Ancor Stainless Steel Cushion Clamp - 5/16" - 10-Pack

The Ancor Stainless Steel Cushion Clamp – 5/16" – 10-Pack is an essential fastening solution for marine plumbing, fuel lines, and wiring harnesses on boats of all sizes. After decades on the water, any serious boater knows that corrosion and vibration are constant enemies—especially in saltwater environments where standard hardware fails prematurely.

These cushion clamps address both challenges by securing hoses and cables with a resilient rubber liner that dampens movement while protecting against chafe and corrosion. Manufactured from marine-grade stainless steel, the Ancor clamp resists rust and saltwater degradation that would compromise inferior metals within months. The 5/16" sizing fits standard hose and cable diameters common in both inboard and outboard engine installations, subsurface water systems, and electrical runs below deck.

The integrated rubber cushion liner isolates vibration from the engine and hull movement, preventing the metal clamp from directly contacting hoses—a design detail that extends hose life and eliminates the squeaking and creaking that plague boats with rigid fasteners. The 10-pack quantity covers multiple systems or provides spares for seasonal maintenance without the need for repeat ordering. Whether you're running new through-hull fittings, rebuilding fuel and cooling systems, or securing wiring in the engine compartment, these cushion clamps deliver reliable long-term performance in marine environments where failure is not an option.
