Built from steel with a 1\/4-inch NPTF threaded connection, it handles working pressures up to 10,000 psi and operates across a temperature range of -35 degrees F to 250 degrees F. The straight profile and threaded shaft type make it a direct, reliable choice for in-line hose-to-valve connections. Licensed hydraulic technicians and pipefitters install this fitting in demanding environments where pressure integrity and leak-free sealing are critical.\u003c\/p\u003e\n\u003cp\u003eThis fitting is rated for use with industrial hydraulic lines and off-shore drilling applications. The 1\/4-inch hose size and 0.25-inch coupler size make it appropriate for compact hydraulic circuits operating at extreme working pressures. Part of the Parker Series 71 product line, it suits both stationary and mobile hydraulic assemblies where NPTF thread engagement provides a pressure-tight, metal-to-metal seal without requiring additional sealant tape under normal installation conditions.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMaximum working pressure of 10,000 psi for high-demand hydraulic service\u003c\/li\u003e\n  \u003cli\u003eNPTF threaded connection provides a pressure-tight metal-to-metal seal\u003c\/li\u003e\n  \u003cli\u003eSteel construction for durability in industrial and off-shore environments\u003c\/li\u003e\n  \u003cli\u003eStraight shape simplifies in-line hose-to-valve installation\u003c\/li\u003e\n  \u003cli\u003eWide temperature range: -35 degrees F to 250 degrees F\u003c\/li\u003e\n  \u003cli\u003e1\/4-inch hose and coupler size for compact hydraulic circuit integration\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with industrial hydraulic lines and off-shore drilling systems.

Depressurize and isolate the hydraulic circuit completely before removing or installing any fitting. NPTF threads are designed to seal on thread engagement alone, but always inspect threads for damage before assembly and follow the fitting manufacturer torque guidance where available. Verify system pressure rating compatibility before returning the circuit to service.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Working Pressure\u003c\/strong\u003e: 10,000 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\u003eThread Size\u003c\/strong\u003e: 1\/4 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoupler Size\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.84 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Temperature\u003c\/strong\u003e: 250 degrees F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Temperature\u003c\/strong\u003e: -35 degrees F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel\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: NPTF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShape\u003c\/strong\u003e: Straight\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 71\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFor Use With\u003c\/strong\u003e: Industrial Hydraulic Lines, Off-Shore Drilling\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: 71-3N4-4F\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51544479039794,"sku":"71-3N4-4F","price":95.56,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3e96b2e7f1e9b056bbef963a9e58cd46.jpg?v=1785927502","url":"https:\/\/voomisupply.com\/products\/parker-71-3n4-4f-hydraulic-hose-valve-fitting-1-4-in-10000-psi","provider":"Voomi Supply","version":"1.0","type":"link"}
