Parker 8-12 Clo-s Compression Tube Male Elbow Orfs Nptf

Product Description

The PARKER 8-12 CLO-S is a compression tube male elbow fitting designed to connect a 1/2-inch OD tube to a 3/4-14 NPTF male port using an O-Ring Face Seal (ORFS) interface. Constructed from zinc-plated steel, it is rated for a maximum working pressure of 6000 psi, making it well-suited for high-pressure hydraulic and fluid power lines. The 90-degree elbow geometry allows direction changes in tight routing applications without bending tubing. This fitting is installed by hydraulic technicians and pipefitters working on industrial, mobile, and stationary fluid power systems.

This fitting is used in hydraulic plumbing applications where a tube line must transition to a threaded port on a valve, manifold, pump, or cylinder. The ORFS end provides a leak-free metal-to-face seal via a compressed O-ring, while the NPTF thread end creates a pressure-tight mechanical seal without additional sealant. It is appropriate for both new system builds and field repair work in industrial and mobile equipment environments.

Key Features

• Maximum working pressure rated at 6000 psi for demanding hydraulic service
• ORFS x NPTF end connections combine leak-free face sealing with tapered pipe thread engagement
• 1/2-inch tube outside diameter compression end for standard hydraulic tubing
• 3/4-14 NPTF thread size for direct port connection
• Zinc-plated steel construction provides corrosion resistance in typical hydraulic environments
• 90-degree male elbow geometry simplifies routing in space-constrained installations

Compatibility

Designed as an OEM-style replacement or new-install fitting for hydraulic and fluid power systems requiring a 1/2-inch OD tube to 3/4-14 NPTF male elbow connection with an O-Ring Face Seal interface.

Installation Notes

Installation should be performed by a qualified hydraulic technician or pipefitter. De-pressurize and bleed down the hydraulic circuit fully before removing or installing any fittings. Inspect the ORFS face and O-ring for damage before assembly; a nicked seating surface or cut O-ring will not seal reliably at high pressure. Torque the NPTF end to the system designer's specified value and verify there are no leaks before returning the system to full operating pressure.
