4PCS Solid Brass 1/4' Inline Air Pressure Regulators Key benefits Precise pressure control: Inline regulator with a smoothturning adjustment knob lets you set and maintain stable air pressure for consistent tool performance. Reliable construction: Solid brass body resists degradation and wear, built for long service in workshop and industrial settings. Easy integration: 1/4' female and male NPT threads provide direct compatibility with standard 1/4' air hose systems and common pneumatic fittings. Flexible installation: Supports bidirectional installation so you can place the regulator where it fits your air line layout. Compact and servicefriendly: Small footprint simplifies placement, helps prevent pressure fluctuations, and makes routine maintenance easier. Product features Quantity: 4PCS inline air pressure regulators. Threads: 1/4' female and male NPT. Compatibility: Designed for most 1/4' air hose systems and pneumatic equipment, suitable for air compressors and air tools that require controlled inlet pressure. Construction: Solid brass body and components for corrosion resistance and durability. Adjustment: Smoothturning knob for realtime pressure adjustment and fine control of airflow. Dimensions: Each unit measures approximately 15/8' in length with a 1/2' diameter body. How it solves problems Eliminates tool performance inconsistency caused by pressure spikes or drops by providing steady, adjustable inlet pressure. Reduces wear on sensitive pneumatic tools by preventing overpressure and smoothing airflow. Simplifies system setup and maintenance by using standard 1/4' NPT connections and a compact inline design. Typical applications Workshop and garage: Regulate pressure for impact wrenches, air ratchets, and pneumatic drills to maintain consistent torque and finish. Painting and finishing: Stabilize pressure for spray guns to prevent uneven spray patterns and runs. Industrial maintenance and production: Control feed pressure to pneumatic assemblies, testing rigs, or airoperated fixtures where precise pressure matters. Installation and use notes Install inline with the airflow direction that suits your layout; bidirectional mounting is supported. Use with standard 1/4' NPT hoses and fittings for a straightforward connection. Adjust the knob while monitoring downstream pressure or tool performance to set the pressure for each application. Includes Four (4) solid brass inline air pressure regulators, each approx. 15/8' long, 1/2' diameter body, with 1/4' male and female NPT threads. Materials and compatibility summary Material: Solid brass Thread size: 1/4' NPT (male and female) Compatible with: Most 1/4' air hose systems and common pneumatic equipment This product provides compact, durable, and precise inline pressure regulation for air tools and pneumatic systems requiring stable inlet pressure.
