Trident Marine Hose Clamps

Trident Marine Hose Clamps: Marine-Grade Holding Power Where It Matters Most

Trident Marine has been one of the most trusted names in marine plumbing since 1985, and their hose clamps are a direct reflection of that decades-long commitment to reliability on the water. While clamps may seem like a minor detail in a boat's plumbing system, they are the last line of defense between a secure connection and a potentially dangerous leak — making the quality of the clamp just as important as the hose itself.

The #710 Series: HD Non-Perforated Worm Gear Clamps

Trident's flagship hose clamp line is the #710 Series HD Non-Perforated Worm Gear Clamp, built from premium AISI 316 high-tensile-strength stainless steel throughout. What sets these apart from standard automotive-style clamps is the band design: the 11.7 mm (0.46") wide band is non-perforated and smooth on the inside with rolled edges, a construction that eliminates hose damage while simultaneously increasing clamping force. The high-strength, compact one-piece housing — 16 mm (0.63") wide — delivers one of the highest clamping force ratings found in any worm gear style clamp on the market.

These clamps are ideally suited for sanitation lines, fuel hose connections, coolant circuits, and other critical onboard plumbing runs where a leak is not an option. Trident offers the #710 Series in a wide range of SAE sizes, making it easy to find the exact fit for any hose outside diameter.

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

For larger-diameter hoses such as wet exhaust or high-flow water lines, Trident steps up to the #720 Series T-Bolt Clamp. These clamps feature a 3/4" (19 mm) wide 316 stainless steel band that delivers uniform 360° clamping pressure — ensuring a positive, strong hose connection across the full circumference of the joint. The heavy-duty hardware includes a 1/4" 18-8 stainless steel bolt with a nylon insert lock nut, rated to 75 inch-pounds maximum torque. Trident backs the #720 Series with a 3-year warranty, underscoring their confidence in the durability of these clamps in demanding below-the-waterline and exhaust applications.

Why Marine-Specific Clamps Matter

In a salt-water environment, standard stainless steel grades are prone to crevice corrosion and pitting — failures that can go undetected until a connection fails at the worst possible moment. Trident's exclusive use of AISI 316 stainless steel across their entire clamp range offers superior resistance to chlorides and the persistent moisture that defines the marine environment. This isn't a minor spec upgrade; it's the difference between a clamp that lasts a season and one that lasts for years of offshore and coastal use.

• All-AISI 316 stainless steel construction for maximum corrosion resistance
• Non-perforated, smooth inner band on worm gear clamps protects hose integrity
• T-bolt clamps provide uniform 360° clamping for larger hose applications
• Available across a broad range of SAE sizes to suit virtually any marine hose
• 3-year warranty on #720 Series T-Bolt Clamps
