Parker 10 Jtx-s Steel Flared Tube Union 5/8 in 37 Degree

Product Description

The PARKER 10 JTX-S is a steel flared tube union designed for high-pressure hydraulic and fluid power tubing connections. This three-end union joins tubing sections using a 37-degree flare seat on all three ports, creating a reliable metal-to-metal seal. The fitting is rated for a maximum working pressure of 5000 psi, making it suitable for demanding industrial and mobile equipment applications. Constructed from steel for durability under pressure cycling and vibration, this union is installed by hydraulic technicians, pipefitters, and HVAC or refrigeration mechanics working with flared tubing systems.

This union is used in applications where a single tubing run must branch or connect to two additional lines at a junction point. Typical installations include hydraulic power units, mobile equipment plumbing, and refrigeration or HVAC systems that use flared tubing connections. The 5/8-inch tube OD sizing fits standard tubing in medium-flow hydraulic and fluid circuits. All three connection ends accept 37-degree JIC-style flared tubing, consistent with SAE J514 flare fitting standards commonly found in industrial and commercial fluid systems.

Key Features

• 37-degree flare seat on all three ends provides a leak-resistant metal-to-metal seal
• 5000 psi maximum working pressure rating for high-pressure fluid power circuits
• Steel construction resists pressure cycling, vibration, and mechanical stress
• Flare x Flare x Flare end configuration allows three-way tubing junction without additional adapters
• 5/8-inch tube OD sizing matches standard medium-bore hydraulic and refrigeration tubing

Compatibility

Designed as an OEM-style replacement or direct-install fitting for fluid power and hydraulic systems using 5/8-inch OD tubing with 37-degree JIC flare connections.

Installation Notes

Installation should be performed by a qualified hydraulic technician or pipefitter. Depressurize and isolate the hydraulic or fluid circuit completely before disassembling any fittings. Use a properly calibrated flaring tool to ensure the 37-degree flare cone is formed correctly on the tubing end before assembly. Hand-tighten the flare nut first, then torque to the fitting manufacturer specification using an appropriate crow-foot or flare-nut wrench to avoid distorting the flare seat.
