Parker PT-00337 Steel Bulkhead Union 1/2 Inch 37 Degree Flare

Product Description

The PARKER PT-00337 is a steel flared tube bulkhead union designed to connect tubing routed through a panel, bulkhead, or wall in high-pressure hydraulic and pneumatic systems. It features a 37-degree flare angle with flare x flare end connections on both sides, allowing a secure, leak-resistant joint without welding or additional fittings. Rated to 6000 psi maximum working pressure and capable of handling temperatures up to 500 degrees F, this fitting suits demanding industrial and fluid-power applications. Licensed plumbers, pipefitters, and hydraulic system technicians install this type of fitting in fabricated assemblies and equipment enclosures.

This bulkhead union is suited for hydraulic lines, fuel systems, and instrumentation tubing requiring a pass-through connection at a panel or chassis. The 1/2 inch tube OD sizing is common in mid-range hydraulic and pneumatic circuits. The 37-degree flare design conforms to SAE J514 and ISO 8434-2 standards, making it a direct fit in systems built to those specifications. The overall installed length of 2.24 inches keeps the assembly compact in tight mounting locations.

Compatibility

Designed for use in hydraulic and pneumatic tubing systems with 1/2 inch OD tubing and 37-degree flare end connections conforming to SAE J514 and ISO 8434-2 specifications.

Installation Notes

Installation is typically performed by licensed pipefitters, hydraulic technicians, or plumbers familiar with high-pressure flare fittings. Depressurize and isolate the system completely before removing or installing any fitting. Ensure mating flare seats are clean and free of burrs or damage before assembly. Refer to SAE J514 torque and assembly guidelines for proper flare connection procedure.
