Parker -16420 Steel Flared Tube Adapter 1/2 in M18 37 Deg

Product Description

The PARKER -16420 is a steel flared tube adapter designed for high-pressure hydraulic and fluid power lines. It connects 1/2 inch OD tubing with a 37-degree flare end to a Male ISO 6149 M18 threaded port. Rated to 5000 psi maximum working pressure and a maximum working temperature of 500 degrees F (260 degrees C), this fitting is built for demanding industrial and mobile hydraulic applications. It meets ISO 6149, ISO 8434-2, SAE J514, and SAE 070187 standards, making it a reliable choice for systems where verified pressure ratings and standardized thread forms are required.

This adapter is suited for use in hydraulic systems found in industrial machinery, mobile equipment, and fluid power circuits where a flare-to-port transition is needed. It bridges 37-degree JIC-style flare tubing connections to ISO 6149 metric threaded ports. Licensed HVAC, plumbing, and hydraulic technicians working on high-pressure fluid circuits will encounter this fitting type in both new installations and service work. Each package contains 2 pieces.

Key Features

• 37-degree flare end connection for JIC-style tube fittings with 1/2 inch OD tubing
• Male ISO 6149 M18 thread for direct port connections on hydraulic components
• 5000 psi maximum working pressure for high-pressure hydraulic service
• 500 degrees F (260 degrees C) maximum working temperature rating
• Steel construction for strength and durability in fluid power applications
• Compliant with ISO 6149, ISO 8434-2, SAE J514, and SAE 070187 standards

Compatibility

Designed for hydraulic and fluid power systems requiring a 37-degree flare tube connection to a Male ISO 6149 M18 threaded port. Suitable for use wherever ISO 8434-2 and SAE J514 flare fittings with 1/2 inch OD tubing are specified.

Installation Notes

Installation should be performed by a qualified hydraulic technician or pipefitter familiar with high-pressure fluid system assembly. Depressurize and isolate the hydraulic circuit fully before removing or installing any fittings. Inspect flare seats and threads for damage before assembly, and ensure tube flares are formed to the correct 37-degree angle. Follow applicable SAE and ISO torque and assembly procedures for flare fittings.
