It features a 7\/8-14 thread size and a 0.5-inch body diameter, conforming to SAE standards for O-ring boss fittings. This coupler creates a leak-resistant connection by seating an O-ring against a machined boss face, eliminating the need for thread sealants. It is used in medium- to high-pressure hydraulic circuits on mobile equipment, industrial machinery, and power units. Licensed hydraulic technicians and fluid power specialists are the primary installers.\u003c\/p\u003e\u003cp\u003eThis fitting is suited for hydraulic systems where reliable, reusable connections are required at pressures up to 3,000 psi. The SAE ORB configuration makes it a common choice in construction equipment, agricultural machinery, and industrial power units where standardized port connections are specified. Its steel construction handles the mechanical stress and vibration typical of mobile hydraulic installations.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eBall O-Ring Boss coupler design provides a positive, leak-resistant seal without thread sealant\u003c\/li\u003e\n\u003cli\u003eRated to 3,000 psi working pressure for medium- to high-pressure hydraulic service\u003c\/li\u003e\n\u003cli\u003e7\/8-14 thread size per SAE ORB standard\u003c\/li\u003e\n\u003cli\u003e0.5-inch body diameter for consistent flow and compatibility with standard hose ends\u003c\/li\u003e\n\u003cli\u003eSteel construction for durability under mechanical stress and vibration\u003c\/li\u003e\n\u003cli\u003eSingle-piece package quantity suitable for individual replacement or repair jobs\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement fitting for SAE O-ring boss hydraulic hose and port connections rated at 3,000 psi with a 7\/8-14 thread.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified hydraulic technician or fluid power specialist. Depressurize and isolate the hydraulic circuit completely before disconnecting or installing any fittings. Inspect the O-ring for damage before assembly and ensure the boss port face is clean and free of burrs. Follow applicable SAE and equipment manufacturer torque guidelines for ORB fittings to avoid over-tightening or seal distortion.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFitting Type\u003c\/strong\u003e: Ball O-Ring Boss Coupler\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 7\/8-14\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePressure Rating\u003c\/strong\u003e: 3,000 psi\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody Diameter\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShaft Type\u003c\/strong\u003e: SAE\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.58 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 4050-16\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51540035109170,"sku":"4050-16","price":91.98,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0c0c8d8c557874571c6d9515975bdf0f.jpg?v=1785845528","url":"https:\/\/voomisupply.com\/products\/parker-4050-16-ball-o-ring-boss-coupler-3000-psi-7-8-14","provider":"Voomi Supply","version":"1.0","type":"link"}
