Reducer NPT 3/8in to 1/4in

The Reducer NPT 3/8in to 1/4in from ALLSTAR PERFORMANCE is a precision fitting designed to step down larger diameter NPT ports to smaller outlet sizes in fluid, pneumatic, and fuel system applications. This aluminum bushing reducer serves technicians, fabricators, and enthusiasts who need reliable port adaptation without compromising system integrity. Whether you're building a custom fuel delivery system, assembling pneumatic tools, or reducing line diameter in hydraulic circuits, this fitting provides the exact interface required to connect incompatible port sizes.

Manufactured from lightweight aluminum with black anodized protection, the Reducer NPT 3/8in to 1/4in features a 3/8 inch NPT male inlet and 1/4 inch NPT female outlet, enabling seamless integration into systems requiring port reduction. The anodized finish resists corrosion and oxidation, extending service life in both indoor and outdoor environments. NPT (National Pipe Taper) threading provides superior sealing without requiring additional sealant tape in most applications, though compatible thread sealant can enhance reliability in high-pressure or vibration-prone installations.

This fitting is ideal for fuel system modifications, air tool setups, and pneumatic brake line work where port size incompatibility would otherwise require custom fabrication or component replacement. The compact 2.6 x 1 x 4 inch profile fits tight engine bays and equipment enclosures without obstruction. Installers should verify thread compatibility with existing NPT components and consider thread sealant compatibility with system fluids—gasoline, diesel, air, and general hydraulic fluids are all compatible with this aluminum reducer.
