Enerpac A604 Hydraulic Hose Coupler Set 10000 Psi 3/8 in

Product Description

The ENERPAC A604 is a regular-flow hydraulic hose coupler set rated for 10,000 psi working pressure, designed for use in high-pressure hydraulic tool circuits. Machined from steel with NPTF threaded connections, the A604 provides a secure, leak-resistant coupling point between hydraulic hose lines and hand-operated or power-driven hydraulic pumps. The set measures 3.09 inches in overall length and is sized for 3/8-inch hose. Licensed hydraulic tool technicians and industrial mechanics install this coupler set when connecting or servicing hydraulic circuits on pressing, lifting, and tensioning equipment.

The A604 is suited for high-pressure hydraulic systems operating in industrial, construction, and maintenance environments. Its straight-body configuration and NPTF thread type make it compatible with standard 3/8-inch hydraulic hose assemblies. Per the manufacturer, it is intended for use with hand pumps in the ENERPAC Series A product line. It is appropriate for both shop bench applications and field service work where a compact, threaded coupler set is required.

Key Features

• Rated to 10,000 psi maximum working pressure for high-pressure hydraulic circuits
• Steel construction for durability in demanding industrial and field service environments
• NPTF threaded connection type for leak-resistant sealing without additional sealant tape in many applications
• 3/8-inch hose size with straight-body profile for straightforward hose routing
• Maximum flow rate of 7.60 LPM suitable for regular-flow hydraulic tool circuits
• Compact overall length of 3.09 inches for installations with limited clearance

Compatibility

Designed for use with ENERPAC Series A hand pumps as stated by the manufacturer. Fits standard 3/8-inch NPTF-threaded hydraulic hose assemblies in regular-flow high-pressure circuits rated to 10,000 psi.

Installation Notes

Installation should be performed by a qualified hydraulic technician or industrial mechanic familiar with high-pressure hydraulic systems. Before servicing any hydraulic connection, relieve all pressure from the circuit and verify the system is fully depressurized. NPTF threads are designed for pressure-tight metal-to-metal sealing, but inspect threads for damage and confirm torque with calibrated tooling per system manufacturer guidelines. Do not exceed the rated working pressure of the coupler or any connected component in the circuit.
