Rated to 3000 psi maximum working pressure, it is built for demanding industrial fluid and pneumatic systems where pressure integrity and thread sealing are critical. The hex body measures 1-3\/4 inches across flats, allowing standard wrench engagement for a secure, leak-resistant makeup. Plumbers, pipefitters, and industrial maintenance technicians install this fitting when a reducing connection is required between two NPTF-threaded components in the same straight axis.\u003c\/p\u003e\u003cp\u003eThis bushing is suited for use in hydraulic lines, compressed air systems, industrial fluid distribution headers, and plant utility piping wherever a 1-1\/4 inch MNPTF port must be stepped down to a 1\/2 inch FNPTF connection. The NPTF thread form provides a dry-seal engagement that controls leakage at the thread flanks without relying solely on sealant, making it appropriate for higher-pressure service in both stationary and mobile equipment installations.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e3000 psi maximum working pressure for demanding industrial service\u003c\/li\u003e\n\u003cli\u003e1-1\/4 inch MNPTF male thread reduces to 1\/2 inch FNPTF female thread in a straight configuration\u003c\/li\u003e\n\u003cli\u003e1-3\/4 inch hex size allows secure wrench engagement during installation and removal\u003c\/li\u003e\n\u003cli\u003eNPTF dry-seal thread form controls leakage at the thread interface\u003c\/li\u003e\n\u003cli\u003eCompact straight bushing profile — 1.47 inches in length — minimizes space requirements in tight plumbing layouts\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or new-installation fitting for industrial piping systems using 1-1\/4 inch MNPTF male ports and 1\/2 inch FNPTF female connections in straight-run reducing applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified pipefitter or industrial maintenance technician familiar with NPTF thread assembly practices. Shut off and depressurize the system completely before removing or installing any threaded fitting. Apply an appropriate thread sealant or PTFE tape in accordance with the system fluid compatibility and applicable plumbing or mechanical codes. Do not over-tighten; use a calibrated torque procedure based on the fitting size and system requirements as specified by the system designer.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMale Thread Size\u003c\/strong\u003e: 1-1\/4 inch MNPTF\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFemale Thread Size\u003c\/strong\u003e: 1\/2 inch FNPTF\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnection Type\u003c\/strong\u003e: MNPTF x FNPTF\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFitting Shape\u003c\/strong\u003e: Straight\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Working Pressure\u003c\/strong\u003e: 3000 psi\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHex Size\u003c\/strong\u003e: 1-3\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 1.47 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 1.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 1.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.51 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: 1 1\/4 X 1\/2 PTR-S\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51540129153330,"sku":"1 1\/4 X 1\/2 PTR-S","price":65.14,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f69e876fa6a409d4c56b523f0ca8919e.jpg?v=1785846488","url":"https:\/\/voomisupply.com\/products\/parker-1-1-4-x-1-2-ptr-s-pipe-bushing-3000-psi-mnptf-x-fnptf","provider":"Voomi Supply","version":"1.0","type":"link"}
