It features a 5\/16-inch push-on hose barb on one end and a 1\/4-inch male inverted flare on the other. The swivel design allows the fitting to rotate during installation, reducing hose twist and simplifying routing in tight spaces. Rated to a maximum operating pressure of 150 psi, this fitting is well suited for service lines where reliable, leak-free connections are required. Licensed HVAC and plumbing technicians are the primary installers.\u003c\/p\u003e\u003cp\u003eThis connector is used in residential and light commercial service applications where a push-on hose must transition to an inverted flare connection. Common install scenarios include refrigerant-side service lines, fuel lines, and pneumatic tubing runs where flexibility at the joint is needed. The push-on barb end accepts 5\/16-inch hose without a separate clamp in low-pressure service, while the 1\/4-inch male inverted flare end threads directly into compatible female inverted flare ports.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSwivel body reduces hose twist during installation and routing\u003c\/li\u003e\n\u003cli\u003e5\/16-inch push-on hose barb end for tool-free hose attachment\u003c\/li\u003e\n\u003cli\u003e1\/4-inch male inverted flare end for secure, leak-resistant threaded connection\u003c\/li\u003e\n\u003cli\u003eBrass construction for corrosion resistance and durability\u003c\/li\u003e\n\u003cli\u003eRated to 150 psi maximum operating pressure\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or service fitting for applications requiring a 5\/16-inch push-on hose barb to 1\/4-inch male inverted flare transition in brass.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified HVAC technician or plumber familiar with inverted flare fittings and applicable codes. Shut off and depressurize the system before removing or installing any fittings. Hand-tighten the inverted flare connection first, then use an appropriately sized flare nut wrench to seat the joint without over-torquing the brass threads. Inspect the hose barb end for proper hose seating before returning the system to service.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnection Size 1\u003c\/strong\u003e: 5\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnection Type 1\u003c\/strong\u003e: Push-On Hose Barb\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnection Size 2\u003c\/strong\u003e: 1\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnection Type 2\u003c\/strong\u003e: Male Inverted Flare\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Operating Pressure\u003c\/strong\u003e: 150 psi\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Brass\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 0.65 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 0.65 inches\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: MIDLAND INDUSTRIES\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 30278\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MIDLAND INDUSTRIES","offers":[{"title":"Default Title","offer_id":67952118530354,"sku":"30278","price":15.24,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f2be22199e7db5da712660867a04f384_7af0ad78-d2ea-4c9a-a46f-65064fd1e05c.jpg?v=1791747295","url":"https:\/\/voomisupply.com\/products\/midland-industries-30278-brass-swivel-connector","provider":"Voomi Supply","version":"1.0","type":"link"}
