NPT Reducer 3/8-1/8

The NPT Reducer 3/8-1/8 is a precision hydraulic and pneumatic adapter designed for builders and mechanics who require exact port matching in various applications. This reducer steps down from a 3/8-inch NPT inlet to a 1/8-inch NPT outlet, addressing common compatibility issues in fuel systems, brake lines, and coolant circuits without the need for custom fabrication.

This fitting features standard NPT (National Pipe Thread) tapered threads that ensure a reliable, leak-free seal. It is compact and lightweight, making it ideal for installation in tight spaces, while minimizing pressure drop and maintaining full flow capacity for low-restriction applications.

The NPT Reducer is beneficial for frame-off restorations, LS and big-block swaps, and fuel system upgrades, seamlessly integrating with components that utilize 1/8-inch port connections. Its design is suitable for a range of applications, including fuel pressure regulators and coolant bypass blocks.
