Constructed from zinc-plated steel, this fitting provides corrosion resistance in demanding fluid and pneumatic systems. It carries a maximum working pressure rating of 6000 psi, making it suitable for high-pressure hydraulic lines. The 1\/4-18 NPTF thread ensures a pressure-tight mechanical seal without relying solely on thread sealant. Licensed plumbers, hydraulic technicians, and mechanical contractors install this type of fitting in both stationary and mobile equipment applications.\u003c\/p\u003e\n\u003cp\u003eThis connector is used in hydraulic systems, fluid power circuits, and pneumatic plumbing where a reliable tube-to-port transition is required. The ORFS interface minimizes leak paths by seating an O-ring against a flat face, which is preferred in high-vibration or high-pressure environments. Typical installations include industrial machinery, mobile equipment, and HVAC or refrigeration systems that use compression-style tube fittings with NPTF ported components. This fitting is sold individually and is stocked for single-unit or small-quantity purchases.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMaximum working pressure of 6000 psi for high-pressure hydraulic service\u003c\/li\u003e\n  \u003cli\u003eO-Ring Face Seal (ORFS) to NPTF end connections reduce leak risk at the port interface\u003c\/li\u003e\n  \u003cli\u003e1\/4-18 NPTF thread standard provides a pressure-tight mechanical connection\u003c\/li\u003e\n  \u003cli\u003eZinc-plated steel construction resists corrosion in wet and oily environments\u003c\/li\u003e\n  \u003cli\u003eFits 1\/4-inch outside diameter tubing for precise compression-style assembly\u003c\/li\u003e\n  \u003cli\u003eCompact, lightweight design at 0.07 pounds for use in tight plumbing configurations\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style compression tube connector for hydraulic, fluid power, and pneumatic systems using 1\/4-inch OD tubing with NPTF-ported components and ORFS fittings.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified hydraulic technician or licensed plumber familiar with high-pressure fluid system assembly. Depressurize and drain the system fully before removing or installing any fittings. Inspect the O-ring sealing surface for nicks or contamination before assembly, and ensure the NPTF threads are clean and free of damage. Follow applicable fluid power and plumbing codes for proper fitting torque and system pressure testing procedures.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFitting Type\u003c\/strong\u003e: Compression Tube Connector\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Zinc-Plated Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Connections\u003c\/strong\u003e: ORFS x NPTF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/4-18 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: NPTF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTube Outside Diameter\u003c\/strong\u003e: 1\/4 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Working Pressure\u003c\/strong\u003e: 6000 psi\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.07 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27121700\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: 4-4 FLO-S\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51538791203122,"sku":"4-4 FLO-S","price":17.8,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a314b28f9378483a21276935b0420be2.jpg?v=1785826707","url":"https:\/\/voomisupply.com\/products\/parker-4-4-flo-s-compression-tube-connector-orfs-nptf","provider":"Voomi Supply","version":"1.0","type":"link"}
