Parker PT-00254 Brass Male Adapter 1/4 in Od 1/8-27 Nptf

Product Description

The PARKER PT-00254 is a brass flared tube male adapter designed for high-pressure hydraulic and fluid-system applications. It connects a 37-degree flared tube end to a 1/8-27 NPTF male thread, providing a leak-resistant, metal-to-metal seal. The fitting handles a maximum static working pressure of 6000 psi and a maximum dynamic working pressure of 3300 psi. Constructed from brass, it offers good corrosion resistance in compatible fluid and gas service. With a tube outside diameter of 1/4 inch and an overall length of 1.22 inches, this adapter fits into tight plumbing assemblies. It is typically installed by licensed plumbers, HVAC technicians, and hydraulic system technicians during line fabrication or repair work.

This adapter is suited for residential and light commercial fluid-system installations where a 37-degree SAE flare connection must transition to an NPTF threaded port. Common applications include refrigeration lines, hydraulic circuits, and instrumentation tubing where a reliable, high-pressure-rated male adapter is required. The flare-by-NPTF end configuration makes it a standard choice when connecting tubing assemblies to manifolds, valves, or equipment ports with tapered pipe threads. Each package contains 5 pieces.

Key Features

• 37-degree SAE flare end meets NPTF male thread in a single fitting body
• Maximum static working pressure rated at 6000 psi
• Maximum dynamic working pressure rated at 3300 psi
• Brass construction provides corrosion resistance in compatible fluid and gas service
• Meets ISO 8434-2, SAE 070102, and SAE J514 standards
• Compact overall length of 1.22 inches suits space-restricted installations

Compatibility

Designed as a standard 37-degree flare-to-NPTF male adapter for use in hydraulic, refrigeration, and instrumentation tubing systems requiring a 1/4 inch OD tube connection to a 1/8-27 NPTF threaded port.

Installation Notes

Installation should be performed by a qualified technician familiar with high-pressure fluid or refrigeration systems. De-pressurize and isolate the line fully before disassembly or fitting installation. The NPTF thread provides a dry-seal connection; inspect threads for damage before assembly and apply appropriate thread sealant only as required by the system specification. Do not over-tighten, as brass fittings can be damaged by excessive torque.
