Parker 8 Stx-s Steel Male Branch Tee 1/2 in Tube Od

Product Description

The PARKER 8 STX-S is a steel male branch tee fitting designed for flared tube connections in high-pressure fluid and pneumatic systems. It features a 37-degree flare angle with Flare x MNPTF end connections, making it a standard choice for hydraulic and instrumentation lines that require a reliable, leak-resistant joint. The fitting handles a maximum working pressure of 6000 psi and withstands temperatures up to 500 degrees F, giving it broad utility across demanding industrial and mechanical service environments. Plumbers, pipefitters, and hydraulic technicians install this type of fitting where a branch connection is needed off a main line run.

This fitting is suited for use in hydraulic systems, refrigeration lines, and compressed air or fluid distribution circuits where NPTF thread integrity and flared tube connections are specified. The 1/2 inch tube OD and 3/8 NPTF male thread sizing fits common tubing runs in both light industrial and heavy-duty commercial applications. It is a single-piece, sold-individually fitting appropriate for new installations and replacement service work where a branch takeoff is required.

Key Features

• 37-degree flare angle meets ISO 8434-2, SAE J514, and SAE 070425 standards
• Rated to 6000 psi maximum working pressure for high-pressure system use
• Rated to 500 degrees F maximum working temperature
• Steel construction for durability in demanding service environments
• Flare x MNPTF end connections for secure, leak-resistant joints
• 2.5 inch overall length in a compact male branch tee configuration

Compatibility

Designed as an OEM-style replacement or new-installation fitting for hydraulic and fluid systems requiring 1/2 inch OD flared tube connections with 3/8 NPTF male thread at the branch port.

Installation Notes

Installation should be performed by a qualified pipefitter or hydraulic technician. De-pressurize and isolate the system completely before removing or installing any fittings. Ensure tube ends are properly flared to 37 degrees before assembly to achieve a leak-free connection. Follow applicable standards and local codes when working with high-pressure hydraulic or pneumatic circuits.
