Built from 303 stainless steel with a Buna-N\/Nitrile rubber seal, this straight-body socket features a 3\/4 inch female NPTF port on the inlet side and a 3\/4 inch female ISO-B quick disconnect interchange on the coupling side. It is rated for use in hydraulic fluid service lines where corrosion resistance and reliable sealing under pressure are required. Hydraulic technicians and fluid power mechanics are the primary installers of this fitting type.\u003c\/p\u003e\n\u003cp\u003eThis coupling socket is suited for industrial and mobile hydraulic applications where ISO-B interchange compatibility is specified. The straight orientation makes it a practical choice for inline connections on hydraulic tool lines, equipment circuits, and service hose assemblies. The NPTF thread form provides a pressure-tight mechanical seal without relying solely on thread sealant, which is standard practice in hydraulic plumbing.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eH-Series ISO-B interchange design for broad cross-compatibility with ISO-B male stems\u003c\/li\u003e\n  \u003cli\u003e303 stainless steel body for corrosion resistance in wet or chemically active environments\u003c\/li\u003e\n  \u003cli\u003eBuna-N\/Nitrile rubber seal rated for petroleum-based hydraulic fluids\u003c\/li\u003e\n  \u003cli\u003e3\/4 inch female NPTF inlet provides a pressure-tight threaded connection\u003c\/li\u003e\n  \u003cli\u003eStraight body orientation for clean inline hydraulic plumbing\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with ISO-B interchange male stem couplings in H-Series hydraulic quick disconnect systems.

Depressurize and bleed the hydraulic circuit fully before removing or installing any coupling. Apply an appropriate thread sealant or PTFE tape to the NPTF threads per the system manufacturer's recommendations and applicable fluid power standards. Inspect the Nitrile seal for damage before placing the coupling into service.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: H-Series\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShape\/Orientation\u003c\/strong\u003e: Straight\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInlet Connection\u003c\/strong\u003e: 3\/4 inch Female NPTF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoupling End\u003c\/strong\u003e: 3\/4 inch Female ISO-B Quick Disconnect Interchange\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Material\u003c\/strong\u003e: 303 Stainless Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeal Material\u003c\/strong\u003e: Buna-N\/Nitrile Rubber\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoupling Type\u003c\/strong\u003e: Socket\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: DIXON\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 6hf6-s\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"DIXON","offers":[{"title":"Default Title","offer_id":51149819445554,"sku":"6HF6-S","price":171.82,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/305986185.jpg?v=1778601700","url":"https:\/\/voomisupply.com\/products\/dixon-6hf6-s-hydraulic-qd-coupling-3-4in-nptf-iso-b-ss","provider":"Voomi Supply","version":"1.0","type":"link"}
