Parker 6-4 Trlon-s Tube End Reducer Orfs Steel

Product Description

The PARKER 6-4 TRLON-S is a compression-style tube end reducer with an O-Ring Face Seal (ORFS) end connection, manufactured from steel. This fitting reduces tubing from a 3/8-inch outside diameter to a 1/4-inch outside diameter and is rated for a maximum working pressure of 9200 psi. It is used in high-pressure hydraulic and fluid power lines where a leak-free, vibration-resistant connection is required between two different tube sizes. Installation is typically performed by hydraulic system technicians and fluid power specialists working on industrial or mobile equipment plumbing circuits.

This reducer fitting is suited for hydraulic lines, fluid transfer systems, and instrumentation plumbing that require a step-down connection between 3/8-inch and 1/4-inch OD tubing. The ORFS interface relies on a flat face and a captive O-ring to form a positive seal, making it a common choice in applications where vibration, pressure spikes, or fluid compatibility rules out flare-style fittings. It is used in both stationary industrial systems and mobile equipment hydraulic circuits.

Key Features

• Reduces 3/8-inch OD tubing to 1/4-inch OD tubing in a single fitting
• O-Ring Face Seal (ORFS) end connection provides a positive, leak-resistant seal under high pressure
• Maximum working pressure of 9200 psi suits demanding hydraulic applications
• Steel construction for durability in high-pressure fluid power service
• UNF thread standard for broad compatibility with standard hydraulic plumbing components
• Compact, single-piece design with a package quantity of one unit

Compatibility

Designed as an OEM-style replacement or service fitting for hydraulic and fluid power systems requiring a compression tube end reducer with ORFS connections and UNF threading at 3/8 x 1/4-inch tube outside diameter.

Installation Notes

Installation should be performed by a qualified hydraulic technician or fluid power specialist. Depressurize and isolate the hydraulic circuit completely before removing or installing any fittings. Inspect the O-ring sealing surface for nicks or contamination before assembly, and ensure the O-ring is properly seated to achieve a reliable face seal. Follow applicable system design codes and the fitting manufacturer torque guidelines for ORFS connections during final assembly.
