Parker BD-PT-00250 Steel Male Adapter 1-1/4 in Flare X Nptf

Product Description

The PARKER BD-PT-00250 is a steel flared tube male adapter designed to connect a 37-degree flared tube end to a female NPTF threaded port. With a 1-1/4 inch tube outside diameter and a 1-1/2-11-1/2 NPTF thread, this fitting provides a reliable metal-to-metal seal in high-pressure hydraulic and fluid power systems. It is rated for a maximum working pressure of 3000 psi and a maximum working temperature of 500 degrees F, making it suitable for demanding industrial and mobile hydraulic applications. Licensed plumbers, pipefitters, and hydraulic system technicians install this type of adapter when transitioning between flared tubing and NPT-threaded components.

This adapter is used in hydraulic lines, fuel systems, and fluid conveyance assemblies where a 37-degree flare fitting must mate with an NPTF port. Typical installations include mobile equipment, industrial machinery, and fluid power circuits requiring secure, leak-resistant connections under sustained pressure. The NPTF thread form provides a dry-seal connection without requiring additional sealant tape in many applications, though job-site practice and system requirements should always govern.

Key Features

• 37-degree flare angle on the tube end meets SAE J514 and SAE 070102 standards
• NPTF dry-seal male thread eliminates reliance on tape or paste in compatible ports
• Rated to 3000 psi maximum working pressure for high-pressure hydraulic service
• Maximum working temperature of 500 degrees F supports hot fluid and steam-adjacent applications
• Steel construction provides strength and durability in industrial environments
• Complies with ISO 8434-2, SAE 070102, and SAE J514

Compatibility

Designed as an OEM-style replacement or new-installation fitting for hydraulic and fluid power systems requiring a 37-degree flare tube connection to a 1-1/2-11-1/2 NPTF female port.

Installation Notes

Installation should be performed by a licensed pipefitter, hydraulic technician, or qualified mechanic familiar with high-pressure fluid systems. Always depressurize and drain the system before removing or installing any fitting. Inspect the mating NPTF port and flared tube end for damage, burrs, or contamination before assembly. Torque to the fitting manufacturer and system designer specifications — do not over-tighten steel fittings, as this can distort the flare seat and cause leaks.
