Constructed from steel, this fitting connects two tube ends while allowing rotational movement to reduce assembly stress. The swivel design accommodates alignment variations during installation and service. Rated to 9200 psi maximum working pressure, it is suited for demanding industrial and mobile hydraulic applications. The ORFS connection type provides a leak-resistant metal-to-metal seal backed by an O-ring, making it a reliable choice for systems where fluid integrity is critical.\u003c\/p\u003e\n\u003cp\u003eThis swivel union is used in hydraulic circuits, fluid transfer systems, and high-pressure plumbing assemblies across industrial, agricultural, and mobile equipment applications. It accommodates 3\/8 inch outside diameter tubing and uses UNF thread standards. Typical installers include hydraulic system technicians and fluid power mechanics working on equipment requiring rotationally flexible tube-to-tube connections.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eO-Ring Face Seal (ORFS) end connections for leak-resistant, high-integrity sealing\u003c\/li\u003e\n  \u003cli\u003eSwivel union design allows rotational movement to ease alignment during installation\u003c\/li\u003e\n  \u003cli\u003eSteel construction for strength and durability in high-pressure environments\u003c\/li\u003e\n  \u003cli\u003eRated to 9200 psi maximum working pressure\u003c\/li\u003e\n  \u003cli\u003eCompatible with 3\/8 inch outside diameter tubing\u003c\/li\u003e\n  \u003cli\u003eUNF thread standard for broad compatibility with standard hydraulic hardware\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation fitting for hydraulic and fluid power systems using 3\/8 inch OD tubing with O-Ring Face Seal ORFS connections and UNF threading.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by qualified hydraulic technicians or fluid power mechanics. Always depressurize and bleed the hydraulic system completely before removing or installing any fittings. Inspect the O-ring sealing surface for nicks or debris before assembly, as ORFS seals depend on a clean, undamaged face. Follow applicable industry standards for hydraulic fitting installation torque and ensure tubing is cut square and properly deburred before compression.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFitting Type\u003c\/strong\u003e: Swivel Union\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Connections\u003c\/strong\u003e: O-Ring Face Seal (ORFS)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTube Outside Diameter\u003c\/strong\u003e: 3\/8 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Working Pressure\u003c\/strong\u003e: 9200 psi\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.11 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: 6 HL6-S\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51541969633586,"sku":"6 HL6-S","price":88.67,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3119fc1125eb8629788d8a33508921ed.jpg?v=1785888628","url":"https:\/\/voomisupply.com\/products\/parker-6-hl6-s-swivel-union-o-ring-face-seal-3-8-inch","provider":"Voomi Supply","version":"1.0","type":"link"}
