（Product Description）
Our black anodized aluminum hydraulic oil nipples and fluid connection sleeves are high-performance CNC machined components, engineered for precision fluid transfer and control in automotive, industrial hydraulic, and pneumatic systems.
Manufactured from aerospace-grade 6061 or 7075 aluminum alloy, these components undergo a rigorous hard black anodization process—creating a 50–100μm thick protective layer that delivers exceptional resistance to corrosion, abrasion, and chemical degradation. The black finish also offers excellent aesthetic appeal and UV resistance for both indoor and outdoor applications.
Designed with functional versatility in mind, each component features precision external threads for secure installation, an integrated hex flange for easy wrench operation, and custom side ports/internal bores to facilitate fluid flow, pressure relief, or sensor integration. The tight-tolerance machining ensures a leak-proof seal, even under high operating pressures (up to 20MPa for 7075 alloy variants), making them ideal for high-performance hydraulic systems, racing applications, and industrial machinery.
We offer complete customization for every aspect of these components, including thread specifications (NPT 1/8" to 1", Metric M8 to M30), port diameter, overall length, and even custom anodization colors (red, blue, clear) for branding or identification purposes. Whether you need standard hydraulic oil nipples or bespoke connection sleeves for specialized equipment, our precision manufacturing capabilities guarantee a perfect fit and reliable performance.
