Brass Needle Valves

Shop brass needle valves for precise manual flow regulation in hydraulic, pneumatic, instrumentation and industrial fluid systems. Our selection includes brass needle valves from Tompkins and Midland Industries in straight, angle, compression, pipe-thread, union and SAE 45° flare configurations. ## Brass Needle Valves for Precise Flow Control Brass needle valves use a finely threaded stem and tapered needle to provide gradual, controlled adjustment of fluid or air flow. Unlike ball valves designed primarily for quick on/off operation, a needle valve allows smaller changes in flow, making it well suited for applications where accurate manual regulation is important. These valves are commonly used in hydraulic and pneumatic systems, instrumentation lines, industrial equipment, testing systems and other applications requiring controlled flow. ## Brass Needle Valve Configurations Our brass needle valve selection includes multiple connection and body configurations to match different piping and tubing requirements. Available styles include: * Straight brass needle valves * 90-degree angle needle valves * Compression-to-pipe needle valves * Compression union needle valves * Pipe union needle valves * Pipe-to-pipe needle valves * SAE 45° flare needle valves * Bibb and specialty needle valves Choosing the correct configuration can simplify installation while providing the precise flow adjustment your system requires. ## Compression, Pipe and SAE 45° Needle Valves Connection type is one of the most important considerations when selecting a needle valve. Compression needle valves connect directly to compatible tubing and are commonly used where compact, serviceable connections are needed. Pipe-thread needle valves are available in several straight and union configurations for threaded piping systems. SAE 45° flare needle valves provide controlled flow in systems using compatible flare fittings and tubing. Always confirm the connection style, nominal size and mating components before ordering. ## Choosing the Right Brass Needle Valve Before selecting a brass needle valve, verify: * Port or tubing size * Connection and thread type * Straight or angle configuration * Maximum operating pressure * Operating temperature * Required flow range * Fluid or gas compatibility * Installation orientation and available space Because pressure ratings and operating specifications vary by valve series and size, always review the individual product specifications before installation. ## Brass Needle Valves for Hydraulic and Industrial Applications Brass needle valves are commonly used where controlled manual flow adjustment is required in hydraulic equipment, pneumatic systems, instrumentation, industrial machinery and fluid-handling applications.
