Parker 12 Rtx-s Steel Male Run Tee 3/4 in 37 Deg Flare

Product Description

The PARKER 12 RTX-S is a steel male run tee fitting designed for high-pressure flared tube connections in hydraulic, pneumatic, and fluid-transfer systems. It features a 37-degree flare seat with Flare x MNPTF end connections, making it compatible with standard JIC-style tubing assemblies. The fitting has a 3/4 inch tube OD and a 3/4 inch male NPTF thread on the branch end. Rated for up to 4000 psi maximum dynamic working pressure, it is suited for demanding service environments. Plumbers, pipefitters, and hydraulic system technicians install this type of fitting in both industrial and mobile equipment applications.

This fitting is used wherever a flared tube line must branch off a run while maintaining a threaded port connection. Typical applications include hydraulic power units, fuel systems, compressed-air lines, and refrigeration or HVAC fluid circuits requiring NPTF-sealed branch connections. The male run tee configuration allows the main tube run to pass through while the branch exits via a male pipe thread, reducing the need for additional adapters in tight plumbing layouts. It is appropriate for residential, commercial, and light industrial installations.

Key Features

• 37-degree flare seat conforms to JIC flare fitting standards for reliable metal-to-metal sealing
• NPTF thread standard on the male branch provides a pressure-tight, dry-seal connection without sealant tape
• Steel construction offers durability in high-pressure hydraulic and fluid-transfer service
• Rated to 4000 psi maximum dynamic working pressure
• 3/4 inch tube OD with matching 3/4 inch male NPTF thread for consistent line sizing
• Single-piece male run tee reduces fitting count in branched tube assemblies

Compatibility

Designed as an OEM-style replacement or service fitting for hydraulic and fluid-system applications using 3/4 inch OD flared tubing with 37-degree JIC-style flare seats and NPTF-threaded branch ports.

Installation Notes

Installation should be performed by a qualified pipefitter, hydraulic technician, or licensed plumber following applicable industry codes. De-pressurize and fully isolate the fluid system before disassembly or fitting installation. Inspect the flare seat and tube end for burrs or damage before assembly, as metal-to-metal flare seals require clean, undamaged seating surfaces. NPTF threads are designed for dry-seal service, but consult the system specification before applying thread sealants.
