Maretron 1.5" NPT Non-Displace Hull Focus Tube

The Maretron 1.5" NPT Non-Displace Hull Focus Tube (model TFT-1.5NPT) is a precision instrument housing designed for marine survey systems and sophisticated boat navigation setups. This component serves as a dedicated mounting solution for transducers and sensing equipment on vessels where accurate water column data collection is critical. If you're running a serious fishing operation, conducting marine surveys, or managing a commercial vessel, this hull focus tube delivers the reliability and precision that professionals demand below the waterline.

Built by Maretron with marine-grade construction, the 1.5" NPT non-displacement design minimizes drag while maintaining a stable mounting platform for sensitive transducers. The NPT (National Pipe Thread) connection standard ensures compatibility with a broad range of marine plumbing and sensor integration systems. Weighing just 3 lbs and measuring 44 inches in length, this tube is engineered for flush hull installation without creating hydrodynamic disturbance—a critical advantage when running at speed or when data accuracy depends on minimal flow interference.

Boaters, charter operators, and marine technicians choose the Maretron hull focus tube for applications requiring temperature, depth, and water quality readings without sacrificing hull integrity or vessel performance. Installation is straightforward through standard 1.5" NPT ports, making retrofit projects and new-build integrations equally practical. Whether you're upgrading a legacy navigation system or building out a complete marine electronics suite, this component provides the foundation for reliable sensor deployment and long-term operational confidence on the water.
