Our Brass Hydraulic Bushing Adapters With Male And Female Thread are high-precision, industrial-grade fluid connection components, designed to solve thread size conversion and line connection challenges in hydraulic, pneumatic, and general industrial fluid systems. Machined from high-quality brass with strict tolerance control, these male female brass hydraulic adapters support both same-size and reducing thread configurations, delivering a reliable, leak-proof connection solution for diverse industrial piping setups. With a wide range of metric and BSP thread specifications available, our brass hex bushing reducers help operators streamline inventory management, improve assembly efficiency, and ensure long-term reliability of high-pressure fluid circuits.

These brass hydraulic thread reducer adapters adopt an optimized tapered thread connection design, which forms a rigid, vibration-resistant metal seal through the interlocking of internal and external threads. Unlike standard parallel thread fittings, this tapered structure eliminates the need for additional sealing materials in most applications, preventing fluid leakage even under high pressure and continuous vibration, which is critical for maintaining the safety and stability of hydraulic systems.
We offer an extensive selection of thread specifications for our male and female thread brass reducing nipples, including metric thread sizes from M10×1 to M24×1.5, and BSP thread sizes from G1/8 to G3/4. Both same-size and reducing thread combinations are available, allowing users to match exact piping conversion requirements, whether adapting between different thread standards or resizing line diameters in a fluid circuit. This flexibility eliminates the need for custom machining, reducing procurement lead times and costs for industrial users.
Manufactured from high-grade anti-rust brass, our brass hydraulic bushing adapters deliver excellent corrosion resistance, mechanical strength, and high temperature stability, suitable for long-term use in harsh industrial environments. The fittings are compatible with a wide range of common industrial media, including hydraulic oil, water, compressed air, and inert gases, making them a versatile solution for diverse fluid transfer applications across multiple industries.
The integrated hexagonal midsection of our brass hex hose nipple adapters is engineered for easy wrench tightening, enabling quick, secure installation into corresponding threaded ports without slippage or fitting damage. This design simplifies both initial assembly and ongoing maintenance, cutting down labor time and reducing unplanned downtime for production facilities and maintenance teams.

Our male female brass hydraulic bushing adapters are widely used across industrial sectors requiring reliable fluid line connections, including:
Hydraulic power systems and oil port connections for directional valves, elbows, and tee fittings
Pneumatic automation equipment and compressed air piping systems
Industrial fluid transfer lines for water, oil, and inert gas delivery
Mold cooling water circuit thread adaptation and piping modification
Engineering machinery, agricultural equipment, and vehicle hydraulic circuit retrofits
Chemical processing and general manufacturing plant piping systems
These adapters enhance production efficiency, improve connection reliability, and reduce maintenance costs for users including hydraulic equipment manufacturers, industrial maintenance service providers, and engineering contractors.
First, always tighten the fitting using a wrench on the hexagonal midsection only, within the recommended maximum torque range to avoid thread damage. Second, ensure use within the applicable temperature and pressure ratings. Third, select the correct thread specification to match your piping, and use compatible sealing materials if required for extreme operating conditions.
These adapters are designed for use with hydraulic oil, water, compressed air, and inert industrial gases. For use with corrosive chemicals or specialized media, please consult our engineering team for compatibility guidance prior to installation.
Yes. Our adapters feature a reinforced tapered thread design and high-strength brass construction, making them suitable for most medium and high pressure hydraulic systems commonly used in industrial and mobile equipment. Always verify pressure ratings match your application requirements before installation.
