3/8in NPT Male Pipe Union Clear

The 3/8in NPT Male Pipe Union Clear from REDHORSE PERFORMANCE is a precision straight adapter fitting designed for fluid and pneumatic systems requiring reliable, leak-free connections. This union-style adapter is engineered for technicians, mechanics, and system builders who need to join or repair NPT (National Pipe Thread) lines in hydraulic, fuel, coolant, or compressed air applications. The union configuration allows for tool-free disconnection and reconnection, making maintenance and serviceability straightforward without system draining.

Constructed from aerospace-grade aluminum with clear anodized finish, this 3/8in NPT Male to 3/8in NPT Male fitting delivers corrosion resistance and long-term durability in demanding environments. The clear anodizing preserves the natural aluminum appearance while providing a protective oxide layer against oxidation and wear. The straight design eliminates flow restrictions and turbulence, ensuring efficient media transfer at rated pressures. Weighing just 0.06 lbs, the compact form factor (2.85 x 1.15 x 3.8 inches) integrates seamlessly into tight engine bays, custom plumbing layouts, and modular hydraulic systems without adding bulk or complexity.

This union adapter is ideal for hot rod builders, custom automotive fabricators, industrial maintenance teams, and OEM system integrators working with 3/8in NPT ports. The straight configuration is compatible with any component featuring standard 3/8in NPT male ports—including fuel rails, pressure gauges, manifold blocks, and filter housings. Installation requires only hand-tightening at the union nut; no special tools or sealants are needed for a secure connection. The union design enables quick swaps during system testing, upgrades, or repairs, making it an essential component in any well-equipped technical shop.
