This male tank outlet connector is designed to replace OEM part number 16977-ZV5-900, ensuring direct compatibility for a seamless upgrade or replacement.

One of the most critical specifications is its size: 1/4 inch NPT (National Pipe Taper). This thread standard is crucial for ensuring a tight seal when connected to a corresponding female fitting. Furthermore, the construction utilizes high-quality, marine-grade material, which is paramount for resisting corrosion and degradation commonly found in saltwater environments. The precision construction is a key selling point, implying that each unit is manufactured to exacting standards for optimal performance and reliability.

The 1/4 inch NPT sizing is essential for anyone working on marine fuel systems. This specific thread size is common for fuel tank outlets and ensures that the connector will properly mate with standard fuel lines and fittings. The choice of marine-grade material is not an exaggeration; it means the connector is built to withstand constant exposure to moisture, salt, and UV radiation without prematurely failing.

Performance & Functionality

In its primary role, the Sierra International 1880406 Fuel Connector performs its job with remarkable effectiveness. The 1/4 inch NPT threads engage smoothly and securely, creating a leak-proof seal that is absolutely vital for any fuel system. I experienced zero fuel seepage after installation, even under varying engine loads and operational pressures.

The major strength of this fuel connector lies in its absolute reliability and the peace of mind it offers. Its precise construction ensures that it doesn’t require excessive force to tighten, minimizing the risk of overtightening and damaging the fuel tank fitting. A potential minor point for improvement, though not a fault of this specific unit, is that the NPT threads themselves require proper sealant for an absolute guarantee against leaks, especially in high-vibration applications. However, when installed correctly, its functionality is near-perfect for its intended purpose.

The performance of this connector exceeds basic expectations because of its robust build and specific design for marine use. It doesn’t just connect; it connects reliably.
