1/8 MPT Pipe Nipple

The 1/8 MPT Pipe Nipple by FRAGOLA is a precision straight adapter fitting designed to connect two 1/8-inch NPT male threads in fluid and pneumatic systems. This compact connector serves as an essential component in hydraulic lines, fuel systems, air brake circuits, and industrial applications where reliable port-to-port connections are critical. Technicians, mechanics, and system integrators rely on these nipples to eliminate leaks and maintain system integrity in demanding environments.

Constructed from lightweight aluminum with blue anodized finish, this fitting delivers corrosion resistance and durability while remaining economical for high-volume installations. The NPT (National Pipe Thread) male-to-male configuration ensures proper tapered thread engagement on both ends, creating a secure seal without additional sealant tape in most applications. The anodized surface not only protects against oxidation but also provides visual identification and enhanced aesthetics in visible system layouts. At just 0.01 lbs, the nipple minimizes weight impact in mobile and aerospace applications while maintaining full structural integrity.

This 1/8 MPT Pipe Nipple is ideal for technicians upgrading or maintaining hydraulic systems, custom fuel injection setups, pneumatic tool lines, and OEM equipment requiring compact straight adapters. The straight design eliminates elbows and reduces overall footprint in tight engine compartments or enclosed cabinets. Compatibility extends across any system using 1/8-inch NPT ports—from automotive and marine to industrial machinery and agricultural equipment. Installation is straightforward: hand-thread or use a wrench on the fitting body for torque application, ensuring proper alignment before final tightening.
