Parker 222P-6-2 Pipe Adapter Mnptf X Fnptf Brass 1000 Psi

Product Description

The PARKER 222P-6-2 is a brass pipe adapter designed to connect a 1/8 inch male NPT fitting (MNPTF) to a 3/8 inch female NPT fitting (FNPTF). It serves as a reducer adapter in compressed air, hydraulic, and fluid-transfer lines where thread sizes need to step up or step down between components. Rated to 1000 psi maximum working pressure and a temperature range of -65 degrees F to 250 degrees F, this adapter suits demanding industrial and mechanical service environments. Licensed trades including pipefitters, plumbers, and HVAC technicians commonly use fittings in this series during equipment installation, repair, and system fabrication.

This adapter is appropriate for use in compressed air systems, hydraulic lines, pneumatic control circuits, and general-purpose fluid piping where a transition between 1/8 inch and 3/8 inch NPT threaded connections is required. Its brass construction provides good resistance to corrosion in water, oil, and air service. The MNPTF x FNPTF configuration allows direct thread engagement without additional adapters, making it a straightforward solution in tight-space installations or panel-mount assemblies.

Key Features

• Steps a 1/8 inch male NPT thread up to a 3/8 inch female NPT thread in a single fitting
• 1000 psi maximum working pressure rating for high-pressure fluid and air service
• Brass construction provides corrosion resistance in water, oil, and compressed air applications
• Operating temperature range of -65 degrees F to 250 degrees F covers most industrial service conditions
• Meets SAE J530 and SAE J531 standards for pipe threads and fittings
• Compact form factor suitable for use in panel assemblies and confined installations

Compatibility

Designed as an OEM-style replacement or service fitting for industrial fluid and pneumatic systems requiring a MNPTF x FNPTF reducer adapter with 1/8 inch male and 3/8 inch female NPT threads.

Installation Notes

Installation should be performed by a qualified pipefitter, plumber, or HVAC technician in accordance with applicable codes. Depressurize and isolate the system completely before removing or installing any threaded fittings. Apply an appropriate thread sealant or PTFE tape to the male threads per system requirements and manufacturer guidelines. Do not overtighten brass fittings, as excessive torque can crack or deform the fitting body.
