#20 MP X #4 FP BUSHING

Description & Features

Constructed from straight steel, this reducer bushing transitions from a 1-1/4-11-1/2 Male NPTF thread to a 1/4-18 Female NPTF thread, making it well-suited for connecting lines of significantly different sizes within hydraulic and industrial fluid systems. Both thread ends conform to SAE J476, ensuring compatibility with standard fittings and assemblies. The #20 MP X #4 FP Bushing is rated for dynamic pressures up to 3,000 PSI, supporting demanding service conditions where a reliable threaded reduction is required.

Manufactured by Brennan Industries, this fitting carries a California Proposition 65 warning for residents of that state. Its compact straight steel body keeps installation straightforward wherever a male-to-female NPTF bushing reduction is needed in a high-pressure hydraulic circuit.
