Parker FEM-371-8FO Hydraulic Hose Coupler 3625 Psi 3/4-16

Product Description

The PARKER FEM-371-8FO is a female straight thread coupler designed for hydraulic hose assemblies in high-pressure fluid power systems. Constructed from steel, it provides reliable mechanical strength and corrosion resistance under demanding operating conditions. The fitting carries a pressure rating of 3,625 psi and features a 3/4-16 thread size with an SAE shaft type. A 3/8-inch body diameter makes it a compact yet capable connection point. Licensed hydraulic system technicians and industrial maintenance mechanics install this coupler when building or repairing hose assemblies on mobile equipment, industrial machinery, or stationary hydraulic power units.

This coupler is suited for hydraulic hose connections in both mobile and stationary applications where SAE straight thread fittings are specified. Typical use cases include construction equipment, agricultural machinery, and industrial press or lift systems that require secure, leak-resistant hydraulic connections rated for moderate-to-high working pressures. The steel construction handles the thermal and pressure cycling common in these environments.

Key Features

• Pressure rating of 3,625 psi for demanding hydraulic system service
• 3/4-16 thread size for positive thread engagement
• SAE shaft type ensures compatibility with standard SAE hose end configurations
• Steel construction provides durability under cyclic pressure and temperature conditions
• 3/8-inch body diameter suits compact hose assembly routing

Compatibility

Designed as an OEM-style replacement or service fitting for hydraulic hose assemblies using SAE straight thread couplers rated at or below 3,625 psi with 3/4-16 thread specifications.

Installation Notes

Installation should be performed by a qualified hydraulic technician following standard fluid power safety procedures. Depressurize and bleed down the hydraulic system fully before removing or installing any fittings. Use appropriate thread sealant or O-ring as required by the joint design, and verify thread engagement before applying system pressure. Follow applicable industry standards such as SAE J1453 for straight thread port connections.
