Stainless Steel Reinforced Hose Clamps – Heavy-Duty Marine Grade (All Sizes)

These reinforced hose clamps are engineered to deliver superior strength and longevity on board boats, yachts, or in industrial applications. Constructed entirely from high-grade stainless steel, they offer outstanding resistance to rust and corrosion even with continuous exposure to saltwater, fuel, and chemicals. The heavy-duty design features an extra-wide band (21 mm for smaller sizes, 24 mm for larger sizes) that wraps around hoses securely without cutting or pinching. The band’s increased thickness (1.0–1.2 mm) provides additional rigidity and clamping force. The worm gear screw mechanism is robust and precise – it allows extremely tight clamping for a leak-proof seal, and since all parts (screw, housing, band) are stainless, the clamp won’t seize or corrode over time. This means you can tighten or loosen it even after years of service, ensuring long-term maintainability. The clamps perform reliably under high vibration and stress, common in marine environments, keeping hoses firmly in place.

Size Variants and Usage Recommendations:

• Small diameters (36–67 mm range, 21 mm band width): Best for thinner hoses such as fuel lines (e.g. 5/16" to 5/8" inner diameter hoses), small freshwater plumbing, vent hoses, and other auxiliary systems. These sizes give a secure grip on connections in small boats and engines where space is tight but maintaining a leak-free seal is critical. Use them for fuel delivery hoses, small bilge pump hoses, and tubing for marine heads or sinks.
• Large diameters (68–112 mm range, 24 mm band width): Suited for heavy-wall hoses and pipes – for example, engine coolant intake hoses, large pump discharge hoses, marine exhaust flex hoses, or high-capacity bilge hoses. These larger clamps handle substantial pressure and vibration, making them ideal for the primary systems on medium to large vessels. They excel in securing critical hoses on inboard engines and generator systems, where failure is not an option.
• Marine & industrial use: With their all-stainless, reinforced build, these clamps are not only ideal for marine use but also for any application demanding corrosion resistance – such as plumbing in coastal homes, aquaculture facilities, or food-grade processing (where stainless is required). Wherever standard galvanized clamps would rust out, these marine-grade clamps provide peace of mind and extended service life. Investing in these heavy-duty clamps means fewer replacements and a safer system overall.
