Q/R #4 90 Deg Hose End Plug Valved Black

The JIFFY-TITE Q/R #4 90 Degree Hose End Plug Valved Black (MPN 22604JE) is a quick-release coupling designed for high-pressure hydraulic and pneumatic fluid transfer applications. This 90-degree hose end plug is engineered for systems operating at 2000 PSI, making it suitable for aerospace, automotive, industrial, and mobile equipment fluid lines where rapid connection and disconnection are critical.

The 4 AN (AN-4) port size accommodates hoses with 1/4-inch nominal bore, a standard in aviation and precision hydraulic systems. Constructed from aluminum with black anodized finish, this quick-release coupling resists corrosion and maintains visual durability in harsh environments. The integrated poppet valve design prevents fluid spillage during disconnection, reducing contamination risk and system loss—critical for systems where fluid integrity directly affects performance. The FKM elastomer seal provides chemical resistance and maintains a reliable seal across standard operating temperature ranges.

This quick-release hose end plug serves technicians and operators in aviation maintenance, hydraulic system assembly, equipment service, and fluid transfer operations. The 90-degree orientation is essential in confined spaces where straight-line connections would create interference with adjacent components. Industries relying on JIFFY-TITE quick-release couplers value their repeatability and low-spillage design—factors that extend equipment life and reduce maintenance downtime.

Quick-release fluid couplings like the 2000 Series represent an industry standard for systems where reliability under pressure is non-negotiable. The valved design distinguishes premium quick-release components from basic alternatives, ensuring minimal fluid loss and easier system integration. For operators assembling or servicing pressure systems, selecting correctly rated couplers directly impacts both safety and operational efficiency.
