It connects 1\/8-inch female iron pipe (FIP) on one end to 1\/8-inch male iron pipe (MIP) on the other, using a 1\/8-27 thread form. The fitting is rated to 2800 psi and handles temperatures from -65 to 250 degrees F. At 3\/4 inch in length with a 1\/2-inch hex for wrench engagement, it installs quickly in tight spaces. The 5\/8-inch orifice restricts flow to a specified rate, making it suitable for metering applications in HVAC, plumbing, and refrigeration systems. Licensed plumbers, HVAC technicians, and gas fitters are the typical installers.\u003c\/p\u003e\u003cp\u003eThis adapter fits residential and light commercial applications where flow restriction is required at a 1\/8-inch pipe connection point. Common uses include pilot gas lines, refrigerant line accessories, instrument tubing, and low-volume fluid circuits. Its compact form factor allows installation in manifold blocks, control panels, and equipment cabinets where space is limited. The all-brass construction resists corrosion in both wet and dry service environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1\/8-inch FIP to 1\/8-inch MIP configuration for same-size restricted-flow connections\u003c\/li\u003e\n\u003cli\u003e2800 psi maximum working pressure for use in demanding fluid and gas systems\u003c\/li\u003e\n\u003cli\u003eTemperature range of -65 to 250 degrees F suits a wide variety of service environments\u003c\/li\u003e\n\u003cli\u003e5\/8-inch orifice provides consistent flow restriction without additional components\u003c\/li\u003e\n\u003cli\u003e1\/2-inch hex allows standard wrench installation in confined spaces\u003c\/li\u003e\n\u003cli\u003eBrass construction offers corrosion resistance and long service life\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or new-installation fitting for 1\/8-inch NPT pipe systems requiring flow restriction, including HVAC, plumbing, and refrigeration applications using standard 1\/8-27 threaded connections.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed plumber, HVAC technician, or qualified gas fitter in accordance with applicable local codes, IPC, or IFGC requirements. Depressurize and isolate the line before removing or installing any threaded fitting. Apply an appropriate thread sealant or PTFE tape to the male threads before assembly. Do not overtighten brass fittings, as the material is susceptible to thread damage under excessive torque.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnection Size 1\u003c\/strong\u003e: 1\/8 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnection Type 1\u003c\/strong\u003e: FIP\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnection Size 2\u003c\/strong\u003e: 1\/8 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnection Type 2\u003c\/strong\u003e: MIP\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread\u003c\/strong\u003e: 1\/8-27\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Working Pressure\u003c\/strong\u003e: 2800 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\u003eHex Size\u003c\/strong\u003e: 1\/2 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 3\/4 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOrifice Size\u003c\/strong\u003e: 5\/8 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 0.45 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 0.55 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.02 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: 12310\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MIDLAND INDUSTRIES","offers":[{"title":"Default Title","offer_id":67950450049330,"sku":"12310","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/13abcca55737fbbda975f39a08b9e7d6.jpg?v=1791718211","url":"https:\/\/voomisupply.com\/products\/midland-industries-12310-restriction-pipe-adapter-brass","provider":"Voomi Supply","version":"1.0","type":"link"}
