Enerpac AR650 Hydraulic Female Coupler 10000 Psi 1/4 in

Product Description

The ENERPAC AR650 is a straight, threaded, regular-flow female coupler designed for high-pressure hydraulic hose connections in industrial and workholding applications. Machined from steel, this coupler accepts a 1/4-inch NPT thread and carries a maximum working pressure of 10,000 psi, making it a dependable connection point between a hydraulic power source and downstream components such as cylinders. Its compact straight-body design keeps plumbing tight in confined spaces. Hydraulic technicians and maintenance professionals install this fitting as a service replacement or original equipment component on high-pressure hydraulic circuits. The AR series designation aligns it with ENERPAC standard-flow coupling systems.

The AR650 is suited for use with hydraulic power sources and workholding cylinders operating at high pressure in manufacturing, maintenance, and industrial tooling environments. The 1/4-inch hose size and NPT thread form are common in single-acting and double-acting cylinder circuits found on presses, pullers, tensioners, and similar equipment. This coupler is a direct-fit replacement for worn or damaged female half-couplers within the AR series coupling family.

Key Features

Compatibility

Designed for use with hydraulic power sources and workholding cylinders in the ENERPAC AR series. Fits hydraulic circuits requiring a 1/4-inch NPT female coupler rated to 10,000 psi.

Installation Notes

Installation should be performed by a qualified hydraulic technician. Fully depressurize and bleed the hydraulic system before removing or installing any coupling. Apply appropriate thread sealant to NPT threads per the system manufacturer's recommendations and tighten to the fitting manufacturer's specifications using proper hand tools. Verify there are no leaks and that the system reaches full working pressure before returning equipment to service.
