Built from steel with a 9\/16-18 SAE thread and a 1\/4-inch body diameter, it carries a maximum working pressure of 4568 psi. The coupler measures 2.08 inches in overall length and supports a maximum flow rate of 3.00 GPM. It is installed by hydraulic technicians and equipment mechanics working on mobile and stationary hydraulic circuits requiring a reliable threaded connection without a locking sleeve mechanism.\u003c\/p\u003e\n\u003cp\u003eThis coupler is suited for use with hydraulic tools and skid loader attachments operating within its rated pressure range. The no-lock design allows for quick disconnection without a secondary locking collar, making it appropriate for lower-cycle applications where a locking sleeve is not required by the system design. It conforms to ISO 16028 standards, ensuring dimensional and performance compatibility with compliant hydraulic system components in both light industrial and construction equipment environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eNo-lock female pipe thread design for straightforward connection and disconnection\u003c\/li\u003e\n  \u003cli\u003eMaximum working pressure of 4568 psi for demanding hydraulic applications\u003c\/li\u003e\n  \u003cli\u003e9\/16-18 SAE threaded connection on a 1\/4-inch body diameter\u003c\/li\u003e\n  \u003cli\u003eMaximum flow rate of 3.00 GPM\u003c\/li\u003e\n  \u003cli\u003eStraight body shape, 2.08 inches overall length\u003c\/li\u003e\n  \u003cli\u003eMeets ISO 16028 standards for flat-face quick-disconnect couplings\u003c\/li\u003e\n  \u003cli\u003eSteel construction for durability in hydraulic service conditions\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eRated for use with hydraulic tools and skid loader attachments.

Depressurize and relieve residual hydraulic pressure in the circuit before disconnecting or installing any coupler. Use appropriate thread sealant compatible with hydraulic fluid and verify the mating fitting matches the 9\/16-18 SAE thread specification before final assembly. Torque to the system or fitting manufacturer specifications and inspect for leaks after system repressurization.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFitting Type\u003c\/strong\u003e: No Lock Female Pipe Thread Coupler\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Working Pressure\u003c\/strong\u003e: 4568 psi\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHose Size\u003c\/strong\u003e: 1\/4 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Diameter\u003c\/strong\u003e: 1\/4 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 9\/16-18\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Type\u003c\/strong\u003e: Threaded\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShaft Type\u003c\/strong\u003e: SAE\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShape\u003c\/strong\u003e: Straight\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Flow Rate\u003c\/strong\u003e: 3.00 GPM\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.08 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel\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: 0.25 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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-251-6FO-NL\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51544604180786,"sku":"FEM-251-6FO-NL","price":167.76,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/72d2a84d591a7bec173af63b300953e0_c8765f2e-bb13-4027-9571-2c2a4df9a32d.jpg?v=1785931197","url":"https:\/\/voomisupply.com\/products\/parker-fem-251-6fo-nl-hydraulic-coupler-1-4-in-4568-psi","provider":"Voomi Supply","version":"1.0","type":"link"}
