Parker -16422 Steel Flared Tube Adapter 1/2 in 3/8-19 Bspp

Product Description

The PARKER -16422 is a steel flared tube adapter designed to connect a 1/2-inch OD flared tube to a 3/8-19 male BSPP threaded port. The fitting uses a 37-degree flare geometry and delivers a reliable metal-to-metal seal in high-pressure hydraulic and fluid power systems. Rated to 6000 psi maximum working pressure and 500 degrees F, this adapter handles demanding operating conditions found in industrial and mobile hydraulic circuits. It ships in a package quantity of two and is suitable for use by hydraulic technicians, plumbers, and mechanical contractors working with metric or BSP-threaded equipment.

This adapter is a Flare x BSPP end connection fitting, bridging SAE-style 37-degree flared tubing to British Standard Parallel Pipe threads. Typical installations include hydraulic power units, fluid transfer lines, and equipment imported or engineered to BSP thread standards. The 37-degree flare conforms to SAE J514 and ISO 8434-2, making it appropriate for both domestic and internationally specified hydraulic assemblies. The compact overall length of approximately 1.52 inches keeps the fitting profile low in tight plumbing layouts.

Key Features

• 37-degree flare end meets SAE J514 and ISO 8434-2 standards
• 6000 psi maximum working pressure for high-pressure hydraulic service
• 500 degrees F maximum working temperature
• Male BSPP thread for compatibility with BSP-threaded ports and valves
• Steel construction for durability in demanding fluid power environments
• Ships in a package of 2 units

Compatibility

Designed as an OEM-style replacement or replacement fitting for hydraulic systems using 1/2-inch OD 37-degree flared tubing and 3/8-19 male BSPP threaded connections conforming to SAE J514 and ISO 8434-2.

Installation Notes

Installation should be performed by a qualified hydraulic technician or pipefitter. Depressurize and isolate the hydraulic circuit fully before removing or installing any fittings. Inspect the flare seat and BSPP threads for damage before assembly, and ensure the mating port thread standard is BSPP before installation, as BSPP and NPT threads are not interchangeable. Follow SAE J514 assembly procedures for flared tube connections to achieve a proper leak-free seal.
