Copper Straight Hose Connector Double-Sided Female Thread

Match the connector size to your hose's inner diameter. For example, a 6mm connector fits a hose with a 6mm (approximately 1/4") inner bore. For reducer variants (e.g., 8mm to 6mm), the larger number is the inlet and the smaller is the outlet. When in doubt, measure your hose ID with calipers before ordering.

Brass and copper fittings of this type are generally rated for low-to-medium pressure applications. They are typically suitable for fuel lines, coolant lines, and water systems operating at pressures generally found in small engines and DIY plumbing. For high-pressure hydraulic systems, please contact us to confirm suitability.

Brass fittings offer good corrosion resistance and are generally suitable for outdoor and moist environments. Copper variants also resist corrosion well. However, prolonged exposure to saltwater or highly acidic fluids may reduce service life. Applying thread sealant tape is recommended for outdoor installations.

Yes. These connectors are sized in metric (mm) and are designed to fit standard metric hoses. Available sizes range from 4mm to 25mm. The double-sided female thread design allows secure barb-to-barb or thread-to-barb connections depending on your application.

The Brass variants are made entirely of brass, offering consistent material properties. The Mixing variants typically combine brass body construction with copper or other compatible alloy components, which may suit specific fluid compatibility requirements. Check the variant label for details.

For threaded connections, applying PTFE thread seal tape (plumber's tape) is generally recommended to ensure a leak-free seal, especially in fuel or water line applications. Hose barb ends should be secured with an appropriate hose clamp for best results.

These brass and copper connectors are generally compatible with gasoline, diesel, water, coolant, and light oils. They are not recommended for use with strong acids, alkalis, or aggressive solvents. If you are unsure about fluid compatibility, please contact us before purchasing.
