Parker PT-00178 Steel Flared Tube Connector 1/2 in

Product Description

The PARKER PT-00178 is a steel flared tube connector designed for high-pressure hydraulic and fluid power tubing assemblies. It features a 37-degree flare angle with flare-by-flare end connections, accepting a 1/2-inch tube OD and a 3/8 x 1/2 thread configuration. Rated for a maximum dynamic working pressure of 6000 psi, this connector is built for demanding service environments where a leak-free, pressure-rated union between two flared tube ends is required. The all-steel construction provides durability in applications subject to vibration and pressure cycling.

This connector is used in hydraulic lines, fluid power systems, and high-pressure tubing circuits found in industrial, mobile, and commercial equipment. It is suitable for technicians and pipefitters assembling or repairing tubing runs that require a reliable 37-degree JIC-style flare connection. The flare-by-flare configuration makes it appropriate for straight union connections within a tube run.

Key Features

• 37-degree flare angle on both ends for JIC-style tubing connections
• Flare x Flare end connection for straight tube-to-tube union
• 1/2-inch tube OD with 3/8 x 1/2 thread sizing
• 6000 psi maximum dynamic working pressure
• Steel construction for strength and resistance to pressure cycling
• Sold in a package quantity of 5

Compatibility

Designed as an OEM-style replacement or service fitting for hydraulic and fluid power tubing systems utilizing 37-degree flare connections with a 1/2-inch tube OD.

Installation Notes

Installation should be performed by a qualified hydraulic technician or pipefitter familiar with high-pressure tubing assemblies. Depressurize and isolate the hydraulic circuit completely before disassembling any fittings or tube ends. Ensure both mating tube ends are properly flared to 37 degrees with no cracks, burrs, or deformation before assembly. Tighten fittings to the fitting manufacturer recommendations and verify the assembly for leaks before returning the system to service.
