Sierra 18-8055 Brass Hose Barb, Male

Upgrade your marine engine setup with a reliable brass hose barb that stands up to the toughest saltwater environments. Crafted from high-quality brass, this male hose barb delivers a secure, leak-proof connection for fuel lines, coolant hoses, and water circulation systems. Its precision-machined design ensures a snug fit without compromising flow rates, helping you maintain peak engine performance on every outing.

What sets this fitting apart is its exceptional corrosion resistance. Brass naturally forms a protective patina that fights off the relentless assault from marine moisture and chemicals, extending the life of your plumbing far beyond cheaper alternatives. Boaters and mechanics alike trust it for quick repairs or custom builds where durability meets dependability.

Key Features and Benefits

• Superior Material Strength: Solid brass construction resists galvanic corrosion, ideal for bilge pumps, exhaust systems, and raw water intakes.
• Easy Installation: Barb design grips hoses firmly with a 360-degree bite, eliminating the need for clamps in low-pressure applications or pairing perfectly with them for high-demand setups.
• Versatile Sizing: Matches standard marine hose diameters, sliding effortlessly into 5/8-inch or similar ID hoses common in outboard and inboard engines.
• Precision Threads: Male NPT threading provides a gas-tight seal when mated with female ports, reducing vibration-induced failures over long hauls.
• Maintenance-Free Reliability: No need for frequent replacements—polish occasionally to keep that mirror-like finish and optimal performance.

Pro Tips for Optimal Use

Before installing, inspect your hose ends for cracks or swelling—old hoses can sabotage even the best fittings. Heat the hose slightly with a heat gun for easier insertion, then secure with marine-grade stainless clamps for peace of mind. In high-vibration areas like engine mounts, add a loop of hose to absorb movement and prevent fatigue cracks.

For troubleshooting common issues: If you notice weeping at the joint, check for over-tightening, which can distort the barb. A light lubricant like silicone grease on the barb eases assembly without reducing grip. Regular visual checks during pre-launch routines catch wear early, keeping your vessel ready for adventure.

Why Brass Hose Barbs Excel in Marine Applications

Unlike plastic fittings that brittle under UV exposure or aluminum ones prone to electrolysis, brass strikes the perfect balance of strength, conductivity, and affordability. It's the go-to for professionals rebuilding Mercury, Yamaha, or Evinrude systems, where every connection counts toward safety and efficiency. This fitting isn't just a part—it's insurance against downtime on the water.
