Parker 10 Wtx-s Steel Bulkhead Union 5/8 in 37 Degree Flare

Product Description

The PARKER 10 WTX-S is a steel flared tube bulkhead union designed to pass hydraulic or fluid lines through a panel, bulkhead, or wall while maintaining a secure, leak-resistant connection. It uses a 37-degree flare angle on both ends, conforming to SAE J514 and ISO 8434-2 standards. The fitting accepts 5/8-inch tube OD and is rated for a maximum dynamic working pressure of 5000 psi and a maximum working temperature of 500 degrees F. Licensed plumbers, hydraulic technicians, and fluid power specialists install this type of fitting in high-pressure tubing systems where a clean panel penetration is required.

This bulkhead union is suited for industrial, mobile hydraulic, and fluid transfer applications where tubing must pass through a partition or equipment enclosure. The flare-by-flare end configuration allows direct connection to standard 37-degree flared tube ends on both sides of the panel. It is appropriate for use in systems operating at elevated temperatures and pressures within the rated limits, including hydraulic circuits, refrigeration lines, and fuel systems.

Compatibility

Designed as an OEM-style replacement or new-installation bulkhead union for 37-degree flared tube assemblies with 5/8-inch tube OD, per SAE J514 and ISO 8434-2 standards.

Installation Notes

Installation should be performed by a qualified hydraulic technician or licensed tradesperson familiar with flared tube fitting assemblies. Depressurize and drain the system fully before removing or installing any fittings. Ensure the bulkhead panel hole is properly sized and deburred before inserting the fitting, and secure the locknut to the panel before making tube connections. Follow SAE J514 torque guidelines for flared fittings and inspect both flare seats for damage before assembly.
