Trident Marine 316 SS Non-Perforated Worm Gear Hose Clamp - 15/32" Band - (1-1/4" – 1-3/4") Clamping Range - 10-Pack - SAE Size 20

The Trident Marine 316 SS Non-Perforated Worm Gear Hose Clamp in SAE Size 20 is engineered for serious boaters and marine technicians who demand reliability where saltwater corrosion is a constant threat. This 10-pack of stainless steel clamps secures fuel lines, coolant hoses, and intake manifold connections across a 1-1/4" to 1-3/4" clamping range, making them essential for engine maintenance, winterization, and repair work on freshwater and saltwater vessels alike. Whether you're rebuilding a cooling system or replacing deteriorated hose connections, non-perforated clamps provide uniform pressure distribution without the weak points that perforation creates.

Manufactured from AISI 316 stainless steel with high tensile strength, these worm gear clamps resist rust, pitting, and galvanic corrosion that plague standard carbon steel fasteners in marine environments. The 15/32" band width distributes clamping force across a wider surface area, reducing hose deformation and extending service life on both rigid and flexible fuel and coolant lines. The non-perforated construction eliminates stress concentration points, critical when exposed to temperature cycling, vibration, and the constant expansion-contraction cycle of engine operation at sea.

These clamps are ideal for inboard engines, outboards with aftermarket cooling upgrades, and any marine application requiring 316-grade corrosion resistance and durable all-stainless construction. The SAE Size 20 specification fits standard hose barb fittings found on most marine engines and aftermarket cooling components. Stock a 10-pack in your engine room locker—non-perforated stainless clamps are insurance against mid-season hose failure and the costly repairs that follow.
