1/4in NPT Male Pipe Union Black

The 1/4in NPT Male Pipe Union Black from REDHORSE PERFORMANCE is a critical fluid-transfer fitting designed for high-performance automotive plumbing systems. Whether you're building a custom fuel system, upgrading your cooling circuit, or routing hydraulic lines for a competition vehicle, this male union connector provides the reliable, leak-free connections that separates amateur builds from professional installations. NPT (National Pipe Thread) fittings are the industry standard for pressurized automotive applications, offering tapered threads that create a mechanical seal without additional sealant tape in most performance scenarios.

This union features a full 1/4-inch NPT male connection, allowing you to join two hose lines, adapters, or block ports with a single, compact fitting that minimizes dead space in tight engine bays. The black finish not only resists corrosion and oxidation but also maintains a professional appearance in custom builds where aesthetics matter as much as function. REDHORSE PERFORMANCE fittings are precision-engineered from quality materials and tested for vibration resistance, temperature cycling, and pressure stability—critical performance attributes when fuel, coolant, or brake fluid is flowing at high flow rates through your system.

Mechanics and fabricators trust REDHORSE fittings for street and race engine builds alike, from turbocharged four-cylinders to big-block V8 swaps. This 1/4in NPT Male Pipe Union works seamlessly with fuel rails, oil coolers, transmission coolers, and custom radiator circuits, making it an essential component for any serious modification project. Its compact 2.8 x 1.15 x 3.8-inch footprint and light 0.045-pound weight mean it won't add bulk or weight to your installation, while its universal NPT thread standard ensures compatibility across brands and system configurations.
