Parker PQ-00102 Hydraulic Hose Coupler 2200 Psi 8 Mm

Product Description

The PARKER PQ-00102 is a brass hydraulic hose coupler designed for threaded connections in hydraulic fluid systems. It features a 1/2-14 NPTF thread and accommodates a hose diameter of 1/2 inch (8 mm). Rated for a maximum working pressure of 2,200 psi, this coupler handles demanding hydraulic applications where leak-free, threaded fittings are required. The overall length is 1.94 inches. It ships in a package quantity of two and is part of the Parker ST series. Licensed hydraulic system technicians and industrial mechanics are the typical installers.

This coupler is suited for use in hydraulic circuits found in mobile equipment, industrial machinery, and fluid power systems where NPTF threaded connections are specified. The 1/2-14 NPTF thread form provides a dry-seal connection that resists leakage without relying solely on a sealant. The brass construction makes it a practical choice in applications where moderate corrosion resistance is needed alongside reliable pressure containment up to 2,200 psi.

Key Features

• Maximum working pressure rated at 2,200 psi for reliable performance in high-pressure hydraulic circuits
• 1/2-14 NPTF dry-seal thread for leak-resistant connections without supplemental sealing compounds
• Brass construction provides corrosion resistance in hydraulic fluid environments
• Maximum flow rate of 12.00 GPM supports standard mid-range hydraulic circuit demands
• Overall length of 1.94 inches keeps the installation compact in tight plumbing configurations
• Parker ST series designation ensures dimensional consistency with compatible ST series fittings

Compatibility

Designed as an OEM-style replacement or new-installation fitting for hydraulic systems requiring a 1/2-inch hose diameter, 1/2-14 NPTF threaded coupler rated to 2,200 psi.

Installation Notes

Installation should be performed by a qualified hydraulic technician or fluid power mechanic. Depressurize and isolate the hydraulic circuit completely before removing or installing any fitting. NPTF threads are designed as dry-seal connections, but inspect threads for damage before assembly and follow the fitting manufacturer's recommended thread engagement practice. Do not exceed the rated working pressure of 2,200 psi in service.
