Constructed from steel with an NPSF thread interface, this coupler handles a maximum working pressure of 4568 psi and supports a maximum flow rate of 3.00 GPM. The straight body measures 1.96 inches in overall length with a 0.25 inch body diameter and accepts a 1\/4-18 thread size. It is installed by hydraulic technicians and equipment mechanics on mobile and stationary hydraulic circuits where a reliable, tool-free disconnect is not required.\u003c\/p\u003e\u003cp\u003eThis coupler is suited for use with hydraulic tools and skid loader attachments operating within its rated pressure range. The no-lock design simplifies installation in low-cycle or semi-permanent connections where the coupler will not be disconnected under pressure. It conforms to ISO 16028 standards, making it a recognized choice for standardized hydraulic circuit assemblies in agricultural, construction, and industrial equipment service applications.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eNo-lock female pipe thread design for straightforward, semi-permanent hydraulic connections\u003c\/li\u003e\n\u003cli\u003eMaximum working pressure of 4568 psi for demanding hydraulic service\u003c\/li\u003e\n\u003cli\u003eMaximum flow rate of 3.00 GPM\u003c\/li\u003e\n\u003cli\u003eSteel construction for durability in hydraulic tool and equipment environments\u003c\/li\u003e\n\u003cli\u003eNPSF threaded shaft type with 1\/4-18 thread size\u003c\/li\u003e\n\u003cli\u003eConforms to ISO 16028 standards\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 bleed the hydraulic system fully before connecting or disconnecting any fittings. Use appropriate thread sealant rated for hydraulic service on NPSF threads and tighten to the fitting manufacturer's guidelines. Inspect threads and sealing surfaces for damage before installation to prevent leaks under pressure.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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\u003eMaterial\u003c\/strong\u003e: Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/4-18\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShaft Type\u003c\/strong\u003e: NPSF\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: 0.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.96 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Working Pressure\u003c\/strong\u003e: 4568 psi\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\u003eConnection Type\u003c\/strong\u003e: Threaded\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShape\u003c\/strong\u003e: Straight\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\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-251-4FP-NL\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51541232681266,"sku":"FEM-251-4FP-NL","price":192.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/bed715df9a9be929c1ec27184d5c4dce.jpg?v=1785870426","url":"https:\/\/voomisupply.com\/products\/parker-fem-251-4fp-nl-hydraulic-coupler-1-4-in-4568-psi","provider":"Voomi Supply","version":"1.0","type":"link"}
