Parker 4 Jtx-s Steel Flared Tube Union 1/4 in 37 Deg

Product Description

The PARKER 4 JTX-S is a steel flared tube union designed for hydraulic and fluid system plumbing where three flared tube ends must be joined at a single connection point. It accepts a 1/4 inch tube OD with a 37-degree flare angle on all three ends, conforming to ISO 8434-2, SAE 070401, and SAE J514 standards. Rated to a maximum working pressure of 7500 psi and a maximum working temperature of 500 degrees F, this union handles demanding service conditions in both industrial and mobile equipment applications. Licensed plumbers, pipefitters, and hydraulic system technicians are the typical installers.

This fitting is suited for high-pressure hydraulic lines, fuel systems, and fluid transfer plumbing in residential, commercial, and industrial settings where a three-way flared union is required. Its compact overall length of 1.78 inches makes it practical in tight routing scenarios. The Flare x Flare x Flare end configuration allows direct connection of three separate 37-degree flared tube lines without adapters. Applications include hydraulic power units, machine tool plumbing, and mobile equipment fuel and oil circuits.

Installation Notes

Installation should be performed by a qualified plumber, pipefitter, or hydraulic technician. Depressurize and isolate the fluid circuit completely before removing any existing fittings or connecting new ones. Ensure all mating tube ends are properly flared to the 37-degree angle and free of burrs or damage before assembly. Refer to applicable SAE and ISO standards for proper make-up procedures and torque guidance.
