Parker 6-6 Vlo-s 45 Degree Male Elbow 3/8-18 Nptf Orfs

Product Description

The PARKER 6-6 VLO-S is a 45-degree male elbow compression fitting designed for high-pressure hydraulic and fluid system connections. It transitions between an O-Ring Face Seal (ORFS) end and a 3/8-18 NPTF male thread, providing a leak-resistant interface in demanding fluid power applications. Constructed from zinc-plated steel, it handles working pressures up to 6000 psi. The 3/8 inch tube outside diameter and NPTF thread standard make it a standard choice for hydraulic plumbing, industrial fluid lines, and mobile equipment installations. Licensed plumbers, hydraulic technicians, and industrial pipe fitters are the typical installers of this fitting type.

This fitting is suited for use in hydraulic systems, fluid power circuits, and industrial piping assemblies where a 45-degree directional change is required at a port or panel connection. The ORFS end provides a metal-to-metal seal with an O-ring for zero-leak performance, while the NPTF thread ensures a dry, pressure-tight connection on the pipe side. Common applications include mobile hydraulic equipment, industrial machinery, and high-pressure fluid distribution manifolds.

Key Features

• 45-degree male elbow geometry for directional routing in tight plumbing layouts
• ORFS x NPTF end connections for a dual-standard, leak-resistant joint
• Rated to 6000 psi maximum working pressure
• Zinc-plated steel construction for corrosion resistance in industrial environments
• 3/8-18 NPTF thread size for compatibility with standard pipe port fittings
• 3/8 inch tube outside diameter compression end

Compatibility

Designed as an OEM-style replacement or new-installation fitting for hydraulic and fluid power systems requiring a 3/8 inch ORFS to 3/8-18 NPTF 45-degree male elbow transition.

Installation Notes

Installation should be performed by a qualified hydraulic technician or licensed pipefitter. Depressurize and isolate the fluid system completely before removing or installing any fitting. Inspect the O-ring seating surface and NPTF threads for damage before assembly, and ensure the O-ring is properly seated on the ORFS face to achieve a leak-free connection. Follow applicable fluid power system codes and equipment manufacturer guidelines for torque and assembly procedures.
