Parker 8 Tlfa-s Seal-lok Orfs Flat-face Tube Fitting Steel

Product Description

The PARKER 8 TLFA-S is a field-attachable, compression-style tube fitting designed for O-Ring Face Seal (ORFS) flat-face end connections. Built from steel, this Seal-Lok fitting allows technicians to assemble hydraulic or fluid system connections in the field without swaging equipment. The flat-face ORFS interface delivers a leak-resistant seal by compressing an O-ring against a flat mating surface, making it well-suited for high-pressure hydraulic lines where leak-free performance is critical. Installation uses the 8 TLFA gauge and 8 TLFA mandrel tools for proper tube preparation.

This fitting is used in hydraulic fluid transmission systems found in industrial, mobile equipment, and heavy trade applications. Field-attachable fittings like the 8 TLFA-S are chosen when lines must be fabricated or repaired on-site without access to a hydraulic hose shop. The ORFS flat-face design is common in systems where vibration or pressure spikes make threaded or flare connections prone to leakage. Qualified hydraulic technicians and fluid power specialists are the primary installers.

Key Features

• Field-attachable compression design — no swaging machine required for assembly
• O-Ring Face Seal (ORFS) flat-face end connection for reliable, leak-resistant performance
• Steel construction for durability in demanding hydraulic environments
• Compatible with PARKER 8 TLFA gauge and 8 TLFA mandrel for correct tube preparation
• Compact form factor suited for tight routing and field fabrication scenarios

Compatibility

Designed for use with the PARKER 8 TLFA gauge and 8 TLFA mandrel. Fits tube ends configured for ORFS flat-face connections. Verify tube OD, wall thickness, and system pressure rating before installation.

Installation Notes

Installation should be performed by a qualified hydraulic technician or fluid power specialist. Depressurize and isolate the hydraulic circuit completely before disassembling any fittings. Use the specified 8 TLFA gauge and 8 TLFA mandrel tools to prepare the tube end to the correct geometry before attaching this fitting. Inspect the O-ring seating surface on the mating component for damage or contamination prior to final assembly.
