Rated to 1,200 psi maximum working pressure and a temperature range of -65 degrees F to 250 degrees F, this fitting is built for industrial service environments. The hex drive head accepts a standard wrench for torque-controlled installation. Plumbers, pipefitters, and HVAC technicians use this type of plug to seal unused ports on manifolds, valves, and distribution headers. Brass construction provides corrosion resistance in water, oil, and low-pressure gas applications.\u003c\/p\u003e\u003cp\u003eThis hex plug is suited for residential and light commercial plumbing, HVAC refrigeration piping, hydraulic systems, and pneumatic lines where a reliable, pressure-rated pipe closure is required. Its straight fitting shape makes it a direct thread-in solution for any 1\/4 inch MNPTF female port. The compact 5\/8 inch overall length keeps the installed profile low in tight spaces.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1\/4 inch MNPTF male thread for direct installation into female NPT or NPTF ports\u003c\/li\u003e\n\u003cli\u003e1,200 psi maximum working pressure rating\u003c\/li\u003e\n\u003cli\u003eOperating temperature range: -65 degrees F to 250 degrees F\u003c\/li\u003e\n\u003cli\u003eBrass construction resists corrosion in water, oil, and compatible gas service\u003c\/li\u003e\n\u003cli\u003e9\/16 inch hex drive for standard wrench installation\u003c\/li\u003e\n\u003cli\u003eMeets ASA, ASME, and SAE standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or service fitting for any system with a 1\/4 inch MNPTF female pipe port requiring a pressure-rated hex plug closure.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by licensed plumbers, pipefitters, or qualified HVAC technicians. Shut off system pressure and depressurize the line before removing or installing pipe plugs. Apply thread sealant tape or compound rated for the service fluid before threading in. Do not overtighten brass fittings; use a calibrated torque wrench and follow applicable ASME or IPC guidelines for threaded pipe connections.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFitting Type\u003c\/strong\u003e: Hex Plug\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/4 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: MNPTF\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: 1,200 psi\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Working Temperature\u003c\/strong\u003e: 250 degrees F\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Working Temperature\u003c\/strong\u003e: -65 degrees F\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHex Size\u003c\/strong\u003e: 9\/16 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 0.625 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Brass\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ASA, ASME, SAE\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.04 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: EATON\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 3152X4\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"EATON","offers":[{"title":"Default Title","offer_id":51540147765554,"sku":"3152X4","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f825242b5a6b7e1ed62c52c295261406.jpg?v=1785847104","url":"https:\/\/voomisupply.com\/products\/eaton-3152x4-brass-hex-plug-1-4-inch-mnptf","provider":"Voomi Supply","version":"1.0","type":"link"}
