Parker PT-00392 Steel Flared Tube Nut 3/8 in 37 Degree

Product Description

The PARKER PT-00392 is a steel flared tube nut designed for use with 3/8 inch outside diameter tubing at a 37-degree flare angle. It provides a secure, leak-resistant mechanical connection at the flare end of hydraulic, pneumatic, or fluid transfer lines. Rated to 7500 psi maximum working pressure and 500 degrees F maximum working temperature, this nut suits demanding industrial and fluid power applications. Licensed plumbers, hydraulic technicians, and HVAC-R service pros install this type of fitting when assembling or servicing flared tube connections. Sold in packages of 5.

This fitting is suited for high-pressure fluid lines requiring reliable flare-end connections. Typical install scenarios include hydraulic circuits, refrigeration line sets, fuel lines, and compressed air systems where 37-degree JIC or SAE-style flare fittings are specified. The 37-degree flare angle conforms to ISO 8434-2, SAE J514, SAE 070118, and SAE 080118 standards, making it compatible with tubing assemblies built to those specifications. It is appropriate for both industrial and mobile equipment applications.

Installation Notes

Installation is typically performed by licensed plumbers, hydraulic technicians, or HVAC-R technicians working on flared tube assemblies. De-pressurize and isolate the line before disassembly or connection. Use a calibrated flaring tool to ensure the tube end meets the 37-degree flare angle specification before threading the nut. Do not overtighten; follow applicable SAE or system manufacturer torque guidelines for the line size in use.
