Built from zinc-plated steel, it handles a maximum working pressure of 4000 psi, making it suitable for demanding hydraulic and fluid-power circuits. The straight body keeps the connection inline with no angular offset. This fitting is installed by hydraulic technicians, industrial maintenance mechanics, and fluid-power specialists during system assembly or repair. Its O-ring face seal on the male end provides a reliable, leak-resistant connection without relying solely on thread interference.\u003c\/p\u003e\u003cp\u003eThis adapter is used in industrial hydraulic systems, mobile equipment, and fluid-power plumbing where a transition between a straight thread O-ring port and an NPTF female fitting is required. Typical applications include pump ports, valve manifolds, cylinder lines, and other high-pressure hydraulic plumbing. The zinc-plated steel construction provides corrosion resistance for use in shop and field environments. It is suited for both original equipment installation and maintenance replacement work in commercial and industrial settings.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e4000 psi maximum working pressure for high-demand hydraulic circuits\u003c\/li\u003e\n\u003cli\u003eMale straight thread O-ring end delivers a leak-resistant seal at the port connection\u003c\/li\u003e\n\u003cli\u003eFemale NPTF thread provides a dry-seal tapered pipe thread connection on the mating end\u003c\/li\u003e\n\u003cli\u003eZinc-plated steel construction resists corrosion in industrial environments\u003c\/li\u003e\n\u003cli\u003eStraight fitting shape keeps the fluid path inline with no angular deviation\u003c\/li\u003e\n\u003cli\u003e1-3\/8 inch hex size accommodates standard open-end and combination wrenches\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or system-build component for industrial hydraulic and fluid-power plumbing that requires a male straight thread O-ring to female NPTF straight adapter at 4000 psi working pressure.\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 removing or installing any fitting. Use a calibrated torque wrench with the 1-3\/8 inch hex to avoid overtightening, which can crack ports or distort the O-ring groove. Inspect the O-ring for nicks or damage before assembly and replace it if any defects are present.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMale Thread Size\u003c\/strong\u003e: 1-1\/16-12\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFemale Thread Size\u003c\/strong\u003e: 3\/4 inch NPTF\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnection Type\u003c\/strong\u003e: Male Straight Thread O-Ring x Female NPTF\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Working Pressure\u003c\/strong\u003e: 4000 psi\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFitting Shape\u003c\/strong\u003e: Straight\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHex Size\u003c\/strong\u003e: 1-3\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1-3\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Zinc-Plated Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 40175305\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: 12-3\/4 F5OG-S\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51540209598770,"sku":"12-3\/4 F5OG-S","price":22.46,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/493c6dcbd3e65db671957850d1137080.jpg?v=1785848905","url":"https:\/\/voomisupply.com\/products\/parker-12-3-4-f5og-s-pipe-adapter-4000-psi-straight-thread-o-ring","provider":"Voomi Supply","version":"1.0","type":"link"}
