Parker PQ-00104 Hydraulic Hose Coupler 1200 Psi Brass Nptf

Product Description

The PARKER PQ-00104 is a brass hydraulic hose coupler designed for fluid power systems requiring a reliable threaded connection at up to 1,200 psi working pressure. Built to Series ST specifications, this coupler features a 1-inch hose diameter with a 1-11-1/2 NPTF thread interface, providing a pressure-tight seal without the need for additional sealant tape on properly gauged fittings. At 2.53 inches overall length and a rated maximum flow rate of 50.00 GPM, it suits moderate- to high-flow hydraulic circuits in mobile and industrial applications. Licensed hydraulic system technicians and pipefitters are the typical installers.

This coupler is suited for hydraulic plumbing in industrial machinery, mobile equipment, and fluid transfer systems where a brass NPTF threaded connection is specified. The NPTF thread form is engineered for dry-seal performance, making it a common choice in hydraulic and pneumatic circuits where leak-free joints are critical. The 16 mm hose size and 1-inch coupler diameter align with mid-range hydraulic hose assemblies used across a wide range of stationary and mobile platforms.

Key Features

• Maximum working pressure of 1,200 psi for demanding hydraulic circuits
• Brass construction provides corrosion resistance in fluid power environments
• 1-11-1/2 NPTF thread delivers dry-seal performance without external thread sealant
• Maximum flow rate of 50.00 GPM supports moderate- to high-volume hydraulic lines
• Series ST design for consistent dimensional interchangeability
• Compact 2.53-inch overall length minimizes installation envelope

Compatibility

Designed as an OEM-style replacement or service fitting for hydraulic hose assemblies requiring a 1-inch NPTF threaded brass coupler rated to 1,200 psi.

Installation Notes

Installation should be performed by a qualified hydraulic technician or pipefitter familiar with fluid power system safety practices. Depressurize and bleed the hydraulic circuit fully before removing or installing any fittings. NPTF threads are designed for dry-seal assembly; inspect thread condition and use appropriate torque practices per the system manufacturer's specifications. Follow applicable industry standards and local codes governing hydraulic plumbing installations.
