Trident Marine 316 SS Non-Perforated Worm Gear Hose Clamp - 3/8" Band - (5/16" – 9/16") Clamping Range - 10-Pack - SAE Size 3

The Trident Marine 316 SS Non-Perforated Worm Gear Hose Clamp in SAE Size 3 is purpose-built for anglers and boaters who demand reliability in saltwater environments. With a 3/8" band width and a clamping range of 5/16" to 9/16", this 10-pack delivers the secure, corrosion-resistant fastening that keeps fuel lines, cooling hoses, and water intake connections tight through years of on-the-water duty. Whether you're running offshore, cruising inland, or performing routine maintenance on your rig, these clamps represent the marine-grade hardware that separates dependable systems from failure.

Constructed entirely from AISI 316 stainless steel, these worm gear clamps offer superior tensile strength and unmatched resistance to salt spray, chlorine, and galvanic corrosion. The non-perforated design eliminates potential leak points that can plague perforated bands, while the compact "HD NON-PERF" construction delivers maximum clamping force in a minimal footprint. The worm gear mechanism provides smooth, precise adjustment—critical when tightening hoses that feed cooling water or fuel systems where over-torquing can damage fittings and under-torquing invites catastrophic leaks.

These clamps excel on inboard and outboard engines, raw-water cooling circuits, bilge systems, and transom drain applications where standard stainless or zinc-plated clamps corrode and fail. The 10-pack format ensures you have spares for emergency repairs at the dock or mid-voyage maintenance. Installation is straightforward: position the clamp around your hose barb, thread the worm screw, and tighten with a Phillips or slotted screwdriver until snug—no specialized tools required. For any marine hose diameter within the 5/16" to 9/16" range, these Trident Marine clamps deliver the salt-proof durability that keeps your boat running safely and reliably.
