Parker 4-6 Clo-s Male Elbow Orfs X Nptf 6000 Psi

Product Description

The PARKER 4-6 CLO-S is a compression tube male elbow fitting designed for high-pressure hydraulic and fluid power plumbing. It connects a 1/4-inch OD tube to a 3/8-18 NPTF male threaded port using an O-Ring Face Seal (ORFS) tube-end connection. The zinc-plated steel construction provides corrosion resistance in demanding service environments. Rated to 6000 psi maximum working pressure, this fitting is suited for high-pressure lines where leak-free performance at threaded connections is required. Licensed plumbers, pipefitters, and hydraulic technicians install this type of fitting in industrial, mobile equipment, and fluid power systems.

This elbow fitting is used where a 90-degree directional change is needed between a compression tube line and an NPTF-threaded port. Typical applications include hydraulic power units, mobile equipment hydraulics, industrial machinery fluid lines, and high-pressure lubrication systems. The ORFS end provides a metal-to-metal seal backed by an O-ring for reliable leak prevention, while the NPTF thread end seals on thread engagement without requiring additional sealant tape in many configurations.

Key Features

• Rated to 6000 psi maximum working pressure for high-pressure hydraulic service
• ORFS tube-end connection provides reliable leak-free sealing at the tube interface
• 3/8-18 NPTF male thread end seals on thread form for pressure-tight port connections
• Zinc-plated steel construction resists corrosion in industrial and mobile equipment environments
• 90-degree male elbow configuration routes tubing efficiently in tight installations
• 1/4-inch tube outside diameter compatibility for standard small-bore hydraulic lines

Compatibility

Designed as an OEM-style replacement or service fitting for hydraulic and fluid power systems requiring a 1/4-inch OD tube ORFS connection to a 3/8-18 NPTF male port at up to 6000 psi working pressure.

Installation Notes

Installation should be performed by a qualified pipefitter, hydraulic technician, or licensed plumber familiar with high-pressure fluid systems. Depressurize and drain the system completely before removing or installing any fittings. Inspect the O-ring sealing surface and the NPTF threads for damage before assembly, and apply thread sealant to NPTF threads per manufacturer and applicable fluid power system guidelines. Follow ASME, ANSI, and applicable hydraulic system codes for pressure ratings and fitting torque procedures.
