Parker 6-6-6 Slo-s Male Branch Tee 3/8-18 Orfs X Nptf

Product Description

The PARKER 6-6-6 SLO-S is a compression tube male branch tee fitting designed for high-pressure hydraulic and fluid power plumbing applications. Constructed from zinc-plated steel, it provides corrosion resistance in demanding industrial environments. The fitting connects via O-Ring Face Seal (ORFS) and NPTF end connections with a 3/8-18 thread size, and is rated to a maximum working pressure of 6000 psi. This type of fitting is typically installed by hydraulic technicians, millwrights, and industrial plumbers when building or servicing fluid power circuits, manifold assemblies, and high-pressure tubing systems.

This fitting suits applications in industrial hydraulic systems, mobile equipment fluid circuits, and high-pressure plumbing assemblies where a branch connection is needed off a main tube run. The ORFS face seal design minimizes the risk of leakage under pressure, making it appropriate for systems where fluid integrity is critical. The NPTF thread provides a pressure-tight mechanical seal without relying solely on sealant compounds. Suitable for use in manufacturing, heavy equipment, and similar trade environments where robust threaded fittings are required.

Key Features

• 3/8-18 thread size for compatibility with standard hydraulic tubing and ports
• Male branch tee configuration enables a 3-way split from a single tube line
• Sold individually — package quantity of 1

Compatibility

Designed as an OEM-style compression tube male branch tee for high-pressure hydraulic and fluid power systems utilizing 3/8 inch outside diameter tubing with ORFS and NPTF threaded connections.

Installation Notes

Installation should be performed by a qualified hydraulic technician or licensed plumber familiar with high-pressure fluid systems. Depressurize and fully bleed the hydraulic circuit before removing or installing any fittings. Inspect the O-ring sealing surface for nicks or contamination prior to assembly, and replace the O-ring if damaged. Follow applicable industry standards and equipment manufacturer torque guidelines when tightening threaded connections.
