Parker 8 Otx-s Steel Female Branch Tee 1/2 in Flare Fnptf

Product Description

The PARKER 8 OTX-S is a steel female branch tee fitting designed for flared tube connections in high-pressure hydraulic and fluid systems. It features a 37-degree flare angle with Flare x FNPTF end connections, conforming to SAE J514 and ISO 8434-2 standards. The fitting accepts a 1/2 inch tube outside diameter and uses a 3/8 NPTF female thread at the branch port. Rated for dynamic working pressures up to 4500 psi and temperatures up to 500 degrees F, this fitting suits demanding industrial and mobile equipment applications. It is typically installed by hydraulic technicians, plumbers, and fluid power specialists.

This fitting is suited for use in hydraulic lines, fuel systems, refrigeration circuits, and instrumentation tubing where a branch tee configuration is required. The NPTF thread standard ensures a dry-seal connection at the female port without relying solely on thread sealant. Its steel construction handles high-pressure dynamic loads common in mobile hydraulics, industrial machinery, and OEM fluid system assemblies. The 37-degree flare angle is consistent with JIC and SAE-style tube fittings widely used across these industries.

Key Features

• Flare x FNPTF end connections provide a secure, leak-resistant branch tee configuration
• Rated for up to 4500 psi maximum dynamic working pressure
• Operates across a wide temperature range up to 500 degrees F (260 degrees C)
• Steel construction for strength and durability in high-pressure fluid lines
• NPTF thread standard delivers a dry-seal fit at the female branch port

Compatibility

Designed as an OEM-style replacement or new-installation fitting for hydraulic and fluid systems using 1/2 inch OD flared tubing and 3/8 NPTF female branch connections in compliance with SAE J514 and ISO 8434-2.

Installation Notes

Installation should be performed by a qualified hydraulic technician or pipefitter. Depressurize and isolate the fluid system completely before removing or installing any fittings. Use proper flaring tools to ensure a correct 37-degree flare seat on the tube end before assembly. Refer to SAE J514 torque and assembly guidelines for proper connection integrity; do not overtighten, as this can damage the flare seat.
