Parker 16 Elo-s Compression Tube Union 1 in Od Orfs

Product Description

The PARKER 16 ELO-S is a compression tube union designed for high-pressure hydraulic and fluid system plumbing. It connects two tube ends of equal outside diameter using an O-Ring Face Seal (ORFS) end connection, which provides a leak-resistant metal-to-metal and elastomer seal. Built from steel with a UNF thread standard, this union is rated for working pressures up to 6000 psi, making it suitable for demanding industrial and mobile hydraulic applications. Installation is performed by licensed plumbers, pipefitters, or hydraulic system technicians working on tube assemblies requiring reliable, vibration-resistant connections.

This union is used in hydraulic circuits, fluid power systems, and high-pressure tubing assemblies where a straight inline tube connection is required. The ORFS configuration is common in mobile equipment, industrial machinery, and heavy-duty fluid systems where pressure integrity and leak prevention are critical. It accepts 1 inch tube outside diameter and is sold individually.

Key Features

• O-Ring Face Seal (ORFS) end connections provide a leak-resistant seal under high pressure
• Rated for up to 6000 psi maximum working pressure
• Steel construction for strength and durability in demanding fluid system environments
• UNF thread standard for consistent fitment with standard hydraulic tube fittings
• Accepts 1 inch tube outside diameter for inline union connections
• Sold as a single unit with no minimum order requirement beyond one piece

Compatibility

Designed as an OEM-style replacement or direct-fit union for hydraulic and fluid power tube assemblies using 1 inch OD tubing with O-Ring Face Seal connections and UNF thread standard.

Installation Notes

Installation should be performed by a qualified pipefitter, plumber, or hydraulic technician. Depressurize and isolate the hydraulic circuit completely before disconnecting any fittings or tube ends. Inspect the O-ring sealing surface for nicks or debris before assembly, as surface damage will compromise the seal. Follow applicable fluid power standards and system manufacturer torque guidance when tightening compression fittings.
