Built from solid brass, this coupler delivers durable, corrosion-resistant performance across a wide operating temperature range of -40 to 250 degrees F. The FPT configuration allows direct threaded connection to standard pipe fittings without adapters. Weighing approximately 0.475 pounds, the compact body measures 1.95 inches in length, 1.65 inches in height, and 1.55 inches in width, making it well suited for tight plumbing and pneumatic panel installations where space and flow capacity both matter.\u003c\/p\u003e\n\u003cp\u003eThis coupler is intended for use in pneumatic distribution systems found in commercial and industrial environments. It is commonly installed on air lines, compressor outlets, and pneumatic tool supply circuits where a high flow rate is critical to system performance. The ST Series high flow design reduces pressure drop across the connection point, which is important in multi-tool or high-demand compressed air setups. Licensed mechanical contractors, pipefitters, and qualified pneumatic technicians are the typical installers for this type of fitting.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eHigh flow internal design reduces pressure drop in pneumatic supply lines\u003c\/li\u003e\n  \u003cli\u003eSolid brass construction provides corrosion resistance and long service life\u003c\/li\u003e\n  \u003cli\u003e3\/4 inch FPT connection threads directly onto standard pipe fittings\u003c\/li\u003e\n  \u003cli\u003eWide operating temperature range: -40 to 250 degrees F\u003c\/li\u003e\n  \u003cli\u003eCompact body  -  1.95 inches long, 1.65 inches high, 1.55 inches wide\u003c\/li\u003e\n  \u003cli\u003ePart of the ST Series High Flow Brass Female Coupler line\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-install fitting for pneumatic systems using 3\/4 inch FPT connections in the ST Series high flow coupler family.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eDepressurize the air supply line completely before removing or installing any pneumatic coupler. Apply thread sealant tape or pipe compound rated for compressed air service to the male threads before making the FPT connection. Hand-tighten first, then wrench-tighten to a snug, leak-free fit  -  avoid over-tightening brass fittings, which can crack the threads. Verify there are no leaks under operating pressure before returning the system to full service.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Size\u003c\/strong\u003e: 3\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Type\u003c\/strong\u003e: FPT (Female Pipe Thread)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOperating Temperature Range\u003c\/strong\u003e: -40 to 250 degrees F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 1.95 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 1.65 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 1.55 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.475 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Brass\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: ST Series\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: 28673\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MIDLAND INDUSTRIES","offers":[{"title":"Default Title","offer_id":67952138420530,"sku":"28673","price":48.16,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/92d7be74b5492a80951a15e2f2becf8d_f42d93d3-2fb4-497d-bcbf-8b307ec91500.jpg?v=1791747948","url":"https:\/\/voomisupply.com\/products\/midland-industries-28673-high-flow-coupler-3-4-in-fpt-brass","provider":"Voomi Supply","version":"1.0","type":"link"}
