Enerpac AH654 Hydraulic Male Coupler 10000 Psi 1/4 in

Product Description

The ENERPAC AH654 is a straight, threaded, regular-flow male coupler designed for high-pressure hydraulic hose connections. Built from stainless steel, this fitting carries a 10,000 psi pressure rating and uses a 7/16-20 UNF thread pattern on a 1/4-inch hose size. The AH654 belongs to ENERPAC's AH series and is intended for use in demanding hydraulic circuits where corrosion resistance and reliable sealing under pressure are required. Licensed hydraulic technicians and industrial maintenance professionals install this fitting as part of hose assembly and circuit connection work on hydraulic power sources and workholding systems.

The AH654 is suited for hydraulic power source connections and workholding cylinder circuits. Its straight-body geometry makes it appropriate for direct inline hose-to-port installations where space allows a non-angled approach. The stainless steel construction supports use in environments where mild corrosives, washdowns, or elevated humidity could degrade carbon steel fittings. This coupler is packaged as a single unit and is sold individually, making it a straightforward replacement or addition to an existing hydraulic hose assembly.

Compatibility

Designed for use with hydraulic power sources and workholding cylinders as stated by the manufacturer. Intended for 1/4-inch hydraulic hose assemblies requiring a 7/16-20 UNF regular-flow male coupler connection.

Installation Notes

Installation should be performed by a qualified hydraulic technician familiar with high-pressure fluid power systems. Depressurize and isolate the hydraulic circuit completely before removing or installing any fitting. Use appropriate thread sealant compatible with hydraulic fluid and stainless steel as required by the circuit design. Follow all applicable fluid power safety standards and the equipment manufacturer's service procedures when assembling hydraulic hose connections.
