Shields Hose Hose Clamps

Shields Hose Clamps: Built for the Demands of the Marine Environment

When it comes to securing marine hose connections aboard yachts and pleasure craft, the clamp is every bit as important as the hose itself. Shields Hose, a brand under the SeaStar Solutions family, has long been the go-to name for complete marine fluid-system solutions — and their hose clamps are engineered specifically to complement and secure their own industry-leading hose lines.

Shields Hose specializes in tubing and related fittings, with products designed mainly for yachts and pleasure craft that meet the requirements set by USCG, ABYC, and other regulatory agencies. That same commitment to standards compliance extends directly to their clamp lineup.

The 720 Series: T-Bolt Clamps for High-Demand Exhaust Applications

Shields' 720 Series consists of T-bolt exhaust hose clamps constructed from 316 stainless steel. These marine-grade 316 stainless steel T-bolt band clamps are designed specifically for Shields 200 and 250 Series marine exhaust hose. The T-bolt design delivers uniform 360-degree clamping force — critical on wet-exhaust systems where vibration, heat cycling, and constant moisture exposure can work conventional worm-gear clamps loose over time.

These exhaust hose clamps are designed to fit Shields Series 200, 201, 210, 250, and 252 hoses, and are well suited for applications below the waterline. Beginning with 4-1/2", clamps are also available for Shields 202 Series hoses, designated by the suffix "S." Size options span a wide range of nominal inside diameters, making it straightforward to match the correct clamp to the correct hose series.

710 Series: Marine-Grade Worm Gear Clamps

For general-purpose marine plumbing — water supply, sanitation, bilge, and cooling lines — Shields offers the 710 Series worm gear clamps. All components are manufactured from marine-grade 316 stainless steel to resist corrosion, providing the strength needed for clamping hoses, wires, cords, and many other applications. The 316 alloy is the correct choice for saltwater environments: 316 stainless resists chloride pitting better than 304 due to its added molybdenum content — a smart choice for seawater exposure.

Why Choose Shields Clamps Over Generic Alternatives?

Generic hardware-store clamps are often made with 304 stainless or even zinc-plated mild steel — materials that can corrode rapidly in the bilge or near salt spray. Unlike general-purpose clamps, marine-grade hose clamps are engineered for saltwater and high-vibration environments. Shields clamps are purpose-built to work in concert with Shields hose series, meaning the clamp diameter ranges are sized to seat correctly on the hose's outer diameter without over- or under-clamping.

Shields Marine offers a comprehensive line of marine-grade products engineered to meet or exceed strict ABYC, NMMA, and USCG standards, providing the durability required for complex onboard plumbing. Choosing Shields clamps alongside Shields hose ensures every connection in your vessel's fluid system speaks the same engineering language — a detail that matters when a fitting failure below the waterline is not an option.

Selecting the Right Shields Hose Clamp

• T-Bolt (720 Series): Best for wet-exhaust and high-vibration connections; pairs directly with Shields 200, 201, 210, 250, and 252 Series exhaust hose.
• Worm Gear (710 Series): Ideal for water supply, sanitation, cooling, and general-service applications; available across a wide SAE size range.
• Material: All Shields clamps use 316 stainless steel throughout — band, housing, and screw — eliminating the weak-link problem of mixed-metal clamps.
• Sizing: Match clamp diameter to the hose's outside diameter when seated on the fitting, centering the clamp's adjustment range for best sealing performance.
