Built from steel with a threaded connection type, this fitting accepts a 5\/8-inch hose and uses a 1-1\/16-12 thread size. It carries a maximum working pressure of 3,625 psi and supports a maximum flow rate of 20.00 GPM. At 3.7 inches overall length and 1.4 pounds, this coupler is sized for compact integration into hydraulic circuits. Licensed hydraulic technicians and equipment mechanics install this fitting in high-pressure fluid power systems where a reliable, leak-resistant straight thread connection is required.\u003c\/p\u003e\u003cp\u003eThis coupler is suited for use with hydraulic tools and skid loader attachments in both mobile and stationary hydraulic systems. Its straight body profile and SAE shaft type make it a practical choice for inline hose terminations where space constraints or routing angles call for a no-bend connection point. The FEM series coupler conforms to ISO 16028, making it appropriate for applications where standardized quick-disconnect performance is specified. Typical installations include construction equipment, agricultural machinery, and industrial hydraulic power units.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMaximum working pressure of 3,625 psi for high-demand hydraulic circuits\u003c\/li\u003e\n\u003cli\u003eMaximum flow rate of 20.00 GPM\u003c\/li\u003e\n\u003cli\u003eSteel construction for durability in harsh service environments\u003c\/li\u003e\n\u003cli\u003e1-1\/16-12 thread size with straight body geometry for simplified routing\u003c\/li\u003e\n\u003cli\u003eConforms to ISO 16028 standard\u003c\/li\u003e\n\u003cli\u003eCompatible with 5\/8-inch hydraulic hose\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with hydraulic tools and skid loader attachments.

Depressurize and de-energize the hydraulic circuit fully before disconnecting or installing any fittings. Verify thread engagement and torque to the system manufacturer's specifications using calibrated hand tools. Inspect the connection for leaks before returning the system to service.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFitting Type\u003c\/strong\u003e: Female Straight Thread Coupler\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHose Size\u003c\/strong\u003e: 5\/8 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1-1\/16-12\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoupler Size\u003c\/strong\u003e: 0.625 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Working Pressure\u003c\/strong\u003e: 3,625 psi\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Flow Rate\u003c\/strong\u003e: 20.00 GPM\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.7 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody Diameter\u003c\/strong\u003e: 5\/8 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShape\u003c\/strong\u003e: Straight\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnection Type\u003c\/strong\u003e: Threaded\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShaft Type\u003c\/strong\u003e: SAE\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ISO 16028\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: FEM\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.4 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: PARKER\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: FEM-621-12FO-NL\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51539513311538,"sku":"FEM-621-12FO-NL","price":168.59,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/72d2a84d591a7bec173af63b300953e0.jpg?v=1785842277","url":"https:\/\/voomisupply.com\/products\/parker-fem-621-12fo-nl-female-straight-thread-coupler","provider":"Voomi Supply","version":"1.0","type":"link"}
