Parker 16 Hlo-s Compression Tube Union 1 in Od Orfs Steel

Product Description

The PARKER 16 HLO-S is a compression tube union designed for high-pressure hydraulic and fluid system applications. It connects two tube ends of equal outside diameter using an O-Ring Face Seal (ORFS) end connection, which provides a leak-free metal-to-metal seat backed by an elastomeric o-ring. Built from steel with a UNF thread standard, this fitting is rated for working pressures up to 6,000 psi, making it suitable for demanding industrial and mobile hydraulic circuits. Installation is typically performed by hydraulic system technicians or journeyman mechanics working on fluid power equipment.

This fitting is suited for use in high-pressure hydraulic lines, mobile equipment, and industrial fluid systems where a reliable tube-to-tube union is required. The ORFS design minimizes the risk of leakage at high operating pressures and is a common choice in systems subject to vibration or pressure spikes. It accepts 1 inch tube outside diameter and is sold individually.

Key Features

• O-Ring Face Seal (ORFS) end connections for leak-free performance under high pressure
• Rated to 6,000 psi maximum working pressure
• Steel construction for durability in demanding hydraulic environments
• UNF thread standard for broad compatibility with standard hydraulic hardware
• Accepts 1 inch tube outside diameter
• Compression-style union connects two tube ends without welding or flaring

Compatibility

Designed as an OEM-style replacement or service fitting for high-pressure hydraulic tube assemblies using 1 inch OD tubing with O-Ring Face Seal connections and UNF threading.

Installation Notes

Installation should be performed by a qualified hydraulic technician or mechanic. Depressurize and isolate the hydraulic circuit completely before disassembling any fittings or tube connections. Inspect the o-ring seating surface for nicks or contamination prior to assembly, as surface damage will compromise the seal. Torque the fitting according to the system designer's specifications for UNF ORFS hardware and verify for leaks before returning the system to service.
