Straight Hose Connector – Male (Fuel Hose Barb Fitting)
This straight hose connector (male barb) is a versatile fitting that facilitates various onboard connections. On one end, it features a male pipe thread (BSP) that screws into a corresponding female opening – for example, on a fuel/water tank, pump housing, or through-hull valve. The other end has a smooth hose barb onto which a rubber or PVC hose is secured. The straight design allows unobstructed flow of fluids and is ideal for in-line connections without bends.
The connector comes in five standard sizes – from ½″ up to 1½″ thread – covering the most common hose and pipe diameters used on boats. For instance, the ½″ threaded variant fits hose with ~13 mm internal diameter, while the largest 1½″ size accommodates hoses around 38 mm ID. This range lets you select the exact size needed for your system, whether it’s a small fuel hose on a powerboat or a large diameter bilge drain on a sailing yacht.
Made from high-grade polypropylene, the straight barb is built to withstand the marine environment. The material is resistant to fuels (gasoline, diesel), oils, and chemicals, making it safe for use in fuel lines. It also stands up to saltwater and UV exposure, so you can install it in an engine compartment or exposed deck areas without worrying about rapid degradation or corrosion. Unlike metal fittings, the plastic connector won’t rust or seize in place over time, making future disassembly easier.
Installation is straightforward: apply a suitable thread sealant or Teflon tape to the male threads, screw the connector firmly into the female port, then push your hose all the way onto the barb. The ribbed profile of the hose tail provides good grip against the hose’s interior, reducing the chance of slippage or leaks. It’s recommended to secure the connection with a hose clamp, especially for pressurized lines. After setup, test the system for leaks by running fluid through it. With this robust male connector in place, you’ll have the reliable link you need for safe operation of your vessel’s fuel, water, and drainage systems.
