When standard clamps fail, RockClamp’s heavy duty hose clamps deliver the extreme clamping force and durability required for high-pressure environments. As a specialist heavy duty hose clamp manufacturer, we provide robust solutions engineered for thick-walled reinforced hoses used in turbochargers, heavy-duty truck cooling systems, and industrial fluid transport. Designed to withstand extreme vibration and thermal cycles, our clamps ensure a permanent, leak-proof seal under the most demanding conditions.
Description:
This heavy-duty stainless steel clamp features two reverse-oriented hex socket bolts that engage with an internal solid threaded shaft, enabling synchronized tightening for uniform radial compression and secure hose retention. Designed for demanding industrial applications, the 1.0mm thick stainless steel band is available in both 20mm and 24mm widths, offering exceptional corrosion resistance combined with high load-bearing capacity. The dual-bolt configuration ensures vibration-resistant performance, making it particularly suitable for high-pressure hydraulic systems and automotive exhaust applications where reliable, long-term sealing is critical.

At RockClamp, we don't just make clamps; we engineer security for your most critical connections. Our heavy-duty range is built to exceed industry standards for torque and tensile strength.
High Torque Performance: Featuring a reinforced bolt and solid trunnion design, our T-bolt heavy duty clamps allow for high tightening torques without deforming the band.
360° Uniform Sealing: The bridge-style design prevents hose extrusion and ensures even pressure distribution around the entire circumference.
Corrosion Resistance: Available in W4 (SS304) and W5 (SS316) grades, our clamps are suitable for marine, chemical, and offshore applications where saltwater and acids are present.
Smooth Inner Band: Specially deburred edges and a smooth inner surface protect expensive hoses from cuts or abrasion during high-pressure expansion.
Heavy Trucks & Buses: Intercooler (CAC) systems, radiator hoses, and exhaust systems.
Industrial Machinery: Hydraulic systems, irrigation pumps, and large-scale air filtration.
Marine & Offshore: Engine cooling, fuel delivery, and water treatment systems.

Q: What makes a clamp "heavy duty" compared to standard worm gear clamps?
A: Heavy duty clamps, particularly T-bolt styles, have a much higher band tension and can withstand significantly higher pressure and vibration. They use a thicker band and a high-strength bolt rather than a perforated worm drive.
Q: Which material grade should I choose for marine environments?
A: For maximum longevity in saltwater, we recommend our SS316 (W5) heavy duty clamps, which offer superior pitting resistance compared to SS304.
Q: Can you provide customized sizes for oversized industrial pipes?
A: Yes. As a heavy duty hose clamp manufacturer, we can customize band widths and diameters to meet specific engineering requirements for large-scale infrastructure projects.
