Built from solid brass, this fitting handles maximum operating pressures up to 250 psi, making it suitable for compressed-air lines and light pneumatic circuits. The female coupler end accepts standard universal-series interchange couplings, while the barbed end secures directly onto compatible hose ID without additional tooling. HVAC technicians, plumbers, and general mechanical contractors install this type of fitting where a quick-disconnect coupler must transition to flexible hose in a compressed-air or fluid-transfer application.\u003c\/p\u003e\n\u003cp\u003eThe 28691 is suited for residential and light commercial pneumatic installations where a universal-series coupler interface is required. Its compact profile measures approximately 2.7 inches in length and 0.95 inches in height, allowing installation in space-constrained equipment rooms, utility closets, and mechanical chases. The brass construction resists corrosion in moist or humid environments common to HVAC and plumbing mechanical spaces. This fitting is part of the Midland Industries Universal Series Coupler line, which covers a range of body sizes and hose barb configurations for pneumatic service.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1\/4-inch female coupler body mates with standard universal-series interchange couplings\u003c\/li\u003e\n  \u003cli\u003e3\/8-inch hose barb end secures to matching hose ID without additional adapters\u003c\/li\u003e\n  \u003cli\u003eRated to 250 psi maximum operating pressure for compressed-air service\u003c\/li\u003e\n  \u003cli\u003eBrass construction provides corrosion resistance in humid mechanical environments\u003c\/li\u003e\n  \u003cli\u003eCompact form factor at 2.7 inches length supports installs in tight spaces\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation fitting for pneumatic systems using universal-series hose ID couplers with a 1\/4-inch body and 3\/8-inch hose barb connection.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by licensed HVAC technicians, plumbers, or qualified mechanical contractors. Before servicing any compressed-air line, depressurize the system fully and verify pressure is at zero before disconnecting or installing fittings. Secure the hose barb end onto compatible hose using an appropriate clamp to prevent blowoff under pressure. Follow applicable codes and the equipment manufacturer guidelines for maximum system pressure ratings.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Size 1 (Female Coupler Body)\u003c\/strong\u003e: 1\/4 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Type 1\u003c\/strong\u003e: Female Coupler\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Size 2 (Hose Barb)\u003c\/strong\u003e: 3\/8 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Type 2\u003c\/strong\u003e: Hose Barb\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Operating Pressure\u003c\/strong\u003e: 250 psi\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Brass\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 2.7 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 0.95 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 0.9 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.245 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Universal Series Couplers\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: 28691\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MIDLAND INDUSTRIES","offers":[{"title":"Default Title","offer_id":67950569619762,"sku":"28691","price":19.3,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5e781689599d2ada405db0fee9978e0d_cc2fae14-f589-4dd6-91d7-88ba18ff11a8.jpg?v=1791721656","url":"https:\/\/voomisupply.com\/products\/midland-industries-28691-universal-hose-id-coupler-brass","provider":"Voomi Supply","version":"1.0","type":"link"}
