Parker PT-00174 Steel Flared Tube Connector 1/4 in Od

Product Description

The PARKER PT-00174 is a steel flared tube connector designed for high-pressure hydraulic and fluid system applications. It features a 37-degree flare angle with flare-to-flare end connections and a 0.25-inch tube outside diameter. Rated to 7,500 psi maximum working pressure and up to 500 degrees F, this connector is built for demanding service environments. At 1.39 inches overall length, it is a compact, direct-connection fitting suitable for routing tubing in tight equipment spaces. Licensed HVAC technicians, plumbers, and fluid system mechanics install this type of fitting in both stationary and mobile hydraulic systems.

This connector is suited for use in high-pressure fluid and gas line assemblies where a 37-degree flare connection is specified. The flare-to-flare configuration allows direct tube-to-tube coupling without adapters. Typical applications include hydraulic control lines, refrigeration tubing connections, and industrial fluid transfer systems operating within the rated pressure and temperature envelope. It conforms to ISO 8434-2, SAE J514, and SAE 070121 standards, making it appropriate for systems where those specifications are required.

Key Features

• 37-degree flare angle meets ISO 8434-2 and SAE J514 standards
• Maximum working pressure of 7,500 psi for high-pressure service
• Maximum working temperature of 500 degrees F (260 degrees C)
• Flare x flare end connections for direct tube-to-tube coupling
• 0.25-inch tube OD with matching 1/4 x 1/4 thread sizing
• Steel construction for strength and durability in industrial environments

Compatibility

Designed as a standard 37-degree flare connector for use in hydraulic, refrigeration, and fluid transfer tube assemblies where ISO 8434-2 and SAE J514 flare fittings are specified.

Installation Notes

Installation should be performed by a qualified mechanic or technician familiar with high-pressure fluid systems. Depressurize and isolate the line completely before disassembling any fittings. Ensure tube ends are properly flared to the correct 37-degree angle before assembly to prevent leaks under pressure. Follow applicable system codes and manufacturer torque guidance for the host equipment when making final connections.
