Parker 209P-4-2 Brass Pipe Bushing 1/4 X 1/8 Mnptf Fnptf

Product Description

The PARKER 209P-4-2 is a brass pipe bushing designed to reduce a 1/4-inch male MNPTF thread down to a 1/8-inch female FNPTF thread. This fitting is used to adapt pipe or tubing connections where thread sizes differ within a pressurized system. Constructed from brass, it carries a maximum working pressure of 1000 psi and handles temperatures from -65 degrees F up to 250 degrees F. It meets SAE J530 and SAE J531 standards. Licensed plumbers, pipefitters, and HVAC technicians regularly install this type of bushing during system assembly or modification work.

This bushing fits into a wide range of industrial, commercial, and mechanical piping applications where a 1/4-inch male NPT port must be reduced to accept a 1/8-inch female NPT connection. Typical scenarios include pneumatic systems, hydraulic circuits, fuel lines, and fluid-handling assemblies that require a compact, inline thread reduction without additional fittings. Its compact form allows direct installation into tees, manifolds, valves, or other ported components.

Key Features

• Reduces 1/4-inch MNPTF male thread to 1/8-inch FNPTF female thread in a single fitting
• Rated to 1000 psi maximum working pressure
• Operating temperature range of -65 degrees F to 250 degrees F
• Brass construction resists corrosion in fluid and pneumatic service
• Meets SAE J530 and SAE J531 standards
• Compact bushing profile for direct port installation

Compatibility

Designed as an OEM-style brass pipe bushing for use in industrial, pneumatic, hydraulic, and fluid-handling piping systems that use standard MNPTF and FNPTF tapered thread connections.

Installation Notes

Installation is performed by licensed plumbers, pipefitters, or qualified HVAC technicians. Depressurize and isolate the system completely before removing or installing any pipe fittings. Apply thread sealant or PTFE tape to the male threads in accordance with the applicable system requirements and local plumbing or mechanical codes. Do not overtighten tapered NPT threads, as this can crack brass fittings or distort the sealing taper.
