Parker FS-371-6FP Female Flush Face Coupler 3/8 in 2000 Psi

Product Description

The PARKER FS-371-6FP is a female flush face hydraulic coupler designed for high-pressure fluid transfer in demanding industrial and process applications. Part of the Parker FS Series, it features a valved, straight-body configuration with a 3/8-inch hose inside diameter and a 2,000 psi maximum working pressure. The body and wetted components are constructed from stainless steel, making it well-suited for corrosive, sanitary, or chemically aggressive media. The NPT threaded connection allows straightforward integration into standard piping systems. Licensed hydraulic technicians and industrial pipefitters are the primary installers of this fitting.

This coupler is rated for use in chemical dispensing systems, chemical processing lines, corrosive media transfer, and food processing environments. The flush face design minimizes fluid spillage and air inclusion during coupling and uncoupling, which is critical in closed-loop and contamination-sensitive systems. The stainless steel body withstands prolonged exposure to aggressive fluids that would degrade carbon steel or brass fittings. It is sold individually and carries a minimum order quantity of one unit.

Key Features

• Stainless steel body resists corrosion in chemical and food-grade service environments
• Flush face design reduces fluid loss and contamination during connect and disconnect
• Valved construction prevents flow until coupler is fully engaged
• 3/8-18 NPT threaded connection for standard piping integration
• Straight body shape simplifies in-line installation without offset adapters
• 2,000 psi working pressure rating suits medium-pressure hydraulic and process systems

Compatibility

Designed for use in chemical dispensing systems, chemical processing lines, corrosive media transfer systems, and food processing equipment as stated by the manufacturer. Part of the Parker FS Series flush face coupler family.

Installation Notes

Installation should be performed by a qualified hydraulic technician or industrial pipefitter. Depressurize and isolate the hydraulic or fluid system fully before disconnecting existing fittings or installing this coupler. Apply thread sealant appropriate for the media being transferred when making NPT connections, and tighten to the fitting manufacturer's standard practice for the pipe size. Verify the system is leak-free at working pressure before returning to service.
