Parker 4 Rtx-s Steel Flared Male Run Tee 1/4 in

Product Description

The PARKER 4 RTX-S is a steel male run tee fitting designed for flared tube connections in high-pressure fluid and pneumatic systems. It connects a 1/4-inch OD tube line using 37-degree flare ends with a male NPTF threaded branch port sized at 1/8 inch. Rated for a maximum working pressure of 6000 psi and temperatures up to 500 degrees F, this fitting is suited for demanding hydraulic and instrumentation plumbing work. Licensed HVAC technicians, plumbers, and industrial pipefitters use this style of tee when branching a tube run while maintaining inline flow continuity. The steel construction and NPTF thread standard ensure a pressure-tight, drip-free seal without sealant tape on the threaded port.

This fitting is used in residential and light commercial applications where 37-degree flare connections are specified, including refrigeration line sets, hydraulic control circuits, and compressed-air distribution systems. It is appropriate wherever a male-run tee is required to introduce a branch port off an existing 1/4-inch OD tube run. The 37-degree flare geometry conforms to SAE J514 and ISO 8434-2 standards, making it compatible with standard SAE flare tube assemblies used across HVAC, hydraulic, and industrial fluid-power installations.

Key Features

• 37-degree flare end connections conforming to SAE J514 and ISO 8434-2
• Male NPTF threaded branch port for a pressure-tight mechanical seal
• Rated to 6000 psi maximum dynamic working pressure
• Rated to 500 degrees F maximum working temperature
• 1/4-inch tube OD inline run with 1/8-inch NPTF branch thread
• Steel construction for durability in hydraulic and instrumentation service

Compatibility

Designed as an OEM-style replacement or new-installation fitting for standard SAE 37-degree flare tube assemblies using 1/4-inch OD tubing and 1/8-inch NPTF threaded branch connections.

Installation Notes

Installation should be performed by a licensed plumber, HVAC technician, or qualified pipefitter. De-energize and depressurize the system fully before disassembling any tube connections. Ensure tube ends are cut square, deburred, and properly flared to 37 degrees before seating the fitting. NPTF threads are designed for dry-seal service, but verify system requirements before applying any thread sealant.
