Parker 12-10 Trlon-s Tube End Reducer Orfs Steel

Product Description

The PARKER 12-10 TRLON-S is a steel tube end reducer fitting with O-Ring Face Seal (ORFS) end connections. It transitions between two different tube outside diameters — 3/4 inch and 5/8 inch — within hydraulic and fluid power lines. Built from steel with a UNF thread standard, this fitting supports a maximum working pressure of 6000 psi. It is sized for applications where a reliable, leak-resistant face seal connection is required. Licensed HVAC technicians, hydraulic system installers, and fluid power technicians working on high-pressure tube assemblies are the primary installers of this component.

This tube end reducer is suited for hydraulic systems, fluid power circuits, and industrial plumbing applications where tube diameter transitions must maintain high-pressure integrity. The ORFS design creates a seal at the face of the fitting using a bonded or seated O-ring, which reduces the risk of leakage compared to flare-type connections. It is commonly found in mobile hydraulics, industrial machinery, and refrigeration or HVAC equipment where steel fittings and UNF threads are specified.

Key Features

• O-Ring Face Seal (ORFS) end connections for reliable, leak-resistant performance at high pressure
• Reduces tube outside diameter from 3/4 inch to 5/8 inch in a single fitting
• Maximum working pressure rated to 6000 psi
• Steel construction for durability in demanding hydraulic and fluid power environments
• UNF thread standard for broad compatibility with standard hydraulic plumbing components

Compatibility

Designed as a tube end reducer for hydraulic and fluid power tube assemblies using 3/4 inch and 5/8 inch outside diameter tubing with O-Ring Face Seal connections and UNF threads.

Installation Notes

Installation of ORFS fittings should be performed by a qualified hydraulic technician or licensed tradesperson familiar with high-pressure fluid systems. Depressurize and isolate the hydraulic circuit completely before disconnecting any lines or installing this fitting. Inspect the O-ring sealing surface and the O-ring itself for damage before assembly, and replace the O-ring if any deformation or cuts are present. Follow the equipment manufacturer and applicable industry standards for assembly and torque procedures.
