The larger port accepts 1\/2-inch female NPTF (1\/2-14 thread) and the smaller port accepts 1\/4-inch female NPTF (1\/4-18 thread). The fitting measures 1.28 inches in length with a 1.06-inch hex for wrench engagement. Rated to 1200 psi, it is built for demanding plumbing, pneumatic, and fluid-transfer applications. Plumbers, pipefitters, and HVAC technicians install this fitting when transitioning between pipe sizes within a threaded system.\u003c\/p\u003e\u003cp\u003eThis reducing coupling is suited for residential and light commercial piping systems where a size reduction from 1\/2-inch to 1\/4-inch line is required. Common install scenarios include instrument take-offs, gauge connections, and branch reductions in compressed air, water, oil, or gas lines. The NPTF thread form creates a pressure-tight mechanical seal without relying solely on thread sealant, making it appropriate for higher-pressure service lines.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1200 psi pressure rating for demanding service applications\u003c\/li\u003e\n\u003cli\u003e1\/2-inch Female NPTF x 1\/4-inch Female NPTF connection for in-line size reduction\u003c\/li\u003e\n\u003cli\u003e1.06-inch hex allows standard wrench engagement for secure installation\u003c\/li\u003e\n\u003cli\u003eBrass construction compatible with aluminum, brass, bronze, copper, iron, and steel pipe\u003c\/li\u003e\n\u003cli\u003eOperating temperature range of -65 to 250 degrees F\u003c\/li\u003e\n\u003cli\u003eCompact 1.28-inch length minimizes installation footprint in tight spaces\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eCompatible for use with aluminum, brass, bronze, copper, iron, and steel pipe.

Shut off and depressurize the system fully before disassembling or installing any threaded fitting. NPTF threads are designed to seal on the thread form itself, but applying an appropriate thread sealant or PTFE tape per system requirements is standard practice. Avoid over-tightening, which can crack brass fittings or distort the thread engagement.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnection Size 1\u003c\/strong\u003e: 1\/2 inch Female NPTF (1\/2-14 thread)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnection Size 2\u003c\/strong\u003e: 1\/4 inch Female NPTF (1\/4-18 thread)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePressure Rating\u003c\/strong\u003e: 1200 psi\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTemperature Range\u003c\/strong\u003e: -65 to 250 degrees F\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 1.28 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHex Size\u003c\/strong\u003e: 1.06 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 1.15 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.19 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Brass\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: 119AH-DB\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MIDLAND INDUSTRIES","offers":[{"title":"Default Title","offer_id":67948877644082,"sku":"119AH-DB","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/719220435cc687476f9ad4b4f46a0180_0228fd7f-9969-472a-8436-65aa1a81802f.jpg?v=1791675636","url":"https:\/\/voomisupply.com\/products\/midland-industries-119ah-db-heavy-reducing-coupling-brass","provider":"Voomi Supply","version":"1.0","type":"link"}
