Constructed from steel, this union provides a leak-free metal-to-metal interface backed by an elastomeric face seal. It is rated for a maximum working pressure of 6000 psi and is sized for 3\/4-inch outside diameter tubing. The threaded interface follows the UNF standard. Hydraulic technicians and pipefitters install this fitting in stationary and mobile hydraulic circuits where vibration resistance and reliable sealing are required.\u003c\/p\u003e\n\u003cp\u003eThe PARKER 12 KLO-S is suited for use in industrial hydraulic systems, mobile equipment fluid circuits, and heavy-duty plumbing applications where high-pressure tube connections must be maintained without leakage. The ORFS design makes it appropriate for installations subject to vibration or pressure cycling, where flare-type or NPT fittings may be less reliable. It is used by hydraulic technicians, maintenance mechanics, and fluid power specialists working on both original equipment assemblies and field repairs.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eO-Ring Face Seal (ORFS) end connections for reliable, leak-free performance at high pressure\u003c\/li\u003e\n  \u003cli\u003eMaximum working pressure of 6000 psi for demanding hydraulic applications\u003c\/li\u003e\n  \u003cli\u003eSized for 3\/4-inch outside diameter tubing\u003c\/li\u003e\n  \u003cli\u003eUNF thread standard for compatibility with standard hydraulic fittings\u003c\/li\u003e\n  \u003cli\u003eSteel construction for strength and durability in industrial environments\u003c\/li\u003e\n  \u003cli\u003eUnion configuration allows in-line tube-to-tube joining without rotating either tube\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or service fitting for hydraulic and fluid power tube assemblies using 3\/4-inch OD tubing with ORFS end connections and UNF threading.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified hydraulic technician or pipefitter. Depressurize and lock out the hydraulic system completely before removing or installing any fittings. Inspect the O-ring sealing face and the O-ring itself for damage before assembly, and replace the O-ring if any wear or deformation is present. Refer to the applicable system schematics and torque specifications provided by the equipment manufacturer for final assembly.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFitting Type\u003c\/strong\u003e: 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\/4 inches\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: 0.92 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: 12 KLO-S\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51539174785330,"sku":"12 KLO-S","price":138.68,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f43b2d8dcf0b3135cd9b000e16a22f01.jpg?v=1785835944","url":"https:\/\/voomisupply.com\/products\/parker-12-klo-s-tube-union-o-ring-face-seal-3-4-in-6000-psi","provider":"Voomi Supply","version":"1.0","type":"link"}
