Parker 10-4 Trlon-s Tube End Reducer Orfs 5/8x1/4 6000 Psi

Product Description

The PARKER 10-4 TRLON-S is a compression-style tube end reducer with O-Ring Face Seal (ORFS) end connections, manufactured from steel. It reduces tubing from a 5/8-inch outside diameter down to a 1/4-inch outside diameter within a single fitting body. Rated to a maximum working pressure of 6000 psi, this fitting is built for high-pressure hydraulic and fluid power lines where leak-free connections are critical. The ORFS interface uses a flat face and a captive O-ring to eliminate the leak paths common in flare or compression-only designs. Licensed plumbers, hydraulic technicians, and fluid power specialists install this fitting in demanding service environments.

This reducer is suited for steel tubing assemblies in hydraulic systems, mobile equipment, industrial machinery, and fluid power circuits requiring a transition between two different tube sizes. The UNF thread standard ensures compatibility with standard ORFS port connections used throughout North American hydraulic plumbing. It is appropriate for both OEM assembly and field repair applications where high-cycle or high-pressure service is expected.

Key Features

• O-Ring Face Seal (ORFS) end connections for leak-free performance at high pressures
• 6000 psi maximum working pressure rating
• Reduces 5/8-inch OD tube to 1/4-inch OD tube in a single fitting
• Steel construction for durability in hydraulic and industrial fluid service
• UNF thread standard for broad compatibility with standard ORFS fittings
• Compact, single-piece body minimizes potential leak points in the assembly

Compatibility

Designed as an OEM-style replacement or service fitting for hydraulic and fluid power tubing assemblies using O-Ring Face Seal connections with UNF threading and 5/8-inch to 1/4-inch outside diameter tube sizes.

Installation Notes

Installation should be performed by a qualified hydraulic technician or licensed plumber familiar with high-pressure fluid systems. Depressurize and isolate the hydraulic circuit fully before removing or installing any fitting. Inspect the O-ring for nicks or damage before assembly, and ensure the flat sealing face is clean and free of debris. Follow the fitting manufacturer's assembly instructions and applicable fluid power standards for proper make-up procedure.
