The hot sell different type brass internal hexagon straight male nipple fittings are high-performance connectors engineered for seamless and secure pipe connections across pneumatic, hydraulic, and water systems. Crafted from premium CuZn39Pb3 brass—compliant with RoHS and REACH standards—these fittings combine durability with versatility, making them a top choice for both industrial and residential applications.
Featuring a unique internal hexagon drive, they eliminate the need for bulky wrenches, allowing easy installation in tight spaces using a simple hex key. Available in a range of thread types (NPT, BSP, metric) and sizes (1/8" to 1"), these nipples cater to global pipe standards, ensuring compatibility with systems worldwide. Whether for air compressors, water filters, or industrial machinery, their corrosion-resistant design—enhanced by an optional nickel plating (5μm thickness)—guarantees long-term reliability even in harsh environments.

The recessed hex socket (sizes 4mm to 12mm) enables precise tightening with a hex key, offering better torque control than traditional hexagonal nuts. This design is ideal for confined spaces where wrenches can’t reach, minimizing the risk of rounded corners during installation and reducing setup time significantly.
With NPT (tapered), BSPP (parallel), and metric threads (M10x1 to M24x1.5), these fittings align with international pipe standards. Each nipple is clearly marked with thread type and size, simplifying identification and ensuring a perfect fit for systems in North America, Europe, and beyond.
Made from CuZn39Pb3 brass, the fittings resist corrosion in water, air, and non-corrosive fluids. For humid or salty environments—such as coastal areas or industrial facilities—the optional nickel plating adds an extra protective layer, extending service life and maintaining performance.
Their straight cylindrical shape fits into tight spaces, while the lightweight build (e.g., 50g for 1/4" NPT) reduces strain on flexible hoses and connectors. This makes them suitable for applications where space and weight are critical, such as air compressors and portable machinery.
Rated for working pressures up to 20 bar (290 PSI) (NPT/BSP) and 16 bar (232 PSI) (metric), these nipples handle low-to-medium pressure systems with ease, making them versatile for both professional and DIY projects.
Ideal for connecting air hoses to compressors, valves, and tools in automotive workshops, woodworking facilities, and industrial automation lines. Their secure seal prevents air leaks, ensuring consistent performance in pneumatic tools and machinery.
Perfect for low-pressure hydraulic circuits, such as lubrication systems and coolant pumps, where space is limited. The internal hex design simplifies installation in tight engine compartments or machinery housings.
Used to connect filters, pressure gauges, and shut-off valves in residential and commercial water systems. The corrosion-resistant brass and optional nickel plating make them safe for potable water applications.
A favorite among model builders, RC enthusiasts, and home brewers, these fittings allow customization of fluid lines in compact setups. Their easy installation and compatibility with various pipe sizes make them accessible for non-professional users.
Whether for industrial machinery or home projects, the hot sell different type brass internal hexagon straight male nipple fittings deliver reliability, versatility, and ease of use—making them a must-have for any pipe connection need.
