The 28312 features a 1\/4-inch Female NPTF connection on one end and a 1\/2-inch Male NPTF connection on the other, with an overall length of 2.94 inches. It is rated for a maximum operating pressure of 1200 psi and handles a temperature range of -65 to 250 degrees F. The steel construction provides durability in demanding industrial and mechanical applications. Plumbers, pipefitters, and HVAC technicians install this type of fitting where lines must penetrate a structural barrier while maintaining a secure, leak-resistant seal.\u003c\/p\u003e\n\u003cp\u003eThe 28312 long bulkhead connector is suited for use in hydraulic systems, pneumatic lines, fuel systems, and general-purpose plumbing where a line must pass through a panel or enclosure wall. The NPTF thread form provides a pressure-tight mechanical seal without relying solely on thread sealant. This fitting is appropriate for both residential and light commercial mechanical installations where a reducing bulkhead connection is required. Its steel construction makes it a practical choice in environments where brass fittings would be undersized for the pressure or load demands of the application.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1\/4-inch Female NPTF inlet x 1\/2-inch Male NPTF outlet for reducing bulkhead connections\u003c\/li\u003e\n  \u003cli\u003eMaximum operating pressure of 1200 psi for high-demand hydraulic and pneumatic systems\u003c\/li\u003e\n  \u003cli\u003eWide temperature rating of -65 to 250 degrees F for use across varied service environments\u003c\/li\u003e\n  \u003cli\u003eSteel construction for strength in applications where brass is not rated for the load\u003c\/li\u003e\n  \u003cli\u003eLong-body design provides additional thread engagement and panel clearance\u003c\/li\u003e\n  \u003cli\u003eNPTF threads provide a pressure-tight seal with minimal reliance on sealant compounds\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 bulkhead panel applications requiring a 1\/4-inch Female NPTF to 1\/2-inch Male NPTF reducing connection in steel construction.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed plumber, pipefitter, or qualified mechanical technician. Depressurize and isolate the system fully before removing or installing any bulkhead fitting. NPTF threads are designed to seal on the thread form itself, but applying a compatible thread sealant per the system fluid type is standard practice. Verify panel wall thickness and hole diameter to ensure proper bulkhead engagement and locknut seating before final torque.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Size 1\u003c\/strong\u003e: 1\/4 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Type 1\u003c\/strong\u003e: Female NPTF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Size 2\u003c\/strong\u003e: 1\/2 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Type 2\u003c\/strong\u003e: Male NPTF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Operating Pressure\u003c\/strong\u003e: 1200 psi\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOperating Temperature Range\u003c\/strong\u003e: -65 to 250 degrees F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.94 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 1.4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 1.55 inches\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: 0.53 pounds\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: MIDLAND INDUSTRIES\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 28312\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MIDLAND INDUSTRIES","offers":[{"title":"Default Title","offer_id":67948818399538,"sku":"28312","price":30.98,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/45722b4e082dd08acae81c5af0573394.jpg?v=1791673608","url":"https:\/\/voomisupply.com\/products\/midland-industries-28312-long-bulkhead-connector-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
