The Enerpac CH-604 is the standard male coupler half for the C-Series high-flow hydraulic coupler system, used on most Enerpac pumps and cylinders rated to 10,000 psi (700 bar). The 3/8-inch NPTF male thread enables direct connection to Enerpac hydraulic hoses and tooling without adapters, and the high-flow design supports up to 2,500 in³/min (35 l/min) to minimize pressure loss during cylinder operations.

Each CH-604 ships with a 2-in-1 dust cap that fits both male and female coupler halves, protecting the hydraulic connection from contamination during storage and transport. The CH-604 pairs with the CR-400 female coupler (standard-equipped on RC, RCH, RSM, and many other Enerpac cylinders) to form a complete, rated connection.

Best For:

- Connecting Enerpac hydraulic hoses to RC, RCH, RSM, and P-series cylinders and pumps

- Replacing lost or worn male coupler halves in existing Enerpac hydraulic setups

- Field service and maintenance kits requiring spare 3/8 NPTF male couplers

- Any 10,000 psi hydraulic system using Enerpac C-Series coupler standards

- Applications requiring fast, repeated hose connect/disconnect cycles

Key Features:

- 3/8 NPTF male thread: standard port connection for Enerpac pumps, cylinders, and hydraulic hoses throughout the 10,000 psi tooling range

- High-flow design: 2,500 in³/min (35 l/min) maximum flow capacity reduces pressure drop during cylinder advance and retract

- 10,000 psi (700 bar) rated: compatible with full Enerpac system operating pressure

- C-Series standard: OEM-spec coupler used on most Enerpac cylinders and pumps as factory standard equipment

- 2-in-1 dust cap: single cap protects both male and female coupler halves — included with each CH-604

Q: What is the CH-604 used for?

A: The CH-604 is the male hose-side half of the Enerpac C-Series high-flow hydraulic coupler. It connects a hydraulic hose to an Enerpac pump or cylinder equipped with a CR-400 female coupler, forming a rated 10,000 psi quick-connect coupling.

Q: What thread does the CH-604 use?

A: The CH-604 has a 3/8 NPTF male thread for connection to Enerpac hydraulic hoses and compatible fittings.

Q: Is the CH-604 compatible with Enerpac RC-series cylinders?

A: Yes. Enerpac RC, RCH, RSM, and many other cylinder series are factory-equipped with the CR-400 female coupler. The CH-604 male half connects directly to the CR-400 to form a complete, rated hydraulic coupling.

Q: What is the maximum operating pressure of the CH-604?

A: The CH-604 is rated to 10,000 psi (700 bar) maximum operating pressure.

Q: What is the flow capacity of the CH-604?

A: The CH-604 supports a maximum flow capacity of 2,500 in³/min (35 l/min) for low-restriction hydraulic connections.

Q: Does the CH-604 include a dust cap?

A: Yes. The CH-604 ships with a 2-in-1 dust cap that fits both male and female coupler halves, protecting the port from contamination during storage and transport.

Q: Is the CH-604 the male or female coupler half?

A: The CH-604 is the male half (hose side) of the C-Series coupler. The matching female half is the CR-400, which is standard-equipped on most Enerpac cylinders.

Q: Do I need the CH-604 if my cylinder already has a CR-400?

A: Yes. The CR-400 female coupler is already on the cylinder. The CH-604 male coupler is required on the hose end to connect the hydraulic hose from the pump to the cylinder.
