Brass Fittings for Marine Pitot Tube Systems
When it comes to keeping your boat's speedometer reading accurately, every connection in the pitot tube system matters. Brass Fittings brings its precision-hardware expertise directly to the Pitot Tubes & Accessories category, offering purpose-built couplings designed to create leak-free, reliable links within marine speed-sensing assemblies.
What Is a Pitot Tube and Why Do the Fittings Matter?
A pitot tube — sometimes called a pitometer — is the sensing device that feeds water pressure data to a manually operated boat speedometer. It is used in a manually operated boat speedometer and runs through the hull into the water below, using two holes to measure speed. The tube itself is only part of the equation: the barb couplings and connectors that tie the tube to the speedometer hose must maintain a consistent, airtight seal at all times. Any leak or loose joint introduces pressure inconsistencies that translate directly into inaccurate readings on the gauge.
This is where material choice becomes critical. Brass is immensely strong, durable, and incredibly resistant to salt water, rust, and corrosion — exactly the properties demanded in a below-waterline or bilge-area fitting that is constantly exposed to moisture. Brass also machines to extremely tight tolerances, ensuring a snug, reliable barb-to-hose grip that plastic or aluminum alternatives simply cannot match over time.
The Brass Fittings Pitot Tube Barb Coupling
The flagship offering from Brass Fittings in this category is the Pitot Tube Barb Coupling (Part No. 33091B). Sized at 1/8" and finished in black, this barb coupling is purpose-built for pitot tube connections in marine environments. Its compact barbed design locks securely onto pitot hose lines, resisting pull-out forces even in high-vibration powerboat applications. The 1/8" sizing is a widely adopted standard in marine speedometer plumbing, making this coupling a compatible drop-in solution for many existing boat installations.
Where Brass Fittings Fits in the Pitot Ecosystem
A complete pitot speedometer system typically involves a pickup tube, a length of flexible hose, and the critical connection hardware that ties it all together. A complete speedometer pick-up kit includes a pitot tube and mount as well as the necessary fittings to connect the speedometer hose to the speedometer. Brass Fittings focuses on that last, often-overlooked piece — the coupling — ensuring the whole chain is only as weak as its strongest link. Whether you are replacing a corroded coupling on an older vessel or completing a new build, having a properly rated brass barb fitting ensures long-term system integrity.
