304 Stainless Bent Elbow 3.500 180-Degree

The 304 Stainless Bent Elbow 3.500 180-Degree from Woolf Aircraft Products is a precision marine plumbing component engineered for serious boaters and water sports enthusiasts who demand reliability in demanding saltwater and freshwater environments. This 180-degree elbow fitting serves as a critical junction point in through-hull applications, exhaust systems, and intake manifold configurations where directional flow changes are essential. Whether you're running a center console, cabin cruiser, or commercial fishing vessel, this stainless steel elbow ensures your cooling, drainage, or ventilation systems function flawlessly across thousands of operating hours.

Constructed from 304-grade stainless steel, this bent elbow offers superior corrosion resistance compared to standard carbon steel or lower-grade stainless alloys—a critical advantage for saltwater anglers and offshore operators where galvanic corrosion can compromise fitting integrity within seasons. The 3.500-inch diameter accommodates substantial flow volumes typical of modern marine engines and auxiliary systems, while the true 180-degree bend allows complete reversal of directional flow without leakage points or turbulence zones. The precise machining and seamless construction minimize pressure drop and reduce cavitation risk in high-flow scenarios, translating to improved engine cooling efficiency and extended component lifespan.

This fitting is ideal for boat owners retrofitting aging cooling systems, replacing corroded through-hull fittings, or upgrading factory exhaust configurations to enhanced aftermarket manifolds. The 304 stainless construction handles the thermal cycling and vibration inherent to marine propulsion without stress-cracking or fatigue failure—performance-critical for vessels operating in variable sea conditions. Installation requires compatible flanges or hose barb adapters; verify your system's connection diameter and pressure rating before ordering to ensure seamless integration with existing plumbing architecture.
