Parker 12-4 Trlon-s Tube End Reducer Orfs Steel

Product Description

The PARKER 12-4 TRLON-S is a compression-style tube end reducer with an O-Ring Face Seal (ORFS) end connection. It is designed to reduce tubing from a 3/4 inch outside diameter to a 1/4 inch outside diameter within hydraulic or fluid-power lines. Constructed from steel, this fitting is rated to a maximum working pressure of 6000 psi, making it suitable for high-pressure applications. It uses UNF thread standards and relies on a face-seal O-ring interface to prevent leakage under pressure. Licensed plumbers, hydraulic system technicians, and fluid-power specialists are the typical installers of this fitting type.

This tube end reducer is used in hydraulic plumbing circuits, fluid-power systems, and related industrial or mobile equipment lines where a transition between two different tube outside diameters is required. The ORFS connection style provides a reliable, leak-resistant seal compared to flared or NPT alternatives, making it a common choice in high-pressure hydraulic assemblies found in both stationary and mobile equipment installations.

Key Features

• Reduces tube outside diameter from 3/4 inch to 1/4 inch in a single fitting
• O-Ring Face Seal (ORFS) end connection for reliable, leak-resistant performance at high pressure
• Steel construction for durability in demanding hydraulic and fluid-power environments
• Maximum working pressure rating of 6000 psi
• UNF thread standard for broad compatibility with standard hydraulic components
• Single-piece unit — package quantity of 1

Compatibility

Designed as an OEM-style replacement or direct-install fitting for hydraulic and fluid-power plumbing systems using O-Ring Face Seal connections with UNF threading and tube outside diameters of 3/4 inch and 1/4 inch.

Installation Notes

Installation should be performed by a qualified hydraulic technician or licensed plumber familiar with high-pressure fluid-power systems. Depressurize and isolate the hydraulic circuit completely before removing or installing any fitting. Inspect the O-ring seating face for nicks, burrs, or contamination before assembly, as face-seal integrity depends on a clean mating surface. Follow the equipment manufacturer's assembly procedures and any applicable industry standards for hydraulic fittings.
