Female Union Aluminum 1/8in to 1/8in NPT

The Female Union Aluminum 1/8in to 1/8in NPT adapter by ALLSTAR PERFORMANCE is a versatile straight fitting designed for pneumatic, hydraulic, and fluid transfer systems. This connector joins two female National Pipe Taper (NPT) ports of equal size, making it essential for applications where existing male-threaded lines need to connect without requiring separate couplers. Widely used in automotive fabrication, racing fuel systems, air suspension networks, and general shop plumbing, this adapter eliminates the need for custom piping runs and simplifies component assembly.

Constructed from lightweight aluminum and finished in black anodize, the Female Union Aluminum 1/8in to 1/8in NPT fitting delivers corrosion resistance and durability in demanding environments. The black anodized coating protects against oxidation while providing a clean, professional appearance on finished systems. NPT threading ensures a reliable, tapered seal when properly torqued, preventing leaks under pressure. The straight union design allows for direct connection without directional complexity, and the compact 1/8-inch port size makes it ideal for applications requiring precision fluid control or where space is limited.

This adapter serves technicians, fabricators, and enthusiasts building or servicing fuel systems, air suspension, nitrous oxide delivery lines, and custom hydraulic circuits. Installation requires only standard wrenches or pliers to tighten both female NPT ports firmly; Teflon tape or thread sealant is recommended for maximum leak prevention. Compatible with any system using 1/8-inch NPT female connections—including fuel filters, regulators, gauges, and manifold blocks—the Female Union Aluminum 1/8in to 1/8in NPT fitting is a reliable, cost-effective solution for connecting dual female ports in a single, compact union body.
