In marine engineering, reliability is essential; it is not optional. Every component, from the bilge to the flybridge, including clamps, fittings, and seals, plays a crucial role in ensuring yachts remain operational and safe. A failure of even a single component at sea can lead to costly downtime or jeopardise crew safety.
Marine engineers, yacht builders, and solo ocean racers, including Sunseeker, Princess Yachts, Oyster Yachts, and Pip Hare, trust JCS Hi-Torque Hose Clamps. With Lloyd’s Register Type Approval, corrosion-resistant 316 stainless steel, and over 250 years of British manufacturing expertise, JCS hose clamps are designed for optimal performance under pressure.
PROVEN IN THE WORLD’S TOUGHEST RACE: PIP HARE OCEAN RACING
In 2019, world record-breaking British sailor Pip Hare experienced a race-ending mechanical failure during her first solo IMOCA qualifier, which was a 2,000-mile test from Brittany to Brest. A crucial gooseneck pin on her yacht’s mast had worked loose. With no permanent fix available, Pip used a JCS Hi-Torque hose clamp to secure the pin, allowing her to continue the race.
This quick repair proved effective for the remainder of her journey, showcasing the strength and precision engineering of JCS clamps. As Pip advances in her elite sailing career, she continues to rely on JCS Hi-Torque clamps to secure fuel, hydraulic, and cooling system components that must perform flawlessly in the most extreme marine conditions.
“When you’re alone on deck in heavy weather, knowing I have JCS Hi-Torque hose clamps on board gives me total confidence that my systems will hold, even in the harshest conditions.” — Pip Hare, Ocean Racing
THE RIGHT MATERIAL: 316 STAINLESS STEEL FOR TRUE MARINE-GRADE DURABILITY
Salt spray, condensation, and vibration are constant enemies in marine systems. Zinc-coated clamps can quickly corrode, seize, or fail to function correctly. JCS Hi-Torque and Hi-Grip clamps are made from marine-grade 316 stainless steel, incorporating molybdenum for enhanced resistance against pitting corrosion, the most significant threat in saltwater environments. Each clamp is salt-spray tested and Lloyd’s Register Type Approved, ensuring it maintains tensile strength and sealing integrity in extreme conditions, from tropical humidity to sub-zero temperatures.
PRECISION TORQUE AND A TRUE 360° SEAL
Traditional nut-and-bolt or budget worm-drive clamps apply pressure unevenly, leaving weak spots and risking leaks under vibration. JCS Hi-Torque clamps are different. Their cold-forged bands and pressed-in threads deliver a uniform 360° seal, maintaining consistent clamping force even on reinforced hoses and irregular surfaces.
As Colin Plumb, JCS Technical Specialist, explains: “The geometry of a Hi-Torque clamp ensures even compression all the way around the hose. That’s why they perform so well under vibration — they don’t loosen or distort like traditional clamps.”
This even pressure makes Hi-Torque clamps ideal for marine exhaust systems, cooling circuits, and bilge pumps, where reliability under vibration is non-negotiable.
INSTALLATION THAT SAVES TIME AND PREVENTS DAMAGE
Marine maintenance often happens under pressure in tight engine bays or during demanding voyages. Ease of installation is required! JCS Hi-Torque Hose Clamps feature a smooth worm-drive design that allows fast, tool-friendly adjustment without compromising on torque control. For best results:
Always position the clamp centrally over the hose barb.
Tighten incrementally to the recommended torque — over-tightening can damage hoses.
Recheck after use in high-vibration applications to maintain seal integrity.
For emergency repairs, JCS offers the Multi-Torque adjustable banding system, allowing engineers to create a custom clamp of any diameter directly from a kit, a game-changer for ocean racing and offshore repair crews.
RELIABILITY THAT’S ENGINEERED, TESTED, AND PROVEN
Every JCS clamp is designed, manufactured, and tested in-house at our headquarters in Sudbury, Suffolk. This complete production control ensures full batch traceability, precision machining, and consistent quality across every unit.
With ISO 9001:2015 certification, Lloyd’s Register, and BSI Kitemark approvals, JCS clamps meet and often exceed the most stringent international standards. Used by the RNLI, Sunseeker, and Pip Hare Ocean Racing, JCS clamps are proven to withstand marine corrosion, vibration, and high torque demands, making them a preferred choice across marine, offshore, and shipyard applications.
SUSTAINABLE MANUFACTURING FOR A CLEANER FUTURE
Behind the clamps is a sustainable story. JCS’s Sudbury facility is powered by a 700kW solar park and 500kWh battery system, generating clean electricity that powers production and exports surplus energy back to the UK grid. This commitment to eco-powered manufacturing and waste reduction ensures that every clamp made by JCS not only performs better but is also made responsibly.
