.
Developed for high-boost setups beyond 2 bar
Whether 1.8T, 2.0 TFSI/TSI, VR6 Turbo or extreme biturbo conversions – as soon as boost pressures beyond 1.5 or 2 bar are present, HD hose clamps are mandatory. They guarantee that the connections between turbocharger, intercooler (IC), and intake manifold remain absolutely tight even under hard load changes, strong engine vibrations, and extreme temperature fluctuations in the engine bay.
Your advantages at a glance:
Proven in motorsport: Permanently withstands the highest boost pressures – no more hoses slipping on the racetrack.
100% stainless steel quality: Housing, band, and bolt are completely rust-free and resist aggressive environmental influences, salt water, and heat.
Reusable: Thanks to the solid construction, the clamps do not wear out even after repeated opening and closing in everyday workshop use.
Large selection for all common hose diameters
We supply the heavy-duty stainless steel clamps in finely graduated clamping ranges, so you can find the exact matching size for every silicone connector – whether 51mm (2 inch), 63.5mm (2.5 inch), 76mm (3 inch) or 89mm (3.5 inch).
Note for selection: When ordering, always consider the outer diameter of the silicone hose including its wall thickness (usually 4mm to 5mm per side) in order to choose the optimal clamping range.
